Tobacco Black Shank Controlling With Antagonistic Microorganisms

Some field demonstration test were adopted in our experiments. bio-control bacteria of microbial fermentation were made into bio-fertilizer application in flue-cured tobacco, and investigate its control effect. The main studies are as follows:1Microbial fertilizer could promote the growth of flue-cured tobacco field. Field observations indicated that after the application of microbial fertilizer in flue-cured tobacco, agronomic characters such as stem height, stem circumference, length and width of the largest leaves were far better than conventional fertilizer.2Microbial fertilizer have significant field control effect on black shank disease Compared with conventional fertilizer, microbial fertilizer, organic fertilizer all can reduce the incidence of field.3Microbial fertilizer can increase tobacco economic benefits. production rate, yield, the average price, the proportion of moderate smoke of the application of different microbial fertilizer were better than the conventional compound fertilizer.
