Trichoderma harzianum strain and application thereof

Abstract

The invention discloses a trichoderma harzianum strain and application thereof. The trichoderma strain is a trichoderma harzianum strain Hb13-3-2 CGMCC No. 13163. The strain and metabolites thereof have broad-spectrum activities of inhibiting pathogenic fungi. The contrast growth experiment proves that the trichoderma harzianum strain has the capacity of resisting red root pathogenic bacteria of rubber trees, colletotrichum gloeosporioides and other pathogenic bacteria, and further has the effects of controlling multiple other pollution microbes and promoting growth of rubber seedlings. Therefore, the trichoderma harzianum strain can be immediately applied to the cultivation process of the rubber trees at the seedling stage, healthy growth of the rubber seedlings is promoted, and occurrence of rubber tree root diseases can be shielded or inhibited.

Description

technical field

[0001] The invention relates to a strain of multifunctional Trichoderma harzianum strain and application thereof. Background technique

[0002] Trichoderma Trichoderma Pers. (the sexual stage was once called "Hypocrea Fr.") belongs to Sordariomycetes, Ascomycota, Hypocreaceae, and Hypocreales. This genus of fungi has a wide variety of species and is widely distributed. It is an important class of renewable natural resources with high economic value and application prospects (Doi 1969, 1972; Zhu Zhaoxiang and Zhuang Wenying, 2014). Trichoderma spp. is an important class of multifunctional probiotic fungi that widely exist in nature. They can not only control the infection of pathogenic bacteria and the occurrence of diseases through a variety of mechanisms, but also have the ability to promote crop growth and improve crop resistance to biotic and abiotic stress. They are recognized as environmentally friendly fungi and are used in agriculture, In the fields ...
