Embodiment 1

[0029] A strain of Bacillus altitudinis DSQ N-1, the preservation number of which is: CGMCC No. 17236. The preservation date is: January 25, 2019. The depository unit is: General Microbiology Center of China Committee for the Collection of Microbial Cultures. The preservation address is: Institute of Microbiology, Chinese Academy of Sciences, No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing.

[0030] The screening method of the highland bacillus bacterial strain comprises the following steps:

[0031] Soil samples were taken from paddy fields in the main rice producing areas of various places, and the microbial strains existing in the soil were isolated from the soil samples, and the three-point confrontation culture method was used to conduct confrontation experiments with rice sheath blight strains;

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

[0033] (2) put a rice sheath blight fungus bacterium cake ...

Abstract

The invention relates to the technical field of control of rhizoctonia solani, in particular to a bacillus altitudinis strain (bacillus altitudinis) DSQN-1 of which the preservation number is CGMCC No.17236, and the strain as a biological control bacterium is used for performing biological control on the rhizoctonia solani. The bacillus altitudinis strain disclosed by the invention has better control effects on the rhizoctonia solani; and experiment is performed by a three-point face-to-face-culturing method, and the result indicates that the inhibition zone of the bacillus altitudinis (bacillus altitudinis) DSQN-1 on the rhizoctonia solani is 27.33mm.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of rice sheath blight, in particular to a strain of bacillus uplander and its application on rice sheath blight. Background technique [0002] Rice sheath blight (Rhizoctonia solani) is a worldwide rice disease and one of the three major diseases in rice production in my country. The disease mainly affects leaf sheaths, leaves, stems and ears of rice, and large areas of moiré-like lesions are produced at the diseased site, which affects photosynthesis and nutrient delivery, resulting in an increase in grain rate and a decrease in thousand-grain weight. In severe cases, the whole plant dies. Generally, it causes a loss of 5% to 10% of output, and a serious reduction of 30% to 50% of output. Long-term use of chemical agents will cause environmental pollution, damage to ecological balance, and pesticide residues, while biological control is safe for the environment, safe for non-tar...
