Microbial organic fertilizer for preventing and treating fusarium wilt of cotton and preparation method of microbial organic fertilizer

Abstract

The invention discloses a microbial organic fertilizer for preventing and treating fusarium wilt of cotton. The microbial organic fertilizer comprises the following raw materials in parts by weight: 80-120 parts of fresh chicken manure; 4-6 parts of a mixture of peach leaf powder, radix stemonae powder and camphor powder; 14 to 16 parts of egg shell powder; 9-11 parts of modified medical stone powder; 12 to 14 parts of konjaku flour; 24-26 parts of a compound microbial agent fermentation broth; 12 to 13 parts of guanidine gum; 12 to 13 parts of sodium alginate; 12-13 parts of boric acid and 15-17 parts of calcium superphosphate; the microbial organic fertilizer disclosed by the invention can be used for effectively preventing and treating fusarium wilt in the growth period of cotton and has a long-acting effect of preventing and treating the fusarium wilt of the cotton; meanwhile, the fertilizer also contains nutritional ingredients for promoting the growth of the cotton, has an effect of promoting the growth of the cotton, and can remarkably improve the yield of the cotton.

Description

technical field [0001] The invention belongs to the field of microbial organic fertilizer, and in particular relates to a microbial organic fertilizer for preventing and treating cotton wilt and a preparation method thereof. Background technique [0002] Cotton wilt is a disease caused by Fusarium oxysporum. It is a typical vascular disease. There is a risk of infection throughout the growth and development of cotton. It can cause dead seedlings in the early stage, and cause cotton leaves and buds to fall off in the later stage. , or even die, the occurrence of Fusarium wilt significantly affects the growth of cotton, resulting in a reduction in cotton yield; [0003] At present, the commonly used methods for the prevention and control of cotton fusarium wilt are mainly chemical agents. For the occurrence of Fusarium wilt in different periods, chemical agents need to be applied frequently. It can only temporarily solve the temporary disease, but cannot achieve long-term eff...

[0002] Cotton wilt is a disease caused by Fusarium oxysporum. It is a typical vascular disease. There is a risk of infection throughout the growth and development of cotton. It can cause dead seedlings in the early stage, and cause cotton leaves and buds to fall off in the later stage. , or even die, the occurrence of Fusarium wilt significantly affects the growth of cotton, resulting in a decrease in cotton yield;

[0003] At present, the commonly used methods for the prevention and control of cotton fusarium wilt are mainly chemical agents. For the occurrence of Fusarium wilt in different periods, chemical agents need to be applied frequently. It can only temporarily solve the temporary disease, but cannot achieve long-term effective control effect;

[0004] Biological control utilizes the relationship between biological species to achieve the effect of disease prevention and control by one or one type of organisms inhibiting another or another type of organisms. It has the characteristics of environmental friendliness, but the simple biological control microbial bacteria The control effect of pesticides on plant diseases and insect pests is limited, and the growth-promoting effect on plants is limited, and they are often used in conjunction with organic fertilizers; and there is also the problem of poor storage stability, so it is urgent to research and develop a microbial organic fertilizer with long-term control of cotton wilt. Fertilizer; it can not only prevent and control diseases, but also has the effect of promoting crop growth and increasing yield
