Problems solved by technology

As we all know, chlamydospores have strong stress resistance, long shelf life and high control effect, but because it is very difficult to induce Trichoderma chlamydospores to form a large number of chlamydospores, and the fermentation technology of Trichoderma chlamydospores is relatively difficult, so commercialization at home and abroad Trichoderma chlamydospore preparations rarely

Abstract

The invention discloses a wettable powder composition based on trichoderma harzianum M-17 chlamydospore as well as a preparation method and application of the wettable powder composition. The wettable powder composition comprises chlamydospore powder, a carrier, a wetting agent, a dispersing agent and an ultraviolet protective agent, and the chlamydospore powder is obtained by performing amplification culture on trichoderma harzianum M-17 strains; the fungus type of the Trichoderma harzianum M-17 strain is Trichoderma harzianum, the preservation number of the Trichoderma harzianum M-17 is CCTCC NO: 2018538, the Trichoderma harzianum M-17 is provided by the Institute of Plant Protection, Academy of Agriculture and forestry Sciences in Ningxia, the M-17 contained in the wettable powder composition has an inhibition effect on pathogenic bacteria of soil-borne diseases of potatoes, reduces harmful fungi in soil and can promote the development of root systems, the soil nutrition absorption capability is enhanced, the stress resistance of the potatoes is improved, the growth promoting effect is achieved, the overground biomass accumulation is increased, and the yield is obviously increased.

Description

technical field [0001] The invention relates to the technical field of trichoderma preparations for agriculture. Specifically, it relates to a wettable powder composition, preparation method and application based on Trichoderma harzianum M-17 chlamydospore. Background technique [0002] Chemical fertilizers and pesticides are irreplaceable inputs to ensure national food security and the effective supply of major agricultural products. In 2015, the total amount of chemical fertilizers and pesticides in my country exceeded 60 million tons, and the total amount of pesticides exceeded 1.8 million tons. The total amount of chemical fertilizers and pesticides is 33%. Therefore, with the continuous development of agriculture, it has become a problem to solve the ecological environment pollution caused by the excessive application of pesticides, the decline of cultivated land quality, the destruction of biodiversity, the quality and safety of agricultural products, and the continuous...
