The invention also discloses the preparation method for the conditioner.
Description
Technical field
The present invention relates to agricultural and use new material technology field, mainly is soil improvement.More specifically, the present invention relates to a kind of water-soluble organic acid soil improvement agent compsn and preparation thereof and application.Described soil improvement agent compsn contains phytic acid, Sumizyme PHY, Citric Acid, amino acid, methylene-succinic acid and permeate agent, is particularly useful for the reparation and the improvement of obstacle property soil due to the acidifying.
Background technology
One, soil acidification
The large-area acid soil that distributing widely on the south China the Changjiang river mainly concentrates on southern provinces such as Zhejiang, Jiangxi, Fujian, Guangdong, Guangxi, Hainan, Yunnan and Guizhou, and the total area is about 200,000,000 hm
2The pH value of most of acid soil is less than 5.5, and wherein a big chunk is less than 5.0, even lower.And along with the further developing of Chinese society economy, China's acid soil area and soil acidification degree also have the trend that further increases.Professor Zhang Fusuo team of resource and environment institute of China Agricultural University finds from the research that the Chinese agricultural land soil pH value of past over more than 20 year changed; Acidifying phenomenon in various degree all takes place in the agricultural land soil up to 90%; Soil pH value about 0.5 unit that on average descends, being equivalent to soil acid amount has increased by 2.2 times on the original basis.Relevant paper " remarkable acidifying takes place in China main farmland " is published on the international top academic journals " science ".
The soil acidification aluminium toxicity is the ubiquitous serious agriculture prodn problem of worldwide, affects the crop production of the world's 40% cultivated area.Aluminium in the soil mainly exists with the form of stationary state, and the aluminium of this stationary state does not have toxic action to plant and environment, has only the aluminium of free state just can exert an influence to plant and environment.
In recent years, the serious day by day and a large amount of uses of acidic fertilizier in agriculture prodn of global range acid deposition have been quickened the release of aluminium in soil and the settling greatly, thereby have been influenced plant to nutrition and absorption of water.China south large-area acid soil that distributing accounts for 21% of the national soil total area, and the aluminium poison has become one of principal element that suppresses plant-growth in the acid soil.At present, the major measure of slowing down the harm of aluminium poison in the acid soil is a liming, improve pH in soil, but action time is short and cost is higher, also can produce as reducing the validity of soil phosphorus, zinc, causes soil compaction, detrimentally affects such as multiple acidifying.
Two, the reason of soil acidification? Natural cause and human factor:
Natural cause mainly contains:
1. the organic acid that produces of the decomposition of root system of plant activity and soil with organic matter and a large amount of CO
2, the mineral acid that also has certain micro-organisms to produce all is the H in the soil solution
+The source;
2. on soil colloid, adsorb H
+After reaching some amount, the lattice of clay-sized mineral is destroyed, and makes in the clay-sized mineral that aluminium is dissolved to come out, and has occurred active aluminum in the solution, discharges H after the hydrolysis
+
3. the H of colloid absorption
+And Al
3+Replaced in the solution and make soil be acid by other.
Human factor mainly is:
1. a large amount of dischargings of sour gas cause the increase of acid deposition.Be discharged into airborne SO
2And NOx.Some directly infiltrates the face of land and forms dry deposition, and another part forms strong acid H at last through a series of chemical reaction
2SO
4And HNO
3, rainwater pH value descends thereupon and forms acid rain.Soil acidification starts from active proton (H
+); Because hydrogen matter clay is unstable; After the hydrogen ion of soil organic mineral complex body or aluminosilicate clay-sized mineral surface adsorption reached certain limit, the crystalline network of these particles will be destroyed, and alumina octahedral can disintegrate; Be the constraint that aluminum ion has broken away from octahedra lattice, be transformed into the exchangeability aluminum ion.The hydrolysis of content of soil exchangeable aluminium makes soil show the acidity characteristic, according to the difference of hydrolysis degree, and (an Al
3+) hydrolysis can produce 1～3 H
+Hydrogen ion.The result causes loss and some toxic element of plough horizon giving property nutritive element (potassium, sodium, calcium, magnesium etc.), like disengaging and activation of heavy metal cadmium (Cd).
2. long-term excessive simple use chemical fertilizer makes soil acidification:
Such as ammonium sulfate [(NH
4)
2SO
4Its nutritious part is at the ammonium (NH of nitrogenous (N)
4 +) positively charged ion, then plant will absorb ammonium ion in a large number and not absorb nonnutritive sulfate ion (SO
4)
2-, a large amount of hydrogen ion (H that discharge in the ion exchange process that absorbs
+), cause soil acidification.
Soil acidification and harm:
1. behind the soil acidification, aluminiferously in the soil primaryly quicken with the secondary mineral weathering and discharge a large amount of aluminum ions, form the aluminum compound that plant can absorb form.The absorption aluminium that plant is excessive not only can reduce the crop product quality, also can cause the excessive absorption aluminium of plant (Al to particularly greatly influence of plant root growth generation of plant materials
+) be poisoned to death.
2. soil acidification also makes soil that the fixed action of phosphate radical and molybdate is strengthened, and the validity of soil phosphorus and molybdenum reduces, and is deposited in a large number to cause the poor ridgeization of soil compaction in the soil, influences plant normal growth and growth.
3. soil acidification also can cause the activation of toxic heavy metal element in the soil, not only influences plant growth, also can be through the health of food chain harmful to human or animal body.
4. soil acidification hardens influences the activity of soil microorganisms, and soil microorganisms quantity is reduced, and microbial growth and activity are suppressed, thereby influences the circulation of C, N, P, S in decomposition and the soil of the soil organism.
5. soil acidification pH is low is the important factor that influences the validity of phosphorus in the soil, and aggravation is to phosphorus fixation, and pH is between 5.5～7.5, and the validity of phosphorus is the highest.Acid soil often contains a large amount of Al
3+, Fe
2+And Mn
2+, they be prone to soil in phosphate anion be combined into insoluble phosphate, reduced the validity of phosphoric in the soil.Under the low pH edaphic condition, along with the reduction of soil cation exchange capacity (CEC), K
+Availability also reduce, thereby influence plant to K
+Absorption.
6. soil acidification is organic reduces, and soil bacteria and actinomycetes quantity are minimizing trend with the increase of the continuous cropping time limit, and fungi is minimum with continuous cropping 3 years; Continuous cropping has bacterium and fungi
Bacteria group quantity reduces, and the rotten mould pernicious bacteria quantity that waits increases.
Up to now, the ameliorative measure of soil acidification and the experience of accumulation there are the control sulfur dioxide emissions, agricultural and biological modification measure, chemical modifying measure etc. both at home and abroad.
Control sulfur dioxide emissions: at present we the country and countries in the world all in effort, the concrete measure of taking is:
(1) confirm rational acid deposition control region and sulfur dioxide emissions control region, control automotive emission amount:
(2) readjust the energy structure the development substitute energy.Exploitation can substitute coal-fired clean energy, like nuclear power, water power, sun power, wind energy, Geothermal energy etc.:
(3) promptly research and develop sulfurous gas and administer technology and equipment, optimize the ability source quality, improve energy utilization rate, reduce the sulfurous gas that burning produces:
It is to solve the people at present for causing aspect of sour factor that aforesaid method is implemented, and can not solve the conditioner for acidified soil problem due to acidifying and the other factors.
Agricultural and biological modification measure:
It mainly is to utilize some animals in green manure and the soil to reach the purpose that improves acidified soil that acid soil adopts the mikrobe improvement, on agricultural, utilizes organic materials improvement acid soil that the history in over thousands of year has been arranged.Use the nutrient that organic substance can not only provide crop to need in the soil, improve the fertility level of soil, can also increase the activity of soil microorganisms, increase the shock-absorbing capacity of soil, utilized the technology of biological modification acid.Organic materials can also be compound with monomer aluminium, reduces the content of content of soil exchangeable aluminium, alleviates the toxic action of aluminium to plant; Organic materials kind as improving the soil is a lot; It is also more convenient in agricultural, to draw materials, like the stem stalk of various farm crop, the muck of poultry, green manure and plant ash or the like.
Yet the effect of this agricultural improvement or biological modification receives the restriction of conditions such as improvement time soil acidification degree and raw material sources, is difficult to obtain ideal effect in a short time!
Chemical improvement agent
1. lime modifying agent:
Lime can sweetening of the soil the live acid and the acid of diving, generate precipitation of hydroxide, effectively reduce the acidity of acid soil rapidly, can also increase the content of exchangeable calcium in the soil.But the lime application method has only been handled topsoil, and the aluminum ion activity of subsoil does not still change, and deep rooted plant especially cereal class still can receive serious aluminium evil.
There is multiple acidization in soil behind the liming, and action time is short and cost is higher, and also can produce like the validity that reduces soil phosphorus, zinc is that acidifying takes place soil once more after the alkalescence consumption of lime, and acidizing degree than liming before aggravation to some extent.
2. the improvement of mineral and trade waste:
People had found again that some mineral substance and industrial by-products also can play the effect of improvement acid soil in recent years.As: trade wastes such as phosphogypsum, flyash, alkaline residue, ground phosphate rock and waste liquor contamination.The staple of phosphogypsum is a calcium sulfate, after soil and the calcium sulfate reaction, and SO
4 2-And OH
-Between the dentate exchange interaction produce basicity.The thin ash that flyash, the coal in fuel-burning power plant are collected by fly-ash separator behind high-temp combustion, the structure that granulates, mainly siliceous, aluminium, iron and trace element, the pH value between 10～12, CaO wherein, alkaline matters such as MgO, the acidic substance in can sweetening of the soil.
Aforesaid method all can be received certain effect.Slag, trade waste consumption large resource is limited, but some slags, trade waste might also contain the harmful element composition, can produce secondary harm.
The mechanism of action that common modifying agent is improved the soil is divided three kinds:
1. physical method alleviates artificial acidifying phenomenon.Promptly through fertilization compositions based on earth measurement, use chemical fertilizer scientifically and rationally, through executing physiological alkalinity or neutral fertilizer improves the soil physical chemistry situation.
2. during microorganism species (microbial-bacterial fertilizer) is manured into soil. let mikrobe bring into play biological effect; The improvement acidified soil reaches the purpose of improving the soil; Be the measure and the method for ideal improvement acidified soil, a lot of preparations occur on this produce market but practical application effect is undesirable.This and the soil acidification edatope that hardens is bad, and mikrobe is difficult to a large amount of breedings in bad environment, and limited reason plays a role.Want to reach better effect, should adopt better measure the physico-chemical property of acidified soil improve and repair, mikrobe has the such microorganism species of good living space to breed in a large number, just can reach ideal effect.
3. chemical process---be mainly used in and add alkali neutralization (chemical action), like lime: this repeatedly uses also can be created in multiple acidization.Phosphogypsum, flyash, alkaline residue, ground phosphate rock etc., these consumptions are big, and raw material can not satisfy large-scale production of agricultural to be used, and some slag also might contain harmful element and cause secondary pollution to soil.
One Chinese patent application number 200910018585.9 (2009.9.24 applications; Publication No. CN101665699A) a kind of nutrient conditioner for acidified soil in orchards and preparation method thereof and application are disclosed; He contains carbon CaCl2, light burnt powder, flyash, slag, common fused(calcium magnesium phosphorus)potash fertilizer etc. and is main improvement composition, these alkaline matter compositions acid soil acidity that can neutralize.Its deficiency is that consumption is big, repeatedly uses for a long time to produce the multiple acidization of soil, finally causes the soil acidification can be more and more serious, and secondary harm etc. takes place.
