Inocula for preventing apple fungous diseases and increasing yield, and special strain therefore and use thereof

The invention discloses a microbial inoculum for controlling apple fungus diseases. The active ingredients of the microbial inoculum comprise bacillus subtilis and bacillus pumilus. The microbial inoculum for controlling apple fungus diseases mainly can control ring rot of apple with the control efficiency being over 80%, and also can treat other fungus diseases; the control efficiency for apple powdery mildew is within the range of 30-60%, the control efficiency for red rot can reach 45%, the control efficiency for tan rot can reach 40%, and the control efficiency for alternaria leaf spot in apple can reach 42.33%; therefore, the average yield per mu of the apples is increased by 9.3%, the quality of the apples is obviously improved, and the resistance of the apples is remarkably enhanced.
