Problems solved by technology

Each strain of the existing Bacillus cereus mainly has a control effect on a kind of disease of plants, and two kinds of diseases individually, and the growth-promoting effect is also that each strain works on individual 1-2 kinds of plants, so it can prevent and treat The type of disease is single, the growth-promoting effect is aimed at a single variety of plants or crops, and the broad-spectrum is poor

Abstract

The present invention discloses a Bacillus cereus strain and microbial bactericide producing process with the strain. The Bacillus cereus strain is named Bacillus cereus 98-I and has good broad-spectrum property, high bacteriostatic activity, plant growth and germination promoting effect and plant resistance inducing effect. The microbial bactericide producing process with the strain includes slant culture of strain, shaking table preparation of strain, the first stage strain preparation and cylinder fermentation with the relevant parameters for every steps being described. The microbial bactericide has wide application in preventing and controlling soil-borne diseases of vegetable, melon, flower and lawn.

Description

technical field [0001] The invention relates to a bacterial strain, specifically a bacterial strain of Bacillus cereus, and also relates to a production method for preparing a microbial bactericide with the bacterial strain. Background technique [0002] Bacillus cereus belongs to the genus Bacillus. At present, there are domestic and foreign literature reports that different strains of Bacillus cereus are used for plant pathogens, disease control and growth promotion. Domestically, such as B.C.sp inhibits rice febrile bacteria, and B.C.S14 controls and promotes cotton diseases. B.C.R2 can prevent and control rice sheath blight, B.C.752 can promote the growth of rice, watermelon and corn, and can detoxify the spores of pathogens. B.C.CS51 can antagonize Narcissus brown spot. growth, B.C has antagonistic effects on wheat take-all and cotton wilt; foreign countries such as Bacillus cereus B.C.uw85, B.C.S18, B.C.W35, B.C.28, B.C.B 0 , B.C.DGA34, B.C.MS1-9, B.C.AS4-12 and othe...
