Problems solved by technology

However, the extensive use of chemically synthesized pesticides has a very bad impact on the environment, so the biological control of rice false smut is particularly important
At present, there is no report that researchers have screened out suitable strains to carry out biological control of rice false smut

Embodiment 1

[0029] A kind of Bacillus velezensis SYQN-1 for controlling rice false smut, the preservation number is: CGMCC No.16566. The preservation date is: October 10, 2018. The depository unit is: General Microbiology Center of China Microbiological Culture Collection Management Committee. Preservation address: Institute of Microbiology, Chinese Academy of Sciences, No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing.

[0030] The screening method of the Veles bacillus for the control of rice false smut comprises the following steps:

[0031] Take soil samples in the paddy fields of the main rice production areas in various places, isolate the microbial strains that exist in the soil from the soil samples, and adopt the three-point confrontation culture method to carry out the confrontation experiment with the rice smut bacteria strain;

[0032] (1) Pour the culture medium suitable for the growth of pathogenic bacteria on the petri dish;

[0033] (2) put a diameter of 5mm ...

Abstract

The invention relates to the technical field of microorganism, and specifically relates to Bacillus velezensis SYQN-1 and application of the Bacillus velezensis SYQN-1 in ustilaginoidea virens. The preservation No. is 16566. The Bacillus velezensis can better prevent and treat ustilaginoidea virens. A result of a three-point confrontation culture method experiment shows that the Bacillus velezensis SYQN-1 can resist the ustilaginoidea virens within an inhibition zone of 31.67 mm.

Description

technical field [0001] The invention relates to the technical field of rice false smut prevention and control, in particular to a kind of Bacillus belesi for the prevention and treatment of rice false smut. Background technique [0002] Rice false smut (Ustilaginoidea virens) is another disease that mainly affects rice production after the three major diseases of rice, rice blast, sheath blight and stripe leaf blight. With the acceleration of the renewal of rice varieties, the improvement of fertilization level, and the change of cultivation system, rice false smut will gradually increase, and in severe cases, it can cause 20% to 30% yield loss, which has a great impact on rice yield. The toxin produced by rice false smut bacteria has serious hidden dangers to the safety of rice eaten by humans and animals and the ecological security of the farmland environment, so rice false smut has been paid more and more attention. The history of rice smut damage is short and the resear...
