The acid soil conditioner composition contains organic raw materials, namely phytic acid, phytase, citric acid, amino acid and itaconic acid. The acidified soil conditioner composition is especially suitable for ecologically conditioning and restoring obstacle acidified soil caused by acid rain or improper fertilizer for a long term. The invention also discloses the preparation method for the conditioner.
Description
Technical field
The present invention relates to agricultural new material technology field, mainly soil improvement.More specifically, the present invention relates to a kind of water-soluble organic acid soil improvement agent composition and preparation and application thereof.Described soil improvement agent composition contains phytic acid, phytase, Citric Acid, amino acid, methylene-succinic acid and permeate agent, is particularly useful for reparation and the improvement of dyskinetic soil caused by acidifying.
Background technology
One, soil acidification
Be dispersed with large-area acid soil widely on the south China the Changjiang river, mainly concentrate on the southern provinces such as Zhejiang, Jiangxi, Fujian, Guangdong, Guangxi, Hainan, Yunnan and Guizhou, the total area is about 200,000,000 hm
2.The pH value of major part acid soil is less than 5.5, is wherein less than 5.0 greatly, even lower.And further developing along with Chinese society economy, China's acid soil area and soil acidification degree also have the trend increased further.Professor Zhang Fusuo team of College of Resources and Environmental Sciences, China Agricultural University finds from the research to the Farmland in China changes of pH of past over more than 20 year, all there is acidification phenomenon in various degree in the agricultural land soil up to 90%, soil pH value on average declines about 0.5 unit, is equivalent to soil acid amount and adds 2.2 times on the original basis.Correlative theses " remarkable acidifying occurs in China main farmland " is published on international top academic journals " science ".
Soil acidification aluminium toxicity is the ubiquitous serious agriculture production problem of worldwide, affects the crop production of Century Square 0% cultivated area.Aluminium in 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, only has the aluminium of free state just can to plant and environmental effects.
In recent years, the day by day serious and a large amount of uses of acidic fertilizier in agriculture production of global range acid deposition, greatly accelerate the release of aluminium in soils and sediments, thus affect the absorption of Plant To Nutrient and moisture.South China is dispersed with large-area acid soil, accounts for 21% of the national soil total area, and aluminium poison has become one of principal element suppressing plant-growth in acid soil.At present, the major measure slowing down the harm of aluminium poison in acid soil is liming, improves the pH value of soil, but action time is short and cost is higher, also producing the validity as reduced soil phosphorus, zinc, causing soil compaction, the detrimentally affects such as multiple acidifying.
Two, the reason natural cause of soil acidification and human factor:
Natural cause mainly contains:
1. the organic acid that produces of root system of plant decomposition that is movable and soil with organic matter and a large amount of CO
2, the mineral acid also having certain micro-organisms to produce is all the H in the soil solution
+source;
2. when soil colloid adsorbs H
+after reaching some amount, the lattice of clay-sized mineral is destroyed, and aluminium in clay-sized mineral is dissolved out, has occurred active aluminum, discharge H after hydrolysis in solution
+;
3. the H of colloid absorption
+and Al
3+in solution, soil is made to be acid by other displacements.
Human factor is mainly:
1. a large amount of discharges of sour gas, cause the increase of acid deposition.Be discharged into the SO in air
2and NOx.Some directly infiltrates earth's surface and forms dry deposition, and another part finally forms strong acid H through a series of chemical reaction
2sO
4and HNO
3, rainwater pH value declines formation acid rain thereupon.Soil acidification starts from active proton (H
+), because hydrogen matter clay is unstable, after the hydrogen ion of soilorgano mineral complex or aluminosilicate clay-sized mineral surface adsorption reaches certain limit, the crystalline network of these particles will be destroyed, alumina octahedral can disintegrate, be that aluminum ion has departed from the constraint of octahedra lattice, be transformed into exchangeable aluminum ion.The hydrolysis of rock picker makes soil show acidity feature, according to the difference of hydrolysis degree, and (an Al
3+) hydrolysis can produce 1 ~ 3 H
+hydrogen ion.Result causes plough horizon to the loss of property nutritive element (potassium, sodium, calcium, magnesium etc.) and some toxic element, disengaging and activating as heavy metal cadmium (Cd).
2. long-term excessive use chemical fertilizer merely makes soil acidification:
Such as ammonium sulfate [(NH

2sO
4its nutritious part is at the ammonium (NH of nitrogenous (N)
4 +) positively charged ion, then plant does not absorb nonnutritive sulfate ion (SO by absorbing ammonium ion in a large number
4)
2-, in the ion exchange process absorbed, discharge hydrogen ion (H in a large number
+), cause soil acidification.
Soil acidification and harm:
1. after soil acidification, accelerate containing the primary and secondary mineral weathering of aluminium in soil and discharge a large amount of aluminum ion, forming the aluminum compound of plant available form.The absorption aluminium that plant is excessive, not only can reduce crop product quality, also to plant materials particularly plant root growth generation extreme influence, can cause plant excessive consumption aluminium (Al
+) be poisoned to death.
2. soil acidification also makes the fixed action of soil to phosphate radical and molybdate strengthen, and the validity of soil phosphorus and molybdenum reduces, and is deposited in a large number in soil and causes the poor ridge of soil compaction, affect plant normal growth and growth.
3. soil acidification also can cause the activation of toxic heavy-metal elements in soil, not only affects plant growth, also can pass through the health of food chain harmful to human or animal body.
4. soil acidification hardens affects the activity of soil microorganisms, and soil microbe quantity is reduced, and microbial growth and activity are suppressed, thus affects the circulation of C, N, P, S in the decomposition of the soil organism and soil.
5. soil acidification pH is low is the important factor of the validity affecting Soil Phosphorus, and aggravate phosphorus fixation, pH is between 5.5 ~ 7.5, and P availability is the highest.Acid soil is often containing a large amount of Al
3+, Fe
2+and Mn
2+, their phosphate anions easily and in soil are combined into insoluble phosphate, reduce the validity of Soil Phosphorus element.Under low pH edaphic condition, along with the reduction of soil cation exchange capacity (CEC), K
+availability also reduce, thus affect plant to K
+absorption.
6. soil acidification organic matter reduces, and soil bacteria and Population of Actinomycetes are with the increase of the continuous cropping time limit in minimizing trend, and fungi is minimum with continuous cropping 3 years; Continuous cropping makes bacterium and fungi have
Bacteria group quantity reduces, and the rotten mould pernicious bacteria quantity that waits increases.
Up to now, there are control sulfur dioxide emissions to the ameliorative measure of soil acidification and the experience of accumulation both at home and abroad, agricultural and biological modification measure, chemical modifying measure etc.
Control sulfur dioxide emissions: at present we country and countries in the world all in effort, the concrete measure taked is:
(1) determine rational acid deposition control region and sulfur dioxide emissions control region, control automotive emission amount:
(2) readjust the energy structure, development substitute energy.Exploitation can substitute coal-fired clean energy, as nuclear power, water power, sun power, wind energy, Geothermal energy etc.:
(3) promptly research and develop sulfurous gas Treatment process and equipment, optimize energy quality, improve energy utilization rate, reduce the sulfurous gas of burning generation:
It is solve people at present for causing sour factor aspect that aforesaid method is implemented, and can not solve the conditioner for acidified soil problem caused by acidifying and other factors.
Agricultural and biological modification measure:
Acid soil adopts microorganism improvement mainly to utilize some animals in green manure and soil to reach the object of improvement acidified soil, improves agriculturally utilizing organic materials the history that acid soil has had over thousands of year.Use the nutrient that organic substance can not only provide crop to need in soil, improve the fertility level of soil, the activity of soil microorganisms can also be increased, increase soil to the shock-absorbing capacity of acid, make use of the technology of biological modification.Organic materials can also with monomer aluminium compound, reduce the content of rock picker, alleviate the toxic action of aluminium to plant, the organic materials kind being used as improvement soil is a lot, draw materials in agricultural also more convenient, as the stem stalk of various farm crop, the muck of poultry, green manure and plant ash etc.
But the effect of this agricultural improvement or biological modification is subject to the restriction of the conditions such as improvement time soil acidification degree and raw material sources, be difficult in a short time obtain ideal effect!
Chemical improvement agent
1. lime improvement agent:
Lime can sweetening of the soil active acid and dive acid, generate precipitation of hydroxide, effectively reduce rapidly the acidity of acid soil, the content of exchangeable calcium in soil can also be increased.But lime application method has only processed topsoil, the aluminum ion activity of subsoil has not still changed, and deep rooted plant especially Cereal still can be subject to serious aluminium evil.
After liming there is multiple acidization in soil, and action time is short and cost is higher, also can produce as after reduction soil phosphorus, the validity of zinc and the alkalescence consumption of lime, soil again acidifying occurs, and acidizing degree aggravates to some extent than before liming.
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: the trade wastes such as phosphogypsum, flyash, alkaline residue, ground phosphate rock and waste liquor contamination.The main component of phosphogypsum is calcium sulfate, after soil and calcium sulfate react, and SO
4 2-and OH
-between dentate exchange interaction produce basicity.Flyash, the thin ash that the coal in fuel-burning power plant is collected by fly-ash separator after high-temp combustion, granulate structure, mainly siliceous, aluminium, iron and trace element, and pH value is between 10 ~ 12, and CaO wherein, the alkaline matters such as MgO, can acidic substance in sweetening of the soil.
Aforesaid method all can receive certain effect.Slag, trade waste consumption large resource is limited, but some slags, trade waste likely also containing harmful element composition, can produce secondary harm.
The mechanism of action of common modifying agent improvement soil divides three kinds:
1. physical method alleviates the phenomenon that people is acidifying.Namely by fertilization compositions based on earth measurement, chemical fertilizer is used scientifically and rationally, by executing physiological alkalinity or neutral fertilizer improves soil physical chemistry situation.
2. during microorganism species (microbial-bacterial fertilizer) is manured into soil. allow microorganism play biological effect, improvement acidified soil reaches the object of improvement soil, be the measures and methods of desirable improvement acidified soil, a lot of preparation appear in this produce market but practical application effect is undesirable.This and the soil acidification edatope that hardens is bad, and microorganism is difficult to amount reproduction in bad environment, and play a role limited reason.Want to reach better effect, better measure should be adopted the physico-chemical property of acidified soil to be carried out improving and repairing, and microorganism has the such microorganism species amount reproduction of good living space, just can reach ideal effect.
3. chemical process---be mainly used in adding alkali neutralization (chemical action), as lime: this repeatedly uses and also can produce in multiple acidization.Phosphogypsum, flyash, alkaline residue, ground phosphate rock etc., these consumptions are large, and raw material can not meet the large-scale production and application of agricultural, and some slag also likely causes secondary pollution containing harmful element to soil.
(2009.9.24 applies for Chinese Patent Application No. 200910018585.9, publication No. CN101665699A) disclose a kind of nutrient conditioner for acidified soil in orchards and preparation method thereof and application, he contains carbon CaCl2, light burnt powder, flyash, slag, common fused(calcium magnesium phosphorus)potash fertilizer etc. for mainly to improve composition, and these alkaline matter compositions can neutralize acid soil acidity.Its deficiency is that consumption is large, and repeatedly use can produce the multiple acidization of soil for a long time, finally causes soil acidification more and more seriously, secondary harm etc. can occur.
