The disclosure belongs to the technical field of microbes, and in particular relates to a bacillus subtilis with disease resistance and improved fruit quality and an application thereof. The use of microbial agents to increase crop yields and prevent pests and diseases can effectively reduce the harmful effects of traditional chemical agents on soil. The disclosure provides a Bacillus subtilis (B.subtilis) 21c and its compound preparation. The strain has antagonism to plant fungal pathogens and plant bacterial pathogens, and especially has a remarkable control effect on plant root rot; at the same time, the compound preparation is used in The tomato experiment in the greenhouse can increase the fruit yield by 15%; effectively prevent and control the diseases that occur during the tomato growth process, and the control effect is as high as 80%; all the indicators of the tomato fruit have been improved, and the lycopene content has been significantly increased. While improving the quality of crops, it can reduce the harmful effect on soil, which has good popularization significance. |
