Embodiment 1

[0024] A soil conditioner for remediating soil pollution is prepared by mixing the following raw materials in weight percentage: 1% of compound microbial bacterial agent, 60% of organic matter, 29% of medium and trace element soil conditioner, and 10% of macromolecular organic matter.

[0025] The compound microbial agent is a combined bacterial population of three strains of Bacillus licheniformis, including microbial pesticide fungicide BL-16 strain, microbial pesticide insecticide BL-8 strain, and natural plant growth regulator BL-3 strain, The three strains of Bacillus licheniformis came from biological preparations produced by Kaisheng Fertilizer Group.

[0026] The organic matter comes from generally decomposed and sterilized animal and plant residues, livestock and poultry manure, and cake fertilizer.

[0027] The proportion of the medium and trace element soil conditioner according to 100% of the total weight: 20-28% of silicon, 14-28% of calcium, 6-20% of magnesium, 2...

Embodiment 2

[0034] Embodiment 2: a kind of soil conditioner for remediating soil pollution, it is mixed by the raw material of following percentage by weight: composite microbial bacterial agent 2%, organic matter 65%, medium and trace element soil conditioner 25%, macromolecular organic matter 8 %.

[0035] The compound microbial agent is a combined bacterial population of three strains of Bacillus licheniformis, including microbial pesticide fungicide BL-16 strain, microbial pesticide insecticide BL-8 strain, and natural plant growth regulator BL-3 strain, The three strains of Bacillus licheniformis came from biological preparations produced by Kaisheng Fertilizer Group.

[0036] The organic matter comes from generally decomposed and sterilized animal and plant residues, livestock and poultry manure, and cake fertilizer.

[0037] The proportion of the medium and trace element soil conditioner according to 100% of the total weight: 20-28% of silicon, 14-28% of calcium, 6-20% of magnesiu...

Abstract

The invention provides a soil conditioner for repairing polluted soil. The soil conditioner is prepared by mixing the following raw materials in percentage by weight: 1-2.5% of a compound microorganism agent, 60-75% of an organic matter, 25-45% of a medium trace element soil conditioner and 5-20% of a macromolecular organic compound, wherein the macromolecular organic compound consists of poly gamma-glutamic acid and humic acid; and humic acid comes from high-quality lignite. The soil conditioner provided by the invention has the effects of improving soil, degrading soil pesticides and residual fertilizers, passivating and fixing farmland heavy metals, reducing adsorption of plants to heavy metals and improving the crop yield and quality, is used for repairing and controlling farmland pollution, and has such remarkable functions of fertilizer supply, soil improvement, soil-ripening progress acceleration, and crop yield and quality improvement.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a soil conditioner for remediating soil pollution. Background technique [0002] At present, the overall situation of soil pollution in China is quite severe. In December 2013, the Ministry of Environmental Protection and the Ministry of Land and Resources conducted the first large-scale and large-scale survey on the country's soil pollution situation. According to the final survey results, the following conclusions can be drawn : my country's current soil environment situation is already very severe, and various regions are facing different degrees of soil problems, and the situation in some regions is particularly prominent. According to statistical data, the total point exceeding standard rate of soil in my country is 16.1%. From the perspective of soil use types, the corresponding point exceeding rates of various types of land in my country at this stage are: 20.4% for cultivated land soi...
