Traditional Chinese medicine type soil microbial continuous cropping agent and preparation method thereof

Abstract

The invention discloses a traditional Chinese medicine type soil microbial continuous cropping agent which is prepared through two-stage fermentation with beneficial microbes by taking four traditional Chinese medicines as matrixes. The traditional Chinese medicine type soil microbial continuous cropping agent mainly comprises a traditional Chinese medicine type culture medium, bacillus subtilis and trichoderma harzianum which are in a ratio of 40.0:2.0: 1.0, wherein the traditional Chinese medicine type culture medium contains four components with a specified killing or inhibiting effect on harmful germs in soil; the traditional Chinese medicine type culture medium is prepared by the steps of preparing cypress shell, artemisia apiacea, euphorbia helioscopia and dandelion in a ratio of 10:0.3:0.01:0.2; completely drying in the sun; and crushing and sieving with a 1000-mesh sieve. Compared with a chemical agent prevention and control method, the traditional Chinese medicine type soil microbial continuous cropping agent has more thorough germ killing effect; after being applied to soil, the traditional Chinese medicine type soil microbial continuous cropping agent is capable of protecting and synergizing beneficial bacteria in soil while killing pathogenic bacteria and cannot damage a soil structure; since the traditional Chinese medicines are rich in organic matters, the traditional Chinese medicine type soil microbial continuous cropping agent has a soil nourishing and fertilizing comprehensive effect while protecting soil-borne diseases of crops.

Description

technical field [0001] The invention relates to the field of green prevention and control of soil-borne diseases of crops, in particular to a traditional Chinese medicine-type soil microbial cropping agent and a preparation process. Background technique [0002] Food safety is related to the national economy and people's livelihood, and pesticides are one of the main factors affecting the safety of agricultural products. At present, 99% of crop soil-borne diseases are controlled by chemical agents. The frequent use of chemical agents pollutes the environment. With the increase of pathogenic bacteria's drug resistance, the control effect decreases year by year. In actual production, for the frequent occurrence of crop diseases and insect pests, it is difficult to guarantee the yield of crops only by physical methods. With the aging of the main labor force in my country's rural areas, the use rate of farm manure has decreased year by year, and the deterioration of the soil en...

AI Technical Summary

Problems solved by technology

The large and frequent use of various chemical soil fungicides, while killing some beneficial bacteria in the soil, induces the resistance of soil-borne pathogenic bacteria, making it difficult to achieve ideal control effects

The utilization rate of inorganic fertilizers (chemical fertilizers) in my country is only maintained at about 20%. With the accumulation of unusable fertilizers (chemical fertilizers) in the soil, the soil permeability is getting worse year by year, and acidic soil appears, which leads to soil degradation and is unfavorable to crops. to grow

At the same time, the quality of agricultural products has deteriorated

[0003] In agricultural production, producers place more emphasis on the use of chemical fertilizers and neglect the use of organic fertilizers, resulting in a serious shortage of organic matter in the soil, which is not conducive to the activities of microorganisms and primitive animals in the soil

The lack of organic matter in the soil, soil fertility and buffering properties are poor, and it is difficult to fertilize the soil

In recent years, root diseases of crops have shown a trend of increasing year by year. The frequent use of soil fungicides not only prevents the harm of harmful bacteria to crops, but also kills soil due to the non-selective bactericidal effect of fungicides. The beneficial bacteria in the soil destroy the balance of soil colonies, the growth environment of crop roots tends to deteriorate, and the ratio of input to output is out of balance, resulting in low agricultural production efficiency
