Beneficial effects of the present invention
Not only it is rich in Si, Ca, Fe, Mg and considerable amount of micro no element in the conditioner of the present invention, have higher absorption to live
Property, water absorption and porosity, heavy metal has absorption, passivation, can improve the retentiveness of soil, the pH of conditioning soil, changes
Good soil.And the content of organic matter of soil can be significantly improved, improve Soil structure, improve Water and fertilizer retention ability of soil, additionally,
While effectively stoping root system of plant Adsorption of Heavy Metals, the utilization ratio of soil N P, K can be improved, improve crop yield.No
Only such, the present invention also can reduce the acidity of soil and the toxicity of heavy metal on plants ,-COOH ,-COH and-OH that surface is enriched
The surface negative charge producing Deng oxygen-containing functional group can improve the sun of soil from exchange capacity, and the pore structure of height also can increase soil
The voidage of earth and water holding capacity, strengthen the carbon solidification effect of soil, can provide existence and breeding place for microorganism simultaneously.This
Outward, the conditioner of the present invention can with the heavy metal ion in soil generate the extremely low phosphate mineral of solubility product (during as 25 DEG C, phosphorus
The solubility product of sour cadmium is 2.53 × 10-33, the solubility product of lead phosphate is 8.0 × 10-43), in soil, the lead of various forms lures through phosphorus
After leading, it is changed into the higher lead phosphate of stability, reduces the effectiveness of lead；Crop yield also can be increased simultaneously, accelerate frumentum
Crop tiller, promotes young fringe differentiation, grouting and full seed, improves the resistance such as crop drought resistance, cold-resistant and salt resistance alkali.This
Bright conditioner has preferable absorption and ion-exchange performance, and heavy metal has certain adsorption effect.The amino that contains, hydroxyl
Base isopolarity group has alkalescence and hygroscopicity, plays the effect of absorption, ion exchange, chelating and acid-alkali accommodation.And it is adsorbable
Soil available heavy metal, especially cadmium, suppression heavy metal passes through transfer into plant body and in seed for the plant root；With
When, this conditioner also has reduction to the arsenic in soil, chromium, can reduce bio-toxicity in soil for the heavy metal.
