Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality Execute example, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only used To explain the present invention, it is not intended to limit the present invention.
The purpose of the present invention essentially consist in propose a kind of relatively low based on natural material and cost, protect beach preventing Engineering backfill soil will not produce the interim anti-washing structure of impact to the growth promoter of emergent aquactic plant while washing away, takes off Show the impact on original inhabitants' emergent aquactic plant growth promoter of the different base condition, and the embedded type proposing economical and efficient is ecological Gu beach technology, with solve that original ecology solid beach technology exists to be weak to flood erosion, cursive script the most long-time It is submerged in the problem that beach body under water is difficult to survive.The technical scheme is that for waterway regulation works Ecology solid beach technology: (1) according to variety classes vegetation energy for growth, resistance to flood characteristic and root system solid soil energy thereof Power, determines that applicable native breed, as solid beach vegetation, builds suitable raw Vegetative restoration pattern;
(2) according to the erosion control effect under anti-washing structure difference arrangement, design based on natural material and cost relatively Low interim anti-washing structure, selects suitable soil as shoal protection works backfill soil, it is proposed that a set of economical and efficient Embedded type ecology solid beach technology.
The detailed description of the invention of the selection wherein consolidating beach vegetation is as follows:
(1) suitable raw vegetation and plant species
Carry out ecological Gu Tan, first have to select beach vegetation the most admittedly.Below Gu the selection of beach vegetation should meet Principle:
1. adaptability principle: Gu beach vegetation is as building the biocenological pioneer of beach, it has to be possible to very well Adaptation local environment, resistance to flood, resistant, resistance to erosion, drought resistance to be got well, vitality is strong, can be at barren environment Lower survival.
2. local principle: should pay the utmost attention to local endemic species, avoids introducing alien species as far as possible, in case raw The generation of thing intrusion event, protection bio-diversity and ecological safety.
Purification property principle the most by force: pay the utmost attention to purify the species of local environment, the procreation for other species is created Suitable habitat.
4. operability principle: selected species need well developed root system, solid soil is effective, fertility strong, cultivation pipe Reason low cost, results are convenient, flood after be prone to recover, ecoscape is respond well, do not affect shipping and flood passage Safety, has certain economic use value simultaneously.
5. consolidating the selection of beach species it is also contemplated that the spatial and temporal distributions of vegetation, between different plant species, collocation is good, accomplishes season Joint alternates and covers, and spatial level is clearly demarcated.
The kiln of falling mouth channel bar, floods in environment from the foregoing it will be appreciated that the kiln of falling mouth channel bar is in seasonality, has 1-2 every year The time of individual month is affected by water channel water level, and channel bar is partly or completely submerged under water, therefore, selects species A major criterion be that these species have a preferable waterlogging resistance to ability of flooding, the waterflooding environment of favorable season, for This, humidogene species are only the plant species in suitably this region, and selected species must be at humidogene environment Middle survival.Secondly, the kiln of falling mouth channel bar most of the time exposure in atmosphere, belongs to terrestrial habitat, the especially heart Beach is domatic, and in 1 year, the most of the time is in drying regime, and therefore, the species of selection need can be at dry soil Middle survival and growth, have good drought-resistance ability.
Similarly, since substrate is barren, species are needed to have stronger vitality and adapt to the ability in barren habitat; In view of the ecological hazard of invasive species, needing to stop to introduce alien species, thus, the range of choice of species is required It is confined to the endemic species of the Yangtze river basin, it is possible to be well adapted to the environmental weather conditions of locality.
In addition, it is contemplated that the four seasons of species alternate and stratification of landscapes, the ecological functions of vegetation normally play, species Selection can not be the most single, need to consider the collocation of several species, it is ensured that species spatially have levels, Change in change of seasons.
According to above principle, through Comprehensive Correlation, select Bermuda grass, Herba Trifolii Pratentis and three kinds of eciophyte conducts of phragmites communis Gu beach species.
(2) solid beach vegetation breeds and manages
After determining solid beach vegetation, also need to guarantee that it survives.In view of the kiln of falling mouth channel bar current top layer alluvial basic Being chiltern coarse granule, particle diameter is big, and nutrition is barren, and sticking to each other property is poor, cause it possess certain mobility with Unstability;Therefore, the first problem that suitable raw revegetation needs solution is exactly the improvement of soil matrix;As Fruit does not change the physicochemical character of substrate, and vegetation lacks necessary soil, it is difficult to survive.Faced by base material improvement needs Two problems: one is stability, the channel bar being in seasonal silting and erosion must solve stablizing of soil matrix Sex chromosome mosaicism just may insure that the existence of plant is bred, if soil matrix is always in upheaval variation, and plant species Son is sprouted and vital metabolic cannot obtain necessary suitable external environment, and the structure of vegetation is impossible. Two is nutrition and moisture supply, and the barrenst and dry soil is for the growth promoter of plant and vital metabolic mistake Journey is that one is coerced and hinders, and current channel bar matrix nutrition is barren, it is difficult to meet the needs of plant growing, moisture , there is seasonal deficiency in supply respect, is also the problem needing to consider.
Beach range of stage is big, change is fast, and it is pressed for time, and different plant is to growing environment requirement for plant cultivating Difference, needs to take suitable breeding and management means, to improve survival rate.
For guaranteeing surviving of solid beach vegetation, it is necessary first to soil is carried out base material improvement, specific operation process is as follows:
1. gather materials on the spot, the ground picks such as neighbouring farmland, forest land are taken clay and is transported to Project Areas;
2. implant clay and tamp, implanting soil thickness and be advisable with 50cm;
3. periodically applications of farmyard manure provides required nutrient for plant, improves the soil texture, recommended rate of fertilizer application simultaneously 500kg/ mu;
4. large-scale inoculation soil algae algae kind, to increase substrate vigor.After inoculation next day start every day watering with Guarantee soil algae activity and play a role.
Three kinds of solid beach plants are respectively adopted different mating systems, and wherein Bermuda grass and phragmites communis use Split-Root Nutrient Solution Method in situ, Herba Trifolii Pratentis uses seeding method, specifically comprises the following steps that
Split-Root Nutrient Solution Method in situ: collect Bermuda grass stem and phragmites communis tuber, knock out earth, uniformly sow, soil layer covers also Compacting, variable interval is watered to keep moistening, can be rooted, within about 20 days, can grow and newly crawl in a few days Flagellum, slightly enriches nitrogenous rich water and prunes simultaneously, and stolon spreads rapidly and takes root, and forms planting quilt.
Planting density: Bermuda grass covers whole Project Areas topsoil, and stolon is cut into the segment of 3~5cm Sow, density 200~300g/m2;Phragmites communis is cut into 30cm mono-section, according to 6 sections/m2Density plantation;Three Leaf grass 200g/m2
Spatial distribution: being divided into two test block by physical features height, lower broadcasts sowing Bermuda grass, and eminence broadcasts sowing SANYE Grass.Bermuda grass vitality is relatively strong, and the space occupied is trefoil twice, and need not manual intervention two species Species structure.Under not blocking Bermuda grass and the Herba Trifolii Pratentis demand premise to illumination, determine that phragmites communis plants density It is 6 sections/m2
Plant field planting: for slowing down impulsive force, in initial planting, need to build the interim erosion control facility of necessity, will Plant growing, in the grid that straw rope weaves, reduces the current impact to plant by implantable straw rope structure;With Time, use modes such as beating timber, pressure stone, braiding bamboo fence to fix plant, in order to avoid plant lodging, it is ensured that become Motility rate.
Vegetation management: the management after plantation is the most important, is not added with management or management is the most extensive, before often causing Merit is abandoned to the greatest extent.Basic maintenance management work is extremely important, such as:
1. dress seed with pesticide with the seed protecting not earthing or the seedling being just unearthed in advance;
The most periodically water, suitably apply fertilizer;
3. the existence for other plants suitably gives protection and management, it is ensured that Plant Diversity;
4. people and animals' interference is taken precautions against, according to suitably pruning season;
5. the prevention and control of plant diseases, pest control is noted;
6. carry out management record, understand the growth characteristics of plant.
Specific to specified plant, then need different concrete management and maintenance methods.
1. the maintenance management of Bermuda grass, mainly includes pruning, irrigates, applies fertilizer and the prevention and control of plant diseases, pest control.
Prune: prune Controllable growth height, keep smooth attractive in appearance, increase density, may also suppress because of branch and leaf mistake Close and the disease that causes.Before pruning, remove clean foreign material, in order to avoid damage grass mower.Pruning frequency mainly depends on In the speed of growth of Bermuda grass, the most annual 2~3 times.Cutting range follows 1/3 principle.
Irrigate: Bermuda grass Root Distribution is the most shallower, should irrigate in time during drought in summer, disposably to fill during filling Thoroughly, not may occur in which water by the waist, make root system be distributed to top layer, reduce its drought resisting, solid soil ability.Irrigation quantity, filling Irrigate number of times depending on concrete condition.
Fertilising: apply fertilizer and provide desired nutritional material into Bermuda grass, is affect Bermuda grass resistance and quality main One of factor.Executing N spring fertile, the autumn in summer executes P, K, dose 250~300kg/hm more more2.Fertilising, filling Irrigate and combine, make fertilizer fully dissolve, it is simple to absorb, improve the utilization rate of fertilizer.
The prevention and control of plant diseases, pest control: prune in time, improves ventilation and penetrating light performance, and removes broken grass in time;Scientific and reasonable execute Fertilizer, improves diseases and insect pests resistance;Spray wide-spectrum bactericide and chrysanthemum lipid insecticide in time, both can prevent from having occurred Pest and disease damage spread, can prevent again.
2. the maintenance management of phragmites communis mainly include irrigation, thinning, transplant, apply fertilizer and disease pest and weed preventing and treating.
Irrigate: phragmites communis irrigates the irrigation program following " spring shallow, Xia Shen, Qiu Luogan ".
Fill shallow water before germinateing spring, improve ground temperature, accelerate soil and thaw, promote that phragmites communis germinates;After soil thaws Draining, keeps ground moistening;Phragmites communis germinates and after growth, fills shallow water 5cm.After mid-May, phragmites communis enters Entering peak of growing season, growth is accelerated, is needed water to increase, therefore take Deep irrigation, the deep 30-50cm of water layer.In 8 months After ten days, phragmites communis enters reproductive stage, and water requirement reduces, and need to carry out draining, only maintain ground moistening, with Promote phragmites communis ripe and autumn bud is grown.
Thinning: thinning when seedling height reaches 5cm, Seedling spacing 2cm.With the growth of seedling, timely thinning and removing Grass, and strengthen irrigation fertilization.
Transplant: when condition is suitable, when or reaching more than 5 DEG C at Second Year spring temperature after 7-8 month phragmites communis tiller Transplant.Transplant field is poured water holding ground moistening, is tripped out from nursery Tanaka by phragmites communis Seedling (before germination) and plants Plant, each 1m of seeding row spacing, the 3-5 strain of every cave.
Fertilising: the rational application of fertilizer, keeps soil nutrient balance, is promotion phragmites communis growth, improves the weight of reed pests Want factor.Therefore, the mid or late May in phragmites communis peak of growing season applies fertilizer.Apply fertilizer and should be noted following item:
One, middle low yield reed field yield potential is big, is fertilising emphasis;
Two, based on nitrogenous fertilizer, phosphorus potash fertilizer, dose 300-375kg/hm are coordinated2
Three, fertilising need to consider reed field character, is equipped with good job facilities, designs Optimum Irrigation system, makes water Fertile fusion, it is simple to phragmites communis absorbs;
Four, to saline and alkaline heavy, plot that crop smothering is many, first reduce soil salt content and prevent and kill off crop smothering, it is to avoid fertilizer Loss;
Five, soil testing and fertilizer recommendation, reduces fertilizer waste.
Disease pest and weed is prevented and treated: phragmites communis insect pest mainly has aphid, Locusta migratoria manilensis (Meyen) etc..Preventing and treating phragmites communis insect pest, first has to It is predicted forecast, determines Control stage;Two are in compliance with the principle that spot film preventing and treating combines with keypoint control, keep away Exempt from the waste of personnel and medicine.The insect pest serious time is sprayed with 800-1500 times of liquid of 40% omethoate.
Phragmites communis crop smothering mainly includes the Da Shi stem or leaf of cattail, the narrow leaf stem or leaf of cattail, sedge etc., should be according to grass veriety and biology Characteristic carries out science targetedly and prevents and kill off, and the method for control is as follows:
One, biological insect control and chemical control combine.
Two, a situation arises for investigation crop smothering, spot film the to be carried out preventing and treating of emphasis plot.
Three, spray insecticide it is noted that prevent the murder by poisoning to weeds surrounding plants and phragmites communis.
The most trefoil maintenance management mainly includes irrigating and the prevention and control of plant diseases, pest control.
Irrigate: before emerging, the carrying out being provided with spray irrigation system is sprayed, and does not has spray irrigation system, can make shower nozzle by oneself, Artificial spray is watered.Every morning or the most each sprinkling once, make bed surface, level ground remain moistening, until going out Seedling.Water spray number of times can be reduced after emerging, but still need to manage with delicacy.Seedling management about 30~50d, period notes Water and make level ground bed keep moistening.
Disease pest and weed is prevented and treated: after planting, uses at any time and manually pulls out method removing weeds.Level ground for Summer-sowing Bed, with Caulis et Folium Oryzae or Wheat-straw mulching, both can avoid high temperature damage, can make again level ground bed moisturizing.Treat that true leaf grows to cover During lid ground, when taking advantage of sky the moon or dusk, covering is thrown off.
(3) interim anti-washing structure
Initial planting, for avoiding plant seed or seedling to be taken away by current scour, need to arrange certain in test block Interim erosion control facility, to guarantee that vegetation field planting is taken root.Interim anti-washing structure need to meet two conditions: one is stronger Shock-absorbing capacity, do not reach full growth at vegetation root system, the period not possessing solid beach ability can sustain current Washing away, two is advantage of lower cost.
Cohesive sediment content is bigger on the impact of soil initial velocity.The soil that cohesive sediment content is more, granule Between cohesive force bigger, it is bigger to start the flow velocity that substantially washes away, and under equal conditions, scour depth is less.Consider Engineering is actual, usual consolidation process the most for some time after soil body backfill, and degree of compaction can increased, therefore real The backfill soil nature matter on border is close to cohesive soil.
Consider above-mentioned factor, select degradable straw rope to be laid to grid framework, use batten piling to carry out Fixing, as interim anti-washing structure.
The shock-absorbing capacity of the interim anti-washing structure of different types is different, and under equal conditions, anti-washing structure space is the biggest, Erosion control effect is the least.
Different vegetation growths there is also difference to the demand in space, when laying interim anti-washing structure, it is considered to this structure Space hold situation and impact on plant.In the technical program, Bermuda grass, Herba Trifolii Pratentis are the most closely Table, anti-washing structure impact is little, is not required to consider pitch problems.The plantation of general phragmites communis is spaced about 30cm, Straw rope is overstocked is inconvenient to plant, and need to consider pitch problems.
Consider the growing space demand of plant, the operability of plantation and the economy of interim anti-washing structure And service life, determine select diameter 1cm, rope spacing 10cm straw rope as interim anti-washing structure main body.
The solid beach works very well of ecology solid beach technology, uses this technology, and root surface area density (RSAD) can be Increasing from zero to more than 80 in 1 year, root weight density (RWD) in 30cm topsoil then can reach 670-1500g/m3。
It should be appreciated that the above, the only detailed description of the invention of the present invention, but the protection model of the present invention Enclosing and be not limited thereto, any those of ordinary skill in the art, can in the technical scope that disclosed herein The change readily occurred in or replacement, all should contain within protection scope of the present invention.
