Problems solved by technology

[0008] There are two main technical bottlenecks restricting the industry of soil improvement and restoration technology products. One is the destruction of the agricultural ecological environment, the imbalance of microorganisms in some soils, and the decline in self-healing ability. The application technology of soil improvement and restoration of beneficial microorganisms is far from satisfactory due to The adverse effects caused by the destruction of soil micro-ecology, and most of the microbial application technologies for soil improvement and restoration are still in the research stage, and few effective products have been formed; the second is that the fertilization technology is not matched with the fertilizer variety, and the fertilization technology is backward, resulting in a serious proportion of chemical fertilizers. Imbalance, chemical fertilizer input benefit drops significantly
In fertilization, there is a phenomenon that heavy macroelement fertilizers are light and medium trace element fertilizers, resulting in soil compaction, which is not conducive to crop absorption and utilization, and then causes soil environmental problems

Abstract

The invention relates to a biological repairing agent of soil. The biological repairing agent is prepared from bacillus cereus bacterium powder, pythium oligandrum bacterium powder, trichoderma viride bacterium powder, a sphingobacterium multivorum fermented product, mushroom dreg of edible mushrooms, calcium amino acid chelate, zinc amino acid chelate and DA-6; the biological repairing agent can be used for degrading pollution of petroleum agriculture and pesticide residues, and can be applied to a farmland so that the aims of ameliorating soil and preventing diseases, reducing the residues and promoting growth so as to improve the micro-ecological activity and self-repairing capability of the soil, increase the yield of crops, improve the quality and maintain the agricultural ecological health can be realized.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of agricultural microorganisms. More specifically, the present invention relates to a soil bioremediation agent. [0003] 【Background technique】 [0004] Soil is an important carrier and place for material transformation and energy exchange in agricultural production, and it is also the core part of the ecosystem. Among various environmental elements, soil is the final receptor of pollutants. With the widespread application of petroleum products and chemical pesticides on farmland, petroleum pollutants and pesticide residues left in the soil have become an urgent problem to be solved because they are difficult to eradicate. [0005] A series of outstanding problems caused by petroleum agriculture, such as the deterioration of the ecological environment, soil salinization and hardening, the proliferation of diseases and insect pests, serious white pollution, and the decline in the quality of agricult...
