Antagonism actinomycetes for preventing and killing continuous cropping cucumber fusarium wilt and microorganism organic fertilizer with antagonism actinomycetes

Abstract

The invention discloses antagonism actinomycetes for preventing and killing continuous cropping cucumber fusarium wilt and a microorganism organic fertilizer with the antagonism actinomycetes, belonging to intensive agriculture production technology. The antagonism actinomycetes CT205, which has an obvious antagonism effect on pathogenic fungus of cucumber fusarium wilt and is obtained by separation, belongs to streptomyces albospinus, and the culture preservation number of the antagonism actinomycetes is CGMCC (China General Microbiological Culture Collection Center) NO.7434. Antagonistic bacteria liquid is fermented and then is subjected to solid fermentation together with organic materials to prepare the microorganism organic fertilizer. Experiments show that after the microorganism organic fertilizer is applied into soil, the antagonistic bacteria can breed rapidly and form a dominant bacterial community in the soil, and the preventive rate of the antagonism actinomucetes in soil with serious cucumber fusarium wilt can reach more than 80%.

Description

technical field [0001] The invention relates to an antagonistic actinomycete for preventing and eliminating continuous-cropping cucumber wilt and microbial organic fertilizer thereof, which belongs to the technical field of agricultural intensive production and is specially used for overcoming and eliminating the problem of continuous-cropping cucumber wilt. Background technique [0002] Cucumber is an important economic crop in my country. Cucumber wilt is one of the main diseases of cucumber, which occurs all over the country, especially in protected planting. Cucumber wilt is a soil-borne disease caused by Fusarium oxysporum. It is widely distributed in tropical, subtropical and some warm regions all over the world. It was first discovered and reported in the Netherlands in 1943. At present, in my country's highly intensive cucumber planting areas, when Fusarium wilt occurs, the yield loss is more than 80%. Spread and have a strong ability to adapt to the environment. Fu...

Problems solved by technology

[0003] On the other hand, the incineration of rice, wheat, corn, rapeseed and other crop straws, and the disposal of livestock and poultry manure after large-scale breeding not only seriously pollute the environment, but also greatly waste the organic fertilizer and bio-organic fertilizer products. Raw materials; a large number of nutrient resources (C, N, P, K, S and trace elements) are lost outside the soil-plant system, which obviously weakens the ability of my country's sustainable agricultural development
