Biological organic repairing agent for soil pollution and application and preparation method thereof

Abstract

The invention relates to the field of soil fertilizer and provides a biological organic repairing agent for soil pollution and its application and preparation method. The biological organic repairing agent of the invention is composed of, by weight, 1.5-3 parts of eymogenic bacterium, 1-1.5 parts of wheat bran, 1.5-2 parts of molasses meal, 45-50 parts of ammonium humate, 45-50 parts of hydrolase dregs, 150-200 parts of soybean meal, 100-150 parts of humic acid powder, 80-100 parts of zeolite powder, 25-40 parts of a calcium magnesium phosphate fertilizer, 150-200 parts of cattle and sheep manure, 150-204 parts of plant straw, 25-40 parts of potassium humate, 1.5-3 parts of bacillus mucilaginosus, 1-1.5 parts of Gliocladium roseum, 1.5-2 parts of Streptomycesvinaceus-drappus, 1-1.5 parts of trichoderma spp, 1-1.5 parts of Paecilomyces lilacinus, 1-1.5 parts of bacillus subtilis and 1-1.5 parts of micrococcus. According to the invention, soil pollution control, improvement and nutrition are integrated.

Description

technical field [0001] The invention relates to the field of soil fertilizers, in particular to a bioorganic remediation agent for soil pollution and a preparation method thereof. Background technique [0002] With the development of the economy, environmental pollution is becoming more and more serious, and soil pollution is different from other pollution, mainly manifested as hidden pollution, which has a certain hysteresis and is not intuitive. In particular, heavy metal pollution can generally only be detected through testing, so treatment is difficult and time-consuming. In addition, with the large-scale application of chemical fertilizers and pesticides, the soil shows serious compaction, increased pesticide residues, eutrophication, and reduced agricultability; with the development of large-scale livestock and poultry farming, traditional organic fertilizers for livestock and poultry A series of potential hidden dangers such as antibiotic residues have emerged, which...

[0002] With the development of the economy, environmental pollution is becoming more and more serious, and soil pollution is different from other pollution, mainly manifested as hidden pollution, which has a certain hysteresis and is not intuitive.

Especially heavy metal pollution, generally can only be found through testing, so the treatment is difficult and time-consuming

In addition, with the large-scale application of chemical fertilizers and pesticides, the soil shows serious compaction, increased pesticide residues, eutrophication, and reduced agricultability; with the development of large-scale livestock and poultry farming, traditional organic fertilizers for livestock and poultry A series of potential hidden dangers such as antibiotic residues have emerged, which have seriously affected agricultural production, and at the same time affected the quality and safety of agricultural products and food safety

[0003] Soil remediation is a technical measure to restore polluted soil to normal functions. Currently, commonly used soil remediation methods include physical, chemical and microbial methods. Although physical and chemical methods have direct effects and quick results, their sustainability is poor, and the method or When the dosage is slightly inappropriate, not only the repair effect will not be achieved, but also new pollution will be brought. The composite method is comprehensive, comprehensive, and has strong lasting effect. It will also provide nutrients while repairing, avoiding the barrenness of the soil, and will not cause pollution. will have any adverse effects
