The invention provides bacillus subtilis and preparation and application of a microbial inoculum thereof. The invention mainly relates to a Bacillus subtilis Y-1 of which the preservation number is CGMCC No.6539, and also relates to the microbial inoculum which is prepared from the bacillus subtilis, and application of the microbial inoculum. The Y-1 strain can be colonized on an apple tree, a polar tree, a cucumber and the rhizosphere of capsicums and in an apple tree, and has efficient and broad-spectrum antibacterial activity on fusarium, rhizoctonia solani, pestallozzia theae, phytophthora and the like; the microbial inoculum of the bacillus subtilis can be used for controlling diseases and continuous cropping obstacles of an apple tree, a polar tree, a cucumber and capsicums caused by those disease fungi. The preparation method of the microbial inoculum is simple in process, short in fermentation cycle, low in cost, and favorable for industrial production. |
