Method for fermenting soil

Abstract

The invention discloses a method for fermenting soil. The method specifically comprises the steps of mixing beneficial bacterium and an active substance in ratio of 1: 3-1: 9 to obtain a mixture; uniformly paving the mixture into the soil or applying into the soil along a furrow, wherein the mixture is 10 to 40cm in the soil; watering the soil until the humidity of the soil is 30 to 80%; fermenting for 3 to 5 days; maintaining the humidity to be 30 to 80% to continuously ferment for 10 to 30 days after white mycelium appears in the soil. According to the method, beneficial bacterium is added, so that harmful substances in the soil can be degraded, the compounding state of heavy metal is changed, and the nutrition in the soil is released; paecilomyces lilacinus can inhibit nematode; various bacteria interact and promote the growth, and thus dominant bacteria can be quickly obtained; with the adoption of the method, pesticide residue can be reduced, and the heavy metal can be passivated; the beneficial bacterium is added, and nematode can be inhibited; hardening is removed; the concentration of pesticide residue in the soil can be reduced to be 10mg / kg; the content of heavy metal in the soil is less than 30mg / kg; the nematode inhibition rate is 50 to 90%; the aggregate structure improvement rate of the soil is 40%.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a soil fermentation method. Background technique [0002] my country's soil is facing a huge problem. The quality of the soil directly affects the next industrial chain and the health of the people. People eat plants, and most of the nutrients of plants are drawn from the soil. The ecological environment of the soil directly affects plants and people. The area of ​​cultivated land in our country is decreasing year by year, but pollution has always existed and is expanding year by year. The current soil treatment method is simple. By using chemical products, the symptoms are cured, not the root cause. The soil improvement effect of a single strain of bacteria is not ideal, and the large-scale use of chemical pesticides leads to pesticide residues. Unreasonable use of fertilizers leads to the accumulation of heavy metals and the disappearance of beneficial bacteria...

AI Technical Summary

Problems solved by technology

[0005] The technology of fermenting soil has not been reported in China. Most of them are fermenting straw and fermenting agricultural waste. These technologies have a certain effect on soil problems, mainly to improve soil organic matter. There are few reports on the method of directly fermenting soil

Most of the existing technologies are chemical methods, commonly used for soil disinfection, destroying beneficial bacteria in the soil, resulting in soil compaction, which must be repeated every year. Biological methods mostly use a single bacterium, which is easily affected by the soil environment, and the added bacteria are easily homogenized ; unsatisfactory

That is, the existing technologies are all aimed at solving a single problem, and it is difficult to solve the antagonism and symbiosis between bacteria and bacteria.
