Preparation of protected degenerated soil repairing agent

Abstract

The invention relates to a method for preparing installation degraded soil remediation agent, which belongs to the field of bacterial manure preparation. The method uses matured chicken manure, zeolite powder and pulverized lignite which are widely available and low in cost as a carrier, sprays bacillus megaterium, bacillus subtilis and silicate bacteria which have already been widely used and play a role in phosphate-solubilization and potassium-solubilization and azotobacteria which plays a role in nitrogen fixation onto the carrier, and produces the degraded soil remediation agent by a method of pan granulation and low-temperature drying. The method adopts a simple process, produces products with high performance and quality at low cost, solves the serious soil degradation problem caused by use of a large amount of disinfectant and improves the utilization rate of fertilizer, thereby improving crop output during agricultural facility production.

Description

technical field [0001] The invention belongs to a method for preparing bacterial manure, and in particular prepares a degraded soil restoration agent for the problem of soil degradation caused by long-term and large-scale application of fungicides in facility agricultural production. Background technique [0002] China uses about 800,000 to 1,000,000 tons of chemical pesticides every year to prevent and control various diseases, insect pests and weeds, of which the annual usage of fungicides is about 91,000 tons. According to data, only about 10% to 15% of pesticides are actually applied to harmful organisms when the aboveground parts of plants are sprayed, and the remaining pesticides remain in plant tissues, water bodies and soils. It can be seen that the use of fungicides will cause poisoning to beneficial microorganisms in the soil environment while killing harmful pathogenic bacteria and viruses. The use of fungicides in facility agricultural production is large and fr...

Problems solved by technology

However, due to the wide variety of fungicide applications, and the currently screened fungicide-degrading bacteria are all biological strains that specifically degrade a certain fungicide, the use of fungicide biodegrading bacteria to restore degraded soil in facility agricultural production can only The pollution caused by a certain fungicide does not have a broad spectrum, and the use of degrading bacteria often leads to the rapid degradation of the fungicide and reduces the control effect on diseases
