Description

Modified husky body with plant seed

Technical field

The present invention relates to the husky utilization of resources and desert, desert treatment field, particularly to one, there is earth Characteristic and can the modified husky body of direct growth plant.

Background technology

(1) desert, desertification and harm thereof

Desert and desertification are the great environmental problem that face of mankind nowadays is the severeest.

Whole world land surface is 1.62 hundred million square kilometres, takes up an area the 30.3% of the ball gross area, Qi Zhongyue 1/3 (48,000,000 square kilometres) are Desert Area arid, semiarid, and annual with 4～60,000 square kilometres Speed expandings.And desert area has accounted for the 10% of the land gross area, also the soil of 43% is faced with sand The threat of desertization.

China is that desert, the world is distributed one of most country, is also seriously to be endangered by dust storm and desertification in the world One of country of evil.The numeral that China national forestry bureau announced in 2011, whole nation sandy land area 173 Ten thousand square kilometres, accounting for the 18% of territory total area, wherein desert area has 80.89 ten thousand square kilometres, accounts for The 8.4% of area.

Harm in Desertification Process include stream and sand dune reach cause to farmland cover, river, reservoir, Water channel blocks, and highway buries, and also makes whole environmental degradation, loss of land resource, and related draws The regional economy risen is slow, society is unstable etc. society, economic problems.

Desertification directly results in the precious land resource that can directly utilize and drastically reduces.Desertification is directly led Causing land deterioration, Soil structure destroys, the nutrient loss of soil, and these recover to need many decades, hundreds of Year, the most thousands of years.The deterioration of grasslands that desertification causes, make the advantage grass seeds being suitable to livestock edible by The fewest, even completely lose, herbage becomes short, sparse, and yield substantially reduces, grassland capacity for raising livestock on the grasslands Greatly decline.Desertification causes river, reservoir, water channel to block, such as, and the average annual sediment transport in the Yellow River 1,600,000,000 tons, The most just there are 1,200,000,000 tons from Desertification.Desertification causes railway bed, bridge, culvert in some areas Hole is damaged, and makes highway subgrade, road surface sand, forces highway communication to be interrupted, and even makes highway discard.Due to Dust storm is pressed hard, and thousands of herdsman is forced to move to alien land, becomes " eco-refugee ".China national forestry bureau The data provided show, 20 end of the centurys, and desertify the annual speed expanded with 3436 square kilometres, every 5 years An area being equivalent to Beijing's administrative division size is just had to lose value because of desertification, the whole nation The population affected by desertification reaches 1.7 hundred million.Desertification of land, desertification not only deteriorate ecological environment, decline soil The ground productivity, threatens rivers safety, and it is poor to aggravate husky district.

Desertification causes ecosystem and natural environment deterioration, and natural disaster takes place frequently, be facing mankind the most One of serious disaster.Natural, ecological is the integral framework that a various factors mutually restricts, will be according to necessarily The poised state that keeps relative stability of rule.Desertification greatly changes the physical features on earth's surface, land, Destroy Radiation budget balance, induction weather and environmental change, cause the soil erosion of Desertification More serious, green vegetation drastically reduces, and ecological environment drastically deteriorates, and rare animals and plants disappear or extinction, Diversity of organism suffers serious destruction.After unusual weather conditions and ecosystem are destroyed, cause desertification Speed aggravation, both form vicious cycle, are degrading natural environment further, make the people of Desertification Lose the basis depended on for existence, and cause the natural disaster in other area.According to monitoring, China city Air pollutants are mainly finely ground particles, and this is closely related with desertification.Dust pollution wide geographic area people The productive life environment of the people, sandstorm is frequent, have impact on people's health.

It is huge that the seriousness of Deserts in China also resides in the population statistics involved, and it directly or indirectly affects closely The life (account for the whole world and perplexed the 40% of population by desert and desertification) of 400000000 people.China's desertification harm Direct economic loss about 64,200,000,000 yuan is annual, and the indirect economic loss that desertification and derivative harm thereof cause is about 288900000000 yuan annual.If countermeasure without effectively preventing, be in the Urumchi of desert band, Lanzhou, Xi'an, The big cities such as Yinchuan, Taiyuan, Huhehaote, Beijing, Tianjin, can become city, desert one by one eventually, Large quantities of common people will become eco-refugee.

(2) desert and the measure of desert treatment and achievement

The fundamental way of Desertification Control is the character according to hazards of sand storms, takes various technical measures, weakens The wind speed of near surface formation, reduces the sedimentary loading in air-flow, delays or stop sand dune to move forward, with reach weakening or Avoid the purpose of hazards of sand storms.For a long time, the measure of harm (sand control) that prevent and control sandy storm, Chinese scholars It is summarized as engineering sand control (mechanical) measure, controlling sediment by plant measure and chemistry sand control measure three major types.Plant Thing sand control measure and engineering sand control measure belong to reduction wind speed, weaken stream intensity, and chemical sand-fixing is then Consolidation Shamian Island, controls Shamian Island wind erosion process development.

Vegetative sand control is also called sand consolidation with biologic, is by the means such as fencing and serike, reaches to prevent and treat desert, Stablize oasis, improve husky district's environmental quality and a kind of technical measures of productive potentialities.Vegetative sand control why can Enough tackling quicksands, one is owing to psammophytes has the root system of prosperity, can consolidate the grains of sand about, in addition The accumulation of dry branches and fallen leaves, is conducive to organic gathering, promotes the pedogenesis of sand, change sand ground after rotting Character, makes drift sand tend to stable；Two be due to serike on sand dune after, add the roughness on earth's surface, Thus also increase the resistance to wind, reduce wind speed, weaken and inhibit stream activity.

The main method of vegetative sand control includes: (1) envelope sand-base cultivation grass, protects natural vegetation；(2) afforestation Fix the sand；(3) desert edge wind prevention and sand resistance forest belt is built；(4) build inside oasis and protect field, forest network.

Vegetative sand control can improve the ecological condition in vegetative coverage sand territory, promotes that sandy plant community is to good direction Development, forms stable ecosystem, is conducive to increasing bio-diversity.

But, desert area drought, cold and hot drastic change, wind great Sha is many, and natural environment is the harshest, always Being not suitable for the growth of plant on body, therefore, the effect of vegetative sand control is limited by desert characteristic and natural environment System, particularly under conditions of without irrigating, such as the time arid especially, due to water deficient, can make cultivation The plant undergrowth planted or mortality.

Sand-prevention engineering measure is to utilize weeds, crotch, and cob wall or other structures etc. set air partition on drift sand Or covering Shamian Island, prevent Sand Movement.Engineering sand control measure has fast feature of producing effects, but the protection phase is short, The most often it is applicable to the traffic line of drift sand serious harm, important industrial and mineral base, farmland and the area in residential area, And use during for protection sand-fixation plant growth.Main method has: the husky fence (high vertical sand barrier) of resistance, machinery Sand-protecting barrier (setting straw checkerboard barrier sand-protecting barrier), clay fix the sand, transporting sand engineering (lower wind-guiding, feather row and sediment transport section etc. Type).

The mechanical function principle of engineering control measure, is all the resistance of motion by increasing stream, and retardance disappears Can, make it slow down and promote the deposition of sandy soil granule, being a kind of provisional measures for sand prevention, for drift sand Harm, functions only as fixing the sand the effect of " controlling table ".

Chemical sand-fixing be moving dunes () upper spray chemical bonding material, formed on drift sand surface and cover Layer, or penetrate in the sand of top layer, loose sand material bonding is got up to form bonding course (duricrust), thus prevents wind Sand material is blown and is raised and carry by power, reaches tackling quicksand, prevents and treats the purpose of sand damage.Chemical sand-fixing is the most multiplex The area of heavy economic losses is caused, (such as airport, traffic line (railway, highway), military affairs in hazards of sand storms Facility and important industrial and mining area), and often match with vegetative sand control, complementary and transitional as vegetative sand control Measure.

The effect of chemical sand-fixing effect, not only with the character of drift sand surface particles (such as chemical composition, mechanical group Become) relevant, and also (as big in molecular structure, molecule with the physicochemical properties of chemical sand fixing material itself Little, viscosity, absorption affinity) etc. relevant.Chemical sand fixing material conventional as asphalt emulsion, oil Ye Yan ore deposit liquid, Synthetic resin, synthetic rubber etc., it is possible to use some natural organic matters, such as brown coal, peat, municipal refuse Refuse, resin etc..

Asphalt emulsion is that our times various countries apply widest material in chemical sand-fixing engineering.But, breast Change Colophonium the most also there is also because of the asphalitine in Colophonium and resin be prone to by the oxygen in air, light, heat, Moisture and microorganism etc. destroy, and oil content declines.The gradually aggravation of this change, causes asphalt performance to degenerate, As softening point raises, needle penetration declines, and ductility reduces, and causes unity layer slowly to become fragile, harden, and loses Plasticity, occurs aging, so that finally ftractureing and being destroyed by wind sapping, loses sand fixation.

(3) desert and the basic difficult and problem of existence of desert treatment

The ideal goal of control of desert is, desert can either be made stable, again can growing plant, namely make " change oasis, desert ".But, the husky body in desert is discrete particle, and the basic difficulty of control of desert is, Husky body in desert easily moves, is difficult to water conservation and stores nutrient.The most current sand control measure, people are not Difficult discovery, existing desert control method the most fundamentally solves desert and easily moves, is difficult to water conservation water-retention And store this two hang-up of nutrient.

Existing desert control method is to fix the sand to be main, no matter uses engineering (mechanical) measure, plant to arrange Executing and chemical, it is not from the attribute improving Desert Sand body itself, only avoid sand movement and then The harm caused, therefore from its method and mode, still falls within passive sand control, can to a certain extent or Person overcomes the flowability problem in desert in the short term, is but difficult to fundamentally solve desert and is difficult to water conservation water-retention Be difficult to store nutrient a difficult problem, " change oasis, desert " that distance it is desirable to still has bigger distance.

1. engineering (mechanical) measure can temporarily change the physical aspect (naturally occurring mode) that desert exists, It is a kind of provisional measures for sand prevention, for the harm of drift sand, functions only as fixing the sand the effect of " controlling table ", Desert is of short duration is tamed, it is impossible to reach the effect of " effecting a permanent cure ", long-time after, it still can be recovered in desert Carry out appearance.

2. chemical sand-fixing is the surface using sand-consolidating agent to be sprayed on sand, to reach the purpose fixed the sand, sand-consolidating agent pair Surface grains of sand constraint, forms a kind of containment vessel of stablizing, and then makes husky body stable, do not flow on grains of sand surface. But, chemical sand-fixing materials often uses spray method to be formed, and is only capable of being formed in the scope that husky surface is the thinnest Constraint, the constraint that surface is formed once is destroyed, it may be difficult to recover, and chemistry solid matter weatherability is certainly Determine its sand control and can only temporarily block the flowing of husky body, it is impossible to reaching the purpose of long-term stability, its cost has put into High.

The earliest, spraying the sand-consolidating agent used is often emulsified asphalt, and after sprinkling, sand dune surface skining is the thickest Spending little (usual 2～3cm), after using the several years (usual 3～5 years), bonding course starts to crush；Meanwhile, The emulsified bituminous materials sprayed, to environmentally undesirable, and itself is not the nutritional labeling of plant growing, therefore its Effect is only fixed the sand；Additionally asphalt material aging is poor, will not have sand fixation after break inactivation.

At present, it has been developed that many macromolecular sand-fixation agents, after sprinkling, sand dune surface skining thickness is thin (logical It is often 0.2～0.5cm), surface retains few, and dried surface is the most cracking；Meanwhile, after sand-consolidating agent sprays, It is generally required to certain time consolidation, being difficult to meet water-dispersible again or dissolve after consolidation, its water retention is the most logical Cross close top layer part hole, part blocks underground evaporation of water and realize, its material itself there is no water conservation Effect；Further, cortex itself does not have water-retaining property, it is impossible to protect containing nutrient, it is impossible to adapt to generally giving birth to of plant Long.So, the feature of sand-consolidating agent and fix the sand its long-term behaviour fixed the sand of structures shape of layer and be difficult to obtain root This guarantee.

3. the applicable elements of vegetative sand control is frequently subjected to the restriction of weather and environment

Vegetative sand control utilizes plant top resistance sand, sand, utilizes the root of plant to fix the sand, it is possible in certain journey Micro climate and micro-soil environment is changed on degree, but, the basic difficulty of vegetative sand control is that desert itself is unfavorable In plant growing, as desert is unstable and wind-driven sediment is frequent, desert is barren, water deficient and be difficult to water conservation, Plant is all had a negative impact by homoiothermics etc..

Wind-driven sediment can make plant by deflation, sand buries and sand cuts harm, and wind-driven sediment can use engineering protection Measure and chemical sand-fixing solve, but, desert water deficient and be difficult to the basic difficult problem of water conservation water-retention, make biography The suitability of system vegetative sand control receives greatly restriction.

In sum, it is desirable to obtain a kind of control of desert measure, though husky body have the same stability of soil, Water-retaining property, breathability also have the function storing nutrient, it is, make husky body " soil ", from root Solve husky body in basis easily to move, be difficult to water conservation water-retention and a difficult problem for storage nutrient so that it is plant preferably is raw Long, it is directly used in the large area sand bodies such as Desert Control after adding plant seed, and then fundamentally improves husky body Form and carry out control of desert.

Summary of the invention

In view of this, it is an object of the invention to provide a kind of modified husky body with plant seed, though husky Body has the same stability of soil, water-retaining property, breathability and has the function of storage nutrient, it is, Make husky body " soil ", fundamentally solve husky body and easily move, be difficult to water conservation water-retention and store nutrient A difficult problem so that it is plant growing preferably, is directly used in the large area sand bodies such as Desert Control after adding plant seed, And then fundamentally improve the form of husky body and carry out control of desert.

The husky internal blending of described modification has plant seed.

The invention also discloses a kind of modified husky body with plant seed, by husky, water with consolidating of water can be dissolved in State organic substance can bond the grains of sand and be formed, and after mix, the described solid organic materials that can be dissolved in water dissolves Yu Shuizhong and being formed has the solution of caking property and adhesiveness the adhesion grains of sand and seed, the modified husky body of formation It it is pellet pores structure；Moisture in the described solution with caking property and adhesiveness can stick to solution Between the grains of sand；After moisture evaporation in the described solution with caking property and adhesiveness, therein can be dissolved in water Solid organic materials can bond the grains of sand and meet after water and can again be dissolved in the water and be formed and there is caking property With the solution of adhesiveness and the adhesion grains of sand；

The husky internal blending of described modification has plant seed.

Further, after there is between the grains of sand of modified husky body the water evaporation in caking property and adhesiveness solution, its In solids mass-energy the grains of sand are bonded together；The described water evaporation having in caking property and adhesiveness solution After, the weight ratio between the solid organic materials that can be dissolved in water therein and husky body is 1:30-8000；

Further, between the grains of sand of modified husky body, there is interconnected pore and dead-end pore；

Further, the described solid organic materials that can be dissolved in water includes natural polymer and modified material thereof and conjunction Become one or both and the above mixture in polymer substance；

Further, it is also added with being scattered in the natural polymer in described solution and modified material thereof and synthesis One or both and above mixture in polymer substance.

Further, organic polymer auxiliary agent, little molecule auxiliary agent, surfactant inorganic active powder it are also added with Or the one in powder material, inorganic inactive powder or powder material, solid substance and pH value Auto-regulator Or two kinds and above mixture；

Further, the described solid organic materials that can be dissolved in water is polyvinyl alcohol, polyethylene glycol oxide, poly-second two One in alcohol, sodium polyacrylate, sodium carboxymethyl cellulose, hydroxypropyl methyl cellulose and cellulose ether or Two kinds and above mixing or copolymer；

Beneficial effects of the present invention: the modified husky body of the present invention has the soil being similar to plant plant seed, Such as from stability, both there is between soil particle time wet certain adhesion, can occur again The change of grain arrangement, so, soil time wet presents viscoelastroplasticity character to a certain extent；And time dry Node between soil particle is restrained, and the restrained power of arrangement between granule is fixed, so soil when doing Presenting certain solid property, therefore, the soil when soil time the wettest is still done, the present invention changes Property sand body i.e. has this mechanical stability；From water-retaining property, storage nourish one's nature can, can deposit between soil particle Water storage divides, nutrient and air, and after moisture evaporation can also re-absorption moisture, and the application's is modified husky Body i.e. has water conservation water-retention and the characteristic of storage nutrient；Further, owing to using the form of solution, this formation is molten The system that the solid matter of liquid is formed with husky, water is relatively stable, and the feature of its caking property and adhesiveness is difficult to flow Lose.

The modified husky body of the present invention makes general husky body " soil ", fundamentally change husky body granule it Between interaction relationship, constitute and there is the pellet pores structure of adhesion (cohesive strength), make husky body possess Stable and storage moisture, the performance of nutrient as soil；By modifies for sand and obtain absorbing moisture, Store moisture, nutrient and air and there is the modified husky body of certain mechanical stability, it is possible to for the growth of plant Solid condition is provided, meanwhile, with the addition of seed, directly apply, save program and cost, be preferable The measure of Desert Control；Meanwhile, modified husky body also can as the means of the husky resource utilizing sandy beach, sand ground, Carry out plant growing.

Comparing with other control of desert measure of prior art, the present patent application has the advantage that

1. compared with fixing the sand with engineering

Engineering Sand-fixing Measures changes the roughness on drift sand formation surface, do not improve husky body self structure composition and The way of restraint, only serves the effect that physics improves.The present invention by bonding solid matter improve husky body Grain composition rule, while improving the way of restraint of husky body granule so that it is structure have water conservation, water-retention, Keeping the function of nutrient, it is, make husky body " soil ", this modified husky body is more suitable for plant growing.

2. compared with chemical sand-fixing method

The present invention is embodied in many aspects from the different of chemical sand-fixing.

First, present invention achieves " soil " of husky body, the method that realizes with chemical sand-fixing and make apparatus There is fundamental difference.

The present invention uses having water conservation, bond and store the constraint solid matter of the effects such as nutrient function with The method of husky body mix, its effect can realize " soil " of husky body, and can plant various plant, and Chemical sand-fixing is only by the method for surface spraying chemical sand-fixing materials, and its effect is only capable of realizing the consolidation of surface sand body, Prevent the movement of husky body.Constraint solid matter and husky body mix under certain condition that the present invention uses are formed and change Property sand body, the modified husky body of formation has water-retaining property, function is supported in storage, and the constraint solid-state that uses of the present invention The modified husky body that material is formed all has good stability in dry, wet two states, and the constraint of formation can root Reconfigure according to the change of dry and wet state, change.The present invention is the overall constraint system changing husky body, and The constraint system only strengthening husky surface is essentially different.The present invention is used for desert, can be by sand The husky system of surface 3～50cm is made modified husky body, and then makes the husky body in desert be difficult to flowing, is provided simultaneously with The moisture of plant growing indispensability and nutrient, reach the purpose of basic sand control.Chemical sand-fixing measure is by husky body Surface sprinkling chemical sand-fixing materials, by the infiltration (length of penetration is generally less than 3cm) of sand-consolidating agent to surface sand body Constraint strengthen, only change the way of restraint of husky surface, its degree of depth is the most shallower, and its constraint has Irrecoverability, the impact on natural environment is relatively big, and ordinary disbursements is high.The effect of cured layer itself is single, Consolidation can only be provided, not there is the function of water conservation, water storage, and nutrient.

The present invention and the intensity mechanism fundamental difference of chemical sand-fixing.

Chemical sand-fixing is the consolidation by realizing surface sand body at husky surface sprinkling chemical consolidation material, for Playing the effect of the overall husky body of consolidation, surface sand body requirement of strength is higher, comprcssive strength even to exceed 1MPa could really prevent destruction and the movement of husky body, and the present invention is then in the range of certain thickness, by sand Body with there is bonding, the constraint solid matter of water retaining function mixes, it is achieved the pact each other of overall husky body Bundle, will prevent the movement of husky body, and the constraint of husky body reality is not required to the strongest, and this point can be come with soil Analogy, from the point of view of test, after using the present invention, husky body is in a way, it is achieved that " soil ", though So by regulation constraint solid matter type and consumption, the surface consolidation strength of husky body can be accomplished foot completely Enough height, but test and analysis show, and the surface comprcssive strength of husky body can play stable in the least scope The effect of husky body, can reach chemical sand-fixing effect, " the soil of husky body in the range of achieving again certain thickness Change ", get final product planting plants simultaneously, it is achieved fix the sand again and eucyclic purpose.

Compared with chemical sand-fixing, the present invention also has the restorability after constraint destroys.

The performance of the constraint solid matter that the present invention uses determines the spy of the restorability of modified husky destruction Point, the constraint solid matter that the present invention uses is dissolvable in water in water, the liquid object after dissolving and husky body mix shape After becoming modified husky body, moisture therein is difficult to lose, even if after loss of water, if meeting water again, retrains solid-state Material can be dissolved in the water again, re-forms the modified husky of same purpose, and this process can the most repeatedly, Therefore the modified husky body that the present invention is formed has the restorability of destruction, but chemical sand-fixing is the most entirely different, changes Learning the material behavior fixing the sand to use and determine the irrecoverability of destruction, chemical sand-fixing is in order to ensure surface sand body Consolidation, higher frequently with intensity and not there is the sand fixation material of reversal properties, but surface strength is once broken Bad, it is impossible to recover, sprayed on material could recur and arrive consolidation, otherwise the most again the most again After surface sand body destroys, husky body below is exposed to surface again, accumulates over time, original fixes the sand Effect will progressively be lost, and fix the sand purpose and effect just cannot ensure.

As can be seen here, the present invention makes the method for modified husky body and by the infiltration of chemical sand-fixing materials by mix The method fixed the sand is inherently different.

3. compared with vegetative sand control method

The present invention with the fundamental difference of vegetative sand control is, vegetative sand control can only " be taken stopgap measures ", and the present invention be from Fundamentally change husky volume property, it is achieved husky body " soil ", thus realize vegetative sand control truly, Therefore the present invention is only the arranging of " effecting a permanent cure " of control of desert.

Vegetative sand control utilizes rhizome that the mode that husky body retrains plays the effect fixed the sand, but husky body self property Matter is not appropriate for plant growing, and moisture easily runs off, and husky body also cannot be stablized, and under wind effect, husky body moves Frequently, plant is difficult to grow, though short-term plant growing, in the presence of a harsh environment, if moisture can not effectively be protected Depositing, plant is also difficult to continued growth, the most withered, and therefore the effect of vegetative sand control is not only by local climate The restriction of condition, is also difficult to realize its effect fixed the sand for a long time.The present invention then has not with vegetative sand control With.The present invention is the basic point from vegetative sand control, and the performance improvement of i.e. husky body is started with, it is achieved husky body " soil ", not only has the effect of stabilized sand body, also makes husky body have water conservation, water-retention, storage nutrient Function, make husky body possess the condition of plant growing, it is achieved that the stable and condition of plant growing of husky body, Plant growing also could really realize, and therefore for certain angle, the present invention is only the plant of real meaning Fix the sand.

In order to contrast the effect of the present invention and vegetative sand control, the present invention has also carried out contrast test.By this Bright method takes sodium polyacrylate as having the solid matter of bonding, water retention in modified sand, thus Formed modified husky, by modified husky and moistening common husky body making simultaneously in outdoor crushed stone, placement thickness Being 15cm, and dispense multiple Semen Allii Tuberosi and grass seed on surface respectively, after 1 day, common husky body becomes dry, this Wetting state is remained in that behind the husky some skies of modification of bright interpolation plant seed, and on the premise of not watering, Grass seed and the Semen Allii Tuberosi on modified husky surface germinate, but the grass seed of common husky surface and Semen Allii Tuberosi are withered dry again after germinateing Extremely, after the plant that modified sand is above planted, once water and can meet the water yield of plant in interval for 10-30 days Demand, the seedling on modified sand grew up through 2 years, had reached about two meters, the Fructus Lycopersici esculenti of modified husky upper plantation Can normally eat with dish Seedling, suitable with planting plants growing way in soil.After planting 1 year, root system of plant will Sha Tilian is netted, and the outward appearance of soil, character are all without difference, and the plant that former years rot can be described as again nutrient, Husky body is stable further, and modified husky plantation effect forms benign cycle, and sand fixation is the most feasible, warp Ji, also makes desert become fertile soil and is possibly realized.

4. compared with other method: such as water-absorbing resins；

Super absorbent resin is containing strongly hydrophilic group, is generally of the macromolecular material of certain degree of cross linking. Super absorbent resin is water insoluble and organic solvent, and water absorbing capacity is generally the hundreds to thousands times of own wt. After the water suction of this material swelling for hydrogel, after pressurized, water is not easy to extrusion；Resin is dried, can be the most Secondary water suction, its moisture overwhelming majority absorbed can slowly discharge, and utilizes for plant absorption.

The constraint solid matter that super absorbent resin and the present invention use has essential distinction.The constraint of the present invention Solid matter has caking property and adhesiveness, has water solublity, relies on the caking property of constraint solid matter and glues Attached property forms constraint with husky body.This constraint can present different character along with dry, wet change, constraint Also can reconfigure.

5. the present invention has significant economy, exploitativeness and the feature of environmental protection.

First, the modified husky body that the present invention is formed is compared with existing sand fixing technology, and its disposable investment construction becomes Originally there is certain economic benefit.The constraint material that the present invention uses can be formed under conditions of volume is minimum Meet the modified husky body required, as take some solid organic materials that can be dissolved in water include natural polymer and One or both and above mixture in its modified solid matter and synthesis macromolecule solid matter；As: Polyvinyl alcohol, polyethylene glycol oxide, Polyethylene Glycol, sodium polyacrylate, sodium carboxymethyl cellulose, hydroxypropyl first One or both and above mixing in base cellulose and cellulose ether or copolymer, constraint material only accounts for sand A few one thousandth of body weight ratio, and material is for commonly using chemical materials, material cost is relatively low, therefore from former Say in reason that material cost is relatively low, and construction method is the most relatively simple, only with the common process such as stirring, machine Tool, labour cost are relatively low, and therefore comprehensive method of investment cost will have considerable economy.With carboxymethyl cellulose As a example by element sodium, adding 20kg sodium carboxymethyl cellulose material in 1 cubic meter of water, market unit price is 10 yuan/kg； Correctability sand body about 4 cubic metres, it is considered to artificial, machine cost 100 yuan, then modified husky body 1 cubic metre, Cost is 75 yuan, is layed in husky surface by 10cm, and 1 cubic metre of modified husky body can lay 10 square metres, then The disposable input cost of modified husky body Desert Control is 7.5 yuan/square metre.

Secondly, different from conventional sand-fixation method, the modified husky body that the present invention is formed has recyclability, once After investment construction, modified husky body can plant various plant, and modified husky physical ability stablizes root system of plant, and plant Root system stabilized sand body the most in turn, and the rhizome, the leaf etc. that rot again can be as nutrients, for husky structural reform appearance Becoming benign cycle, desert will actually change available class land resource, have once investment long-term gain Feature, therefore its indirectly economy by inestimable.

Exploitativeness of the present invention is stronger.The present invention uses material to be existing chemical industry common used material, such as poly-second Enol, polyethylene glycol oxide, Polyethylene Glycol, sodium polyacrylate, sodium carboxymethyl cellulose, hydroxypropyl methyl are fine Dimension element and cellulose ether etc. are the thickening material that chemical industry is conventional, and production method is simple, feasible, and cost is relatively Low, the construction method that additionally present invention uses is simple, and master operation is point preparation being spread on husky liquid solution and changes Property sand body mix, therefore the present invention be prone to grasp, implementation is stronger.

The present invention also has the feature of environmental protection, the constraint material of the present invention, can use the material rich in nutrition, its Itself can be the growth necessary nutrient of offer of plant, it is possible to add the necessary nutrient of plant growing wherein. The dry and wet that husky body is retrained according to husky body by the present invention can reconfigure, change, and has restorability.This The constraint material of invention uses conventional material, and such as sodium carboxymethyl cellulose, itself is also food additive, Environmentally safe, expense is low, it is easy to implement.

In summary it can be seen, the technical measures of present patent application achieve husky body soil from principle, can be from Fundamentally play the effect of sand control.

Detailed description of the invention

The husky internal blending of described modification has plant seed.

Certainly, also can add water-absorbing resins, also can add such as modified starch, modified cellulose, poly-third Olefin(e) acid salt and copolymer analog, polyacrylamide and copolymer analog thereof, polyvinyl alcohol, polyethenoxy ether class, Soybean protein class, fibroin class, pectin, alginic acid, chitosan and modifier thereof, being total to of super absorbent resin Mixed, super absorbent resin and the complex etc. of inorganic matter gel, improve water suction and the storage capacity of modified husky body； Or add fertilizer, inorganic fertilizer and composite organic-inorganic fertilizer, such as compoiste fertilizer, nitrogenous fertilizer, phosphate fertilizer and potassium Fertilizer or two-nutrient compound fertilizer nitrogen phosphorus, nitrogen potassium and the binary compound fertilizer of phosphorus potassium and N P and K NPK etc., Increase the modified husky character of body, level etc. of increasing soil fertility, all can improve the combination property of modified husky body, It is suitable for plant growing.

Experiment shows, it is possible to is repeatedly dissolved in the water and has thickening property and water solublity in water, then can The solid matter that enough formation has caking property and adhesiveness solution has multiple, does not repeats them here, such as: poly- Vinyl alcohol, polyethylene glycol oxide, Polyethylene Glycol, sodium polyacrylate, sodium carboxymethyl cellulose, hydroxypropyl methyl One or both and above mixing in cellulose and cellulose ether or copolymer；After being dissolved in the water, Can not only (such as mass percent be in the case of bigger volume (solid content after moisture evaporation) 5～10%, even 10～20% or more than 20%) make the solution with caking property and adhesiveness, Er Qieke With in the case of less volume, such as less than 5%, even less than 1%, make and there is caking property and adhesion The solution of property.Also can add some auxiliary agent during use, improve or improve caking property and the adhesion of solution further Property；Inorganic solid materials can also compound with organic solid-state material, and to obtain, we are desired has bonding Property and the solution of adhesiveness.

The solution (containing nutrient) described in Sha Tiyu with caking property and adhesiveness is mixed and after mix, just can Enough form that to have soil property, granule+constraint+hole modified husky body (can also be sand, water and can The solid matter being dissolved in the water is formed by different order mixing mix)；When wet, moisture and nutrient are deposited Storage in the solution and solution sticks in the hole between husky body granule, so, modified husky body not only has The character that water conservation storage is supported, and there is the viscoelastroplasticity character as wet soil；When dry, Yuan Xianrong Bond after solid matter consolidation in Xie Yushui the granule between modified husky body, so, modified husky body has picture The character of the porous solid that dry soil is the same, and, the solid matter after described consolidation can absorb moisture And be again dissolved in the water, so, modified husky body also has the ability of absorption moisture (containing nutrient).

In the modified husky body structure of granule+constraint+hole, owing to making the grains of sand produce adhesion (cohesive strength) Constraint this as added enter solid matter (being solution when moisture is big, moisture hour is gradually converted into solid), After solid matter filling pore, the hole of modified husky body can be less than the hole of unmodified front discrete husky body, But, owing to, after the solution mix that husky body and solid matter are formed, being no longer the most direct between the grains of sand Contact, has described solid matter between contact point so that the spacing between husky body increases (and solid matter institute After moisture evaporation in the solution formed, the solid content of solid matter itself is less, and it occupies the ratio of hole Not quite), therefore, along with the change of " loose " " tightly " of contact between granule, the hole of modified husky body also may be used With the hole more than the discrete husky body being even far longer than before modified, to sum up, the hole of modified husky body is the most permissible Be less than, can also be more than the hole of discrete husky body before modified, experiment shows, the porosity of modified husky body can To change between 10～80%, this porosity ranges is not only greater than discrete husky body, and more than nearly all The soil of type, this indicates that, we can regulate the hole of modified husky body by different proportionings and structure Rate, make husky body contain it is desirable that moisture, nutrient and air.Moreover, the granule hole of modified husky body In gap structure, both having had interconnected pore, it may have dead-end pore, wherein interconnected pore rate is 5-70%, changes Property sand body can be by interconnected pore and the outside exchange that water and air occurs.

Due in the structure of granule+constraint+hole in modified husky body, the constraint of constraint material (solid matter) The porosity of power and modified husky body can regulate, so, after the moisture evaporation in modified husky body, formation The intensity of the porous solid as dry earth can regulate in a scope the biggest, and intensity is at 10Kpa Time following, modified husky body is the more loose solid of ratio, and when intensity is between 10～50Kpa, modified husky body is into The solid that type preferably loosens, after intensity is more than 50Kpa, modified husky body gradually toughens, for terrible To modified husky body harder time dry, can be retrained by regulation and porosity so that it is intensity reaches 200Kpa Above.

The modified husky body become by sand, be exactly one " native " on mechanical state, have rheology (time wet) and Solid (time dry) two states, and, " native " of dry solid state can convert after absorbing moisture For " native " of wet rheology, and " native " of wet rheology can be converted into after moisture evaporates " native " of dry solid state, by the constraint between regulation granule and space, we can regulate modified husky The rheology (such as viscoelastroplasticity) of body this " native " or solid property, obtain from " sandy soil " to " loam " Between " clay " " native " of variety classes plant growing various, suitable；Therefore, by this Sand is become " native " by bright modified husky body, for available husky body, the mode of desert.

According to modified purpose, construction requirement or the difference of economy, low viscous solution (viscosity can be prepared Below 100mpa s), it is also possible to (viscosity is at 100mpa s～5000mpa s to prepare moderately viscous solution Between), can also configure full-bodied solution (viscosity be more than 5000mpa s) and sand body mix and formed and change Property sand body.

After preparation forms modified husky body, due to modified husky body and the extraneous exchange that moisture can occur, so, In modified husky body, the water content of solution can change, and then, the viscosity of the solution in modified husky body except with The material behavior of the solid matter added is relevant and outer, also relevant to the change of water content, but described in have After moisture evaporation in caking property and adhesiveness solution, the solid content of solid matter is geostationary, so We can determine described solid matter using the weight ratio of the solid matter added and husky body as controlled quentity controlled variable Volume.According to the difference of material character, add the solution with caking property and adhesiveness in modified husky body In the kind of solid matter and volume can select in a bigger scope, after moisture evaporation, added When the weight ratio of the solid matter entered and modification sand body is in the range of 1:30-8000, we all can obtain base Require and desired modified husky body in different modified purposes.

The modified husky body obtained based on particle confinement principle, its constraint can not only produce between sand grain Adhesion, and adhesion can be produced between husky body and other solid matter, thus Sha Tizhong doped with When appropriate gravel, plant roots, stem, skin, animal wastes, corpse residue etc., its main body will not be changed On there is the character of soil characteristic, so, method based on particle confinement, it is simple that we are possible not only to transformation Sand or sandy soil, and Gobi desert etc. can be transformed containing the husky and wasteland of other solid matter；Utilize this property Matter, we even can add rigidity or flexible fiber, fabric, rattan, film tape, sheet etc., improve or The modified husky stability of body of regulation, crack resistance or toughness；The each seed manure that can be dissolved in the water enough is added in decapacitation Outside material, nutrient, other fertilizer also is able to be constrained in modified husky body, provides nutrition for plant growing；I Can also add water-absorbing resins, acid-alkali accommodation solid matter etc., improve the modified husky water suction of body, water conservation Performance or the soda acid performance of modified husky body.

In above-described embodiment, list the solid organic materials that can be dissolved in water in modified husky body with wider scope With the weight ratio of husky body, after a large number of experiments show that again, the solid organic materials of water and the weight of husky body can be dissolved in Amount, than difference, forms modified husky body and also has different, when the solid organic materials (material that can be dissolved in water Determine) with the weight ratio of husky body more hour, Water-saving effect suitably reduces, when the solid organic that can be dissolved in water When matter (material determines) is the biggest with the weight ratio of husky body, Water-saving effect is the best, but, adapt with this It is that the adhesion strength between the grains of sand is also with being dissolved in the solid organic materials (material determines) of water and husky body The rising of weight ratio and increase, along with being dissolved in the solid organic materials (material determines) of water and husky body The reduction of weight ratio and reduce；When the solid organic materials that can be dissolved in water reaches 1:8000 with husky body weight ratio Time, modified husky body still has certain water retention, still has adhesion strength between the grains of sand, but Reduce, and can growing plant, but must suitably water to ensure growth conditions；And when being dissolved in the solid-state of water Organic substance and husky body weight increase to 1:30, and between the grains of sand of modified husky body, adhesion strength is relatively big, water conservation Effect is preferable, but modified husky body itself has the phenomenon that hardens, for sand-fixing effect clearly, certainly, also Can be used for plant growing, the modified husky body simply with the phenomenon that hardens is unfavorable for the growth of root system of plant；The most just It is to say, according to requirement to the solid organic materials physical property that can be dissolved in water in the present invention, water can be dissolved in The consumption of solid organic materials fixes the sand the most at most, water conservation, grains of sand adhesion strength preferable, the most then can drop Low, and above-mentioned scope is not merely 1:8000 to 1:30, also can suitably reduce or increase, formation Modified husky body is respectively provided with to be expected or foreseeable effect, but is suitable in desert and is formed being similar to soil Then need for plant growing to use OK range.

Above-described embodiment can not all of alternative material of limit, ratio is if dissolving and can being dissolved in water in water Solid organic materials also have a lot, do not repeat them here, all can realize goal of the invention, certainly, with low one-tenth Basis the material playing expectation function are main.

Certainly, the order by merging of said components can not limit protection scope of the present invention, can by husky, water and Can be dissolved in the solid organic materials of water mix in any order and mix and formed, after mix, described can be dissolved in The solid organic materials of water be dissolved in the water and formed there are the solution of caking property and adhesiveness the adhesion grains of sand and Form the modified husky body with pellet pores structure；Moisture in the described solution with caking property and adhesiveness Can stick between the grains of sand with solution；After moisture evaporation in the described solution with caking property and adhesiveness, Material therein can again be dissolved in the water and be formed and have the solution of caking property and adhesiveness and glue after meeting water The even grains of sand；Further, being experimentally confirmed, the result of gained there is no substantially change.

On the husky body of this modification during planting plants, whole modes of planting plants in prior art soil can be used, Including membrane curing, booth growth, with the outside severe natural environment of opposing；In a word, plant with in soil Plant does not has internal to distinguish, and does not repeats them here.

Contrast shows, after the described liquid with caking property and adhesiveness is formed modified husky body with sand mix, Pave structure sheaf again that formed in common husky surface, and described liquid is sprayed directly on common husky surface And the surface layer formed has the difference of essence, it is embodied in:

First, it is achieved fundamental difference in principle.

From the composition rule of particulate matter, modified husky body be built upon that the present inventor proposes " granule is about Bundle " on the basis of principle, it is the thinking of a kind of brand-new sand " soil ".

Constraint type between common sand is " contact ", and its contact point only exists contact pressure and frictional force, And there is no any node adhesion and combine moment (such as node pulling force and moment), therefore, common sand can only By contact pressure and frictional force balancing gravity and external force, its node can not bear pulling force and moment, otherwise, Husky body just will occur sudden change that granule arranges and unstability.

And after the liquid with caking property and adhesiveness is formed modified husky body with sand mix, its granule node Between restraining forces be " adhesion ", it can either produce opposing granule between separate restraining tensile force, again can Enough producing the restraint moment that opposing granule rotates, meanwhile, it can also produce node pressure and frictional force, therefore, All degree of freedom of granule can be limited by it, but this restriction is again limited, and granule node is producing While raw constraint reaction, it is also possible to extend, rotate and slide, therefore, its constraint type and common sand Fundamental difference, say, that modified husky body both can resist external force, again can the most limited and Stably move.On the other hand, in modified husky body, husky body whole interior be constrained to " adhering to constraint ", this Planting constraint is to be formed after sand mix by the liquid with caking property and adhesiveness, on microscopical structure, this Planting constraint is after one layer of adhesion layer of each sand surface uniform fold, contacts again and formed between granule, Therefore, this constraint has universal property and restorability, say, that equal at any point cantact between granule Can form " adhering to constraint ", and after separation, contact between granule again, this binding feature can be recovered. Therefore, modified husky body has the viscoelastroplasticity character of even macroscopic and isotropic, with the mechanics of wet soil Characteristic is the same.

Once after the moisture evaporation in modified husky body, " adhering to constraint " just will become " consolidation constraint ", the most just That the spatial arrangements between sand will be fixed, husky body can bearing load, there is some strength, performance For the character of porous solid, just as dry soil.Meanwhile, as it was previously stated, after meeting water, " consolidation constraint " Becoming again " adhering to constraint ", husky body is become viscoelastroplasticity body from solid.In modified husky body (when no matter doing Or time wet), there is connection, open space all the time, with the external world, moisture, nutrient and the exchange of air occur.

But, if only the described liquid with caking property and adhesiveness to be sprayed at husky surface, it is only capable of Forming one layer of adhesive film in husky surface, infiltration liquid under adhesive film is extremely limited, and this layer adheres to After film is dry, just become solid film, it is clear that this method itself be not based on " particle confinement " principle and Draw, also with the thinking fundamental difference of sand " soil ".It is sprayed on the adhesion layer (solidification of husky surface It is thin layer afterwards) and infiltration liquid in the thinnest scope under adhesion layer, only define about in husky surface Bundle, this constraint, by by force to weak, does not have the most even isotropic nature, comes in and goes out with the character of soil The biggest；Adhesion layer (thin layer after solidification) resides in sand grains surface, can be by the hole between sand Gap completely encloses, this with have connect, the modified sand body fundamental difference of open space, also with the think of of soil Road fundamental difference；In modified husky body constrain in modified husky body inner homogeneous, equivalence is had an effect, with nature The characteristic of soil is similar to, and sprays layer and only have an effect near surface, does not have the characteristic of natural soils.

Second, fundamental difference in architectural characteristic.

On structure dimension, the modified husky body formed after mix, its physical dimension can regulate as required, Paving thickness is changeable, when structural thickness is big, can plant the plant that plant is tall and big, and structural thickness is little Time, the plant that plant is short and small can be planted；And the thickness spraying layer is only formed near surface, its structure chi Very little being difficult to regulates as desired.

In intensity and wear properties, the modified husky body formed after mix, formation is plate body, has plate Mechanical characteristic, in the case of the strength of materials is relatively little, still possesses higher bearing capacity, reaches to fix the sand Purpose, and, the cracking of plate body or destruction, do not destroy its effect fixed the sand, play with the intensity of soil layer Principle is consistent with stability；Meanwhile, modified husky body viscoelastroplasticity in its thickness range, time the wettest Body, or porous solid time dry, all can either stablize the root system of plant, can adapt to again the growth of root system With development, with soil curing plant and adapt to root system of plant development mechanical characteristic consistent.But, spray shape The skin layer become, has the mechanical characteristic (the biggest with the characteristic difference of plate) of thin film, it is necessary to assure enough Intensity, can be only achieved the purpose fixed the sand, and top layer is once destroyed, and is just difficult to retrain the husky body under top layer, and it is solid Husky effect is just difficult to play；Meanwhile, there is no additional constraint, still between the husky body granule under top layer, surface For naturally husky body, it is impossible to stablize root system of plant, with the characteristic fundamental difference of soil.

On pore characteristic, the even pore distribution of modified husky body, there is connection and the opening contacted with the external world Hole, it is possible to the external world, moisture, nutrient and the exchange of air occur, and spray the skin layer of formation, envelope Close husky body to contact with extraneous.

In water conservation, water storage and evaporation characteristic, first, the modified husky water conservation of body, water storage principle are that water is straight Connect to be stored in the liquid with caking property and adhesiveness and (as it was previously stated, liquid removes solid matter be all Water), it is difficult to evaporate and run off, similar with the water conservation of soil, Water storage characteristics, its water conservation, storage capacity Very strong, and this ability can regulate in a bigger scope, it is possible to adapt to various plant Growth, the enforcement in Chongqing shows, the modified husky body of the high storage capacity obtained by regulation match ratio, Can rice cultivation flourishing, until gathering in the crops full Oryza glutinosa；Secondly, the evaporation characteristic of modified husky body Also similar with soil, after the evaporation of moisture in the grains of sand of surface, internal moisture not directly and extraneous contact, from Top to bottm slow evaporation, keeps a rational evaporation and water storage gradient.But, spray the surface formed thin Layer, the characteristic of its water conservation, water storage and evaporation and modification sand body fundamental difference, just spray and to reside in surface thin Water in Ceng, is only capable of penetrating into the scope that below top layer is the least, it is easy to evaporates and is formed and extraneous closing Solid film, now, thin film itself without storage capacity, its water storage principle is: utilize the free water in husky body Point, the complex process evaporate because temperature is uneven in temperature, condense, being hampered, finally make it rest under thin film Region near side, this water storage principle and soil and the water storage principle fundamental difference of modification sand body, storage Moisture is few, is only capable of the growth adapting to minority plant.

3rd, the plantation of plant is different with growth characteristics.

First, in the plantation characteristic of seed, implementing contrast and show, for modified husky body, seed can be embedded in In modified husky body, or being sown in modified husky surface, the germination characteristic according to seed is different, and various seeds are equal Can germinating growth；And for the method for surface sprinkling adhesion layer, after various seeds are buried or are broadcasted sowing, it is necessary to Spray thin layer and adhere to cover layer, but, owing to the moisture below surface coating is few, the seed being partly embedded into Do not germinate or germination is poor；Simultaneously as can close seed after surface coating solidification, (and moisture is Evaporation), the seed broadcasted sowing is after covering thin layer, and same appearance is not germinateed or the situation of germination difference.Therefore, Modified husky body has the character of soil, germination preferably.

In the plantation characteristic of plant, implementing contrast and show, modified husky body can plant various plant, according to The difference of modified husky body thickness, can plant the herbaceous plant that plant is short and small, it is possible to the grass that plantation plant is tall and big This plant, also can plant shrub, and, local thickness and volume at modified husky body can stablize plant roots In the case of system, also can plant high megaphanerophyte；But, form thin layer adhesion cover layer at spraying liquid after, Especially the evaporation of the moisture in thin layer cover layer and after forming solid thin-film layer, serike is to destroy thin film Layer is cost, therefore, after spraying thin layer cover layer, suitably plants any plant more hardly；And plant and plant Spray adhesion layer after thing again, be not much real value.

In the growth characteristics of plant, the universal well-grown of plant in modified husky body, there is no with general soil Difference, according to the difference of modified husky body thickness, modified husky body can be with the short and small herbaceous plant of growth plant, also Can the tall and big herbaceous plant of growth plant, also can grow shrub and arbor, but, only spray at thin layer and cover In the case of, the universal growing state of plant is poor, and, the sand below thin layer cover layer, it is difficult to firm Herbaceous plant (such as Semen Maydis etc.) that plant is tall and big and trees.

It should be noted that above example is only in order to illustrate technical scheme and unrestricted, although With reference to preferred embodiment, the present invention is described in detail, it will be understood by those within the art that, Technical scheme can be modified or equivalent, without deviating from technical solution of the present invention Objective and scope, it all should be contained in the middle of scope of the presently claimed invention.
