Abstract

The invention provides a strain of Alcaligenes faecalis Y1 and its application in preventing and controlling soil-borne diseases of crops. The preservation number of the said Alcaligenes faecalis Y1 is CGMCC NO.13510, and it is made into a microbial agent that has obvious effects on promoting the growth and production of sunflowers in the field, and its effect is not inhibited by field soil conditions and the use of chemical fertilizers, and can be used in light In high salinity farmland, it is applied together with chemical fertilizers. The fungal agent has a control effect of more than 95% on the rotten disc disease caused by sunflower sclerotin, and a 100% control effect on rust. The microbial agent is of great significance to the prevention and control of soil-borne diseases and continuous cropping obstacles in my country's farmland, the continuous increase of grain production and the protection of the ecological environment of farmland.

Description

technical field

[0001] The invention relates to the technical fields of microbiology and plant disease biocontrol, in particular to a strain of Alcaligenes faecalis Y1 and its application in preventing and controlling crop soil-borne diseases. Background technique

[0002] With the improvement of crop yield and the development of facility agriculture, the problems of soil-borne diseases and continuous cropping obstacles have become increasingly prominent, and soil pathogenic microorganisms have continued to increase, causing crop yield reduction or even failure. Soil-borne diseases and continuous cropping obstacles have become bottlenecks in the development of safe agricultural production. Continuous cropping for 3 years will reduce yield by 10% to 20%, and crop yield will decrease by 40% to 50% in continuous cropping for 4 to 5 years. Soil-borne diseases of protected vegetables, potatoes, garlic, sunflower, rapeseed, cotton, soybean, rice, wheat, and sugar beet occur frequ...
