Abstract
The invention provides a soil additive for controlling heavy metal accumulation of a crop and a preparation method thereof. The soil additive is prepared from the following components in parts by weight: 1-10 parts of phosphate compounds, 3-15 parts of calcium hydroxide, 2-6 parts of potassium sulphide, 1-10 parts of magnesium-containing preparations, 1-3 parts of cationic surface active agents, 45-55 parts of organic materials and 2-5 parts of biologically compound fertilizer. The preparation method comprises the following steps: mixing the organic material with the biologically compound fertilizer to form a mixture A, mixing the rest components according to the weight part to form a mixture B, and separately storing the mixture A and the mixture B. In use, the mixture A and the mixture B are mixed according to a specified proportion, and then are uniformly mixed with heavy metal polluted soil according to a ratio of 1 : (25-35). The soil additive for controlling the heavy metal accumulation of the crop has the advantages that the heavy metal content of a soil solution can be reduced, the absorption of crop roots to water and nutrition is facilitated, the absorption of the crop roots to the heavy metal is reduced, and the problem that the human life health is threatened because the heavy metal is accumulated in the crop and enters the food chain is avoided.
Description
Technical field:
The present invention relates to soil remediation field, particularly a kind ofly control soil additive of crop Accumulation of heavy metals and preparation method thereof.
Background technology:
At present, heavy metal pollution of soil has become great safety problem.Cause the reason of heavy metal contamination very many, the fields such as mainly mining, Metal smelting, electroplating industry, chemical industry, intermetallic composite coating, IT industry and waste electrical equipment recovery produce and discharge heavy metal contaminants, enter after in surface water, underground water and air, these heavy metals finally come together in soil.These toxic heavy metals excess accumulation in food, and then enter food chain, serious threat HUMAN HEALTH.
Therefore, being reduced by various agronomic measures and controlling soil available cadmium, lead and mercury is study hotspot problem both domestic and external always, but have not yet to see scale operation and be applied to heavy metal-polluted soil reparation and satisfactory for result, with low cost, there is the additive of application value.
Summary of the invention
The object of the present invention is to provide a kind of soil additive controlling crop Accumulation of heavy metals, the heavy metal content in the soil solution can be reduced, prevent heavy metal from accumulating in crop and enter food chain.
Control a soil additive for crop Accumulation of heavy metals, obtained by the component of following weight part: phosphate compound 1 ~ 10 part, 3 ~ 15 parts, calcium hydroxide, potassium sulphide 2 ~ 6 parts, containing magnesium preparation 1 ~ 10 part, cats product 1 ~ 3 part, organic materials 45 ~ 55 parts, compound bacterial fertilizer 2 ~ 5 parts.
Described phosphate compound is draw together one or more in potassium hydrogen phosphate, secondary calcium phosphate, potassium primary phosphate.
Described is one or more in magnesium sulfate, magnesium oxide, magnesium chloride containing magnesium preparation.
Described cats product is diethanolamine.
Described organic materials is one or more in rapeseed cake, soybean cake, dregs of beans or weeds stalk.
Described compound bacterial fertilizer is the microbial-bacterial fertilizer containing boron.
A preparation method for the soil additive of above-mentioned control crop Accumulation of heavy metals, comprises the following steps:
(1) by phosphate compound, calcium hydroxide, potassium sulphide, containing magnesium preparation, cats product, organic materials and compound bacterial fertilizer, pulverize;
(2) organic materials processed through step (1) and compound bacterial fertilizer are proportionally mixed, make mixture A;
(3) by the phosphate compound processed through step (1), calcium hydroxide, potassium sulphide, proportionally mix containing magnesium preparation and cats product, mixture B is made;
(4) when using, AB is mixed in proportion, stirs according to 1:25 ~ 35 with the soil of heavy metal contamination.
Beneficial effect of the present invention is: the soil additive of control crop Accumulation of heavy metals of the present invention can reduce the heavy metal content in the soil solution, promote that crop root is to the absorption of moisture and nutrition, reduce the absorption of root system heavy metal, prevent heavy metal from accumulating in crop and enter food chain, threaten human life healthy.The requirement of China " standard of soil environment quality " (GB 15618-1995) secondary standard value is met after soil remediation.
