Microbial fertilizer as well as preparation method and application thereof

Abstract

The invention relates to microbial fertilizer as well as a preparation method and application thereof, and belongs to the field of comprehensive control of plant soil-borne diseases. The microbial fertilizer comprises a microbial agent, a nutritional agent, a carrier and water; the microbial agent comprises bacillus laterosporus, streptomyces jingyangensis, streptomyces lavendulae, streptomyces aureofaciens, bacillus mucilaginosus and trichoderma viride. The microbial fertilizer provided by the invention contains functional microorganisms capable of inhibiting and killing pathogenic bacteria in soil, can effectively prevent and treat tomato canker by a method for inhibiting bacteria by bacteria and can improve the soil healthy environment; germs can be killed from the soil root, various ways of seeds, seedlings, irrigating water, farm tools and the like can be blocked, and pathogen transmission can be avoided; the microbial fertilizer adopts natural microorganisms in the natural world,is green and free of pollution and has long-term effect; the use of pesticide is reduced, the planting cost is reduced and environmental pollution is reduced.

Description

Technical field [0001] The invention relates to a microbial fertilizer and a preparation method and application thereof, belonging to the field of comprehensive prevention and control of plant soil-borne diseases. Background technique [0002] Tomato canker is one of the most serious diseases in tomato production. Since it was first reported in the United States, it has rapidly spread and spread to many major tomato producing areas in the world, and has gradually become a worldwide disease. At present, the disease is widespread in North America, Europe, Asia, Africa, Oceania, and covers more than 60 countries including the United States, Britain, Canada, Germany, and Japan. my country first discovered tomato canker in Pinggu, Beijing in 1985, and it has now spread to many tomato producing areas. The occurrence of tomato canker in Northeast my country was confirmed in 1993 for the first time. In 2002, the incidence of tomato in Fangtang Township, Guoning City, Anhui Province exce...

Problems solved by technology

[0004] At present, the prevention of tomato canker is mainly based on prevention. Doing a good job of prevention in the early stage of the disease will have a better effect on the control of the disease. The methods adopted mainly include measures such as strengthening quarantine, seed treatment, soil treatment, crop rotation, and chemical control. However, these methods have many disadvantages such as incomplete treatment, polluting the environment, affecting crop growth, etc., and they only treat the symptoms but not the root cause, and do not kill the pathogenic bacteria from the root cause. will happen again
