Abstract
The invention discloses trichoderma spp for prevention and treatment of watermelon fusarium wilt and an application thereof. Therefore, the trichoderma spp provided by the invention is obtained by isolating and screening soil of watermelon planting fields in Huaiyuan County, Anhui Province and carrying out ray mutagenesis, and is preserved in China Center for Type Culture Collection on May 23, 2019 with the preservation number of CCTCC NO.M2019337. The trichoderma spp strain has obvious prevention and treatment effect on watermelon fusarium wilt, strong disease resistance, bacteriostasis and continuous cropping resistance effects, and obvious characteristics on improving the watermelon yield and taste, not only can improve soil and reduce the use amount of chemical fertilizers and pesticides, but also can reduce the input of farmers and increase the income of the farmers, and plays a positive role in environmental pollution control.
Description
technical field [0001] The invention relates to the technical field of microbial strains, in particular to a Trichoderma for preventing and treating watermelon wilt and an application thereof. Background technique [0002] In recent years, due to the increasingly serious pollution of chemical pesticides, biological control has attracted increasing attention because of its advantages of no pollution, no residue, and safety to the ecological environment and human health. Among them, the application of antagonistic microorganisms in the biological control of plant diseases much attention. Trichoderma is one of the most competitive biocontrol bacteria among many antagonistic microorganisms. It is a type of filamentous fungus that exists widely in nature. It has strong adaptability, many antagonists, wide parasiticity and low environmental impact. With many characteristics, the application potential in plant disease and biological control has been paid more and more attention, a...
