Disease-resistant microbial composite inoculant for preventing and treating fungus soil-borne disease of cigarettes and tobaccos, biological organic fertilizer and preparation method thereof

Abstract

The invention relates to a disease-resistant microbial composite inoculant for preventing and treating a fungus soil-borne disease of cigarettes and tobaccos, a biological organic fertilizer and a preparation method thereof, and belongs to the technical field of production of agricultural fertilizers. The disease-resistant microbial inoculant comprises bacillus subtilis, bacillus amyloliquefaciens, streptomyces microflavus and trichoderma viride, and the total viable count of the disease-resistant microbial inoculant is 5*108 cfu / g. The biological organic fertilizer is mainly prepared from thedisease-resistant microbial composite inoculant and the following raw materials in parts by weight: 5-10 parts of a microbial fermentation inoculant, 70-75 parts of oil cake and 15-20 parts of straws. The biological organic fertilizer is pollution-free to the environment, and has a good effect of preventing and treating the fungus soil-borne disease of the cigarettes and tobaccos.

Description

technical field [0001] The invention relates to a disease-resistant microbial compound bacterial agent for preventing and treating tobacco fungal soil-borne diseases, a bio-organic fertilizer and a preparation method thereof, belonging to the technical field of agricultural fertilizer production. Background technique [0002] Soil-borne disease is a disease in which pathogenic bacteria survive in the soil or on the soil surface and invade the soil and above-ground plant stems. Its occurrence is closely related to various factors such as the transmission characteristics of the pathogen, climatic conditions, continuous cropping cultivation, and the resistance of the variety. relevant. Tobacco fungal soil-borne diseases use the complex soil environment as the culture medium and are based on the interdependence among the three factors of host, parasite and soil microorganisms, while other plant diseases generally only rely on the interaction between host and parasite. Therefore...

AI Technical Summary

Problems solved by technology

Tobacco fungal soil-borne diseases use the complex soil environment as the culture medium and are based on the interdependence among the three factors of host, parasite and soil microorganisms, while other plant diseases generally only rely on the interaction between host and parasite. Therefore, the control of tobacco fungal soil-borne diseases is more difficult

Pathogens usually infect the roots of tobacco from the soil, causing diseases on the roots of crops and even the whole plant, resulting in significant economic losses

At present, chemical control is the main method for the prevention and control of tobacco fungal soil-borne diseases, but chemical control has great side effects on the environment, and drug residues are harmful to human health. The effect decreases or even the prevention and control fails

Crop rotation is one of the effective methods to control soil-borne diseases of tobacco fungi, but due to the large population and limited land in my country, normal crop rotation measures in production cannot be realized
