Microbe, application of microbe in bio-fertilizer preparation, bio-fertilizer and application of bio-fertilizer

The invention provides a microbe, an application of the microbe in bio-fertilizer preparation, a bio-fertilizer and an application of the bio-fertilizer. Compared with the existing microbe for the bio-fertilizer and the existing bio-fertilizer in the prior art, the microbe provided by the invention refers to trichoderma viride, can produce abundant hypha, efficiently express the high-activity special enzyme system such as beta-1,4-glucosan hydrolase, chitinase, cellulase, protease to generate volatile or non-volatile active substances capable of inhibiting pathogenic bacteria growth, so that the microbe can be used for preparation of the bio-fertilizer. When the bio-fertilizer is used for promoting crop growth, the bio-fertilizer can preferably improve the soil physicochemical property, so as to improve the crop yield and facilitate sustained development of the agricultural production fundamentally.
