Description
Technical field
The present invention relates to a kind of soil conditioner and preparation method thereof, this fertilizer not only can improve soil physics structure by adjustment of acidity soil, can also prevent and treat the physiological disturbance that crop causes because of calcium deficiency, magnesium.
Background technology
Soil acidification mainly refers to the H in soil
+and Al
3+quantity increases, and causes the exhaustion in soil positively charged ion storehouse.Soil acidification is one of subject matter in global environmental change, and it makes, in soil system, a series of chemical processes occur and reverses, and then has influence on the whole ecosystem.
In South China Tropical, subtropical zone, exist a large amount of acid soils, comprising the yellow earth area in the Red earth zonal with Central China and south China and Sichuan, Guizhou and the Yunnan-Guizhou Plateau, the soil total area 2,180,000 km
2, accounting for 22.7% of the national soil total area, the pH of most of soil is less than 5.5, is wherein greatly less than 5.0, and even 4.5.In addition, the most of acid soil degree of base saturation of south China is lower, is 25% left and right, is in the scope that soil cushion effect is less, these factors make that south China big area is red, the sour cushion effect of yellow earth a little less than, easily there is acidifying.During southern dry land acidic soil raise crop, can destroy the saturating property of plasmalemma in certain plants body, cause reducing the absorption of farm crop to elements such as calcium, magnesium, potassium, Agricultural Output rate is lower.But it is wide that such soil distributes as agricultural land, and area is large, it is the important production base of the torrid zone, subtropics cash crop and forest, fruit tree.
Except natural acidic soil, also have a lot of human factors to cause soil acidification.
Irrational fertilizers input causes soil acidification phenomenon obvious.In recent years, various composite fertilizers use in a large number, and except topdressing on a small quantity with urea, most of base manure is composite fertilizer, and these composite fertilizers are mainly by calcium superphosphate, Repone K, and the physiological acidic fertilizers such as ferric sulfate are formulated.After the main nutrient elements such as N, P, K are absorbed by crops, residual lower SO in soil
4 2-, Cl
-deng acid group, impelled the acidification of soil.In addition, use fertilizer or the human excrement do not become thoroughly decomposed, become thoroughly decomposed with decomposition course in produce various organic acids, also accelerated the acidifying of soil.Simultaneously; some sulfide, nitrate and inorganic salt remain in soil; cause soil salinization; because mistress's gas communication in protection ground is restricted; in protection ground, oxygen is not enough; soil oxygen level declines, and the carbon dioxide build-up that root system is breathed out forms carbonic acid with water in soil, causes the increase of soil acidity.The total nutrient of wheat, corn, booth vegetable and fruit tree system drops into all the nutrient demand considerably beyond crop itself, a large amount of nutrients remains in soil profile, caused a series of Soil degradation problem that comprises soil acidification, salinification, wherein with intensive vegetable filed the most obvious with orchard soil acidifying phenomenon.
Long-term continuous cropping causes soil acidification.Xue Jicheng studies report, and along with the increase of the greenhouse gardening time limit, P in soil H reduces gradually.The investigation of the heliogreenhouse of Shouguang City, Li Junliang Deng Dui Shandong Province shows, the pH of greenhouse topsoil obviously reduces with the increase in canopy age.In Soil Development in Huaibei Plain, within 15 years, yellow moisture soil vegetable plot becomes neutrality from alkalescence gradually, and black ginger soil vegetable plot becomes acidity from neutrality.
Soil acidification will have a strong impact on crop-planting and ecotope.
Soil acidification will speed up the decline of soil acidity and the leaching loss of element, impoverishing the soil.Soil pH is too low except can directly causing H to crop
+outside murder by poisoning, soil, when its acidity improves, can make to increase active aluminum and some heavy metal element stripping quantity, thereby reduces crop product quality, even can cause that dunsiekte is dead when serious.In addition, soil base cations (Ca is accelerated in acidifying meeting
2+, Mg
2+, K
+, Na
+and NH
4 +) leaching loss, thereby cause the loss, soil physical property of soil nutrient pool to worsen, cause soil nutrient barren and reduce crop product quality.Soil also makes the activity of some heavy metal element increase when its acidity improves, and this causes because the toxic metal ions such as manganese, chromium, cadmium solubleness under low pH value raises.Soil peracid, can obviously affect the activity of Soil Microorganism, organic synthetic and decomposition, conversion and release, the validity of trace element and the ability of Soil conservation nutrient etc. of nutritive element, thereby affect the growth of ecological environment of soil quality and crop.
Improvement acidity and acidified soil are agriculture production problem demanding prompt solutions.Mugineic acid soil improvement agent, not only can regulate soil acidity or alkalinity, can also effectively improve soil physics structure, reduce the soil weight, change soil chemical properties, strengthen soil microbial activity, regulate the soil water, fertilizer, gas, thermal conditions, can impel the soil particle reunion of dispersion to form granule, increase content and the stability of water-stable granule in soil, improve ventilating permeable, finally reach the effect of increasing soil fertility.
