Abstract

The invention discloses a trichoderma fungus culture medium. The culture medium is prepared from the following components in parts by mass: 15-25 parts of kitchen waste material dry powder, 20 parts of agar and 1,000 parts of water. The trichoderma fungus culture medium can completely replace PDA culture to provide sufficient nutrients for the growth of trichoderma fungus, and can effectively solve current problems.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a Trichoderma fungus culture medium and a preparation method thereof. Background technique [0002] Trichoderma belongs to the fungal phylum, Deuteromycotina, Hyphospora, Hyphospora, Polyporaceae, and Trichoderma, which widely exist in soil under different environmental conditions. Most Trichoderma can produce a variety of biologically active substances that have antagonistic effects on plant pathogenic fungi, bacteria and insects, such as cell wall degrading enzymes and secondary metabolites, and can improve the stress resistance of crops, promote plant growth and improve agricultural products. Therefore, it is widely used in biological control, biological fertilizer and soil conditioner, and has strong commercial value. [0003] At present, PDA (potato dextrose agar medium) or improved PDA medium is mostly used for the isolation and culture of Trichoderma fungus. In commercial app...
