Biological intelligence fungus block formula for preventing and treating nematodes and preparation method of biological intelligence fungus block

Abstract

The invention relates to a biological intelligence fungus block for preventing and treating stubby root nematodes. The biological intelligence fungus block is prepared by fermenting and drying three bacterial strains: ACCC11084: bacillus megaterium bacillus megaterium de Bary, ACCC10632: bacillus subtilis (Ehrnberg) Cohn and ACCC32001: paecilomyces lilacinus (Thom.)Samson to obtain bacterial strain mother powder, and then mixing and pressing with carrier auxiliary materials at the ratio. The intelligence fungus block can be used for growing seedlings of multiple vegetables, flowers and economic crops, is capable of preventing nematodes from damaging plants during the seedling stage, still can play good prevention and treatment roles on the stubby root nematodes after being transplanted into a field or a greenhouse, and especially has a good control effect on soybean cyst nematodes, cucumber root knot nematodes and peanut root knot nematodes.

Description

technical field [0001] The invention relates to a seedling-raising bacterial block, in particular to a formula and a preparation method of a living biological intelligent bacterial block which can be used for preventing and treating plant root nematode diseases. Background technique [0002] Root nematodes are a kind of resident endoparasitic nematodes, which infect the roots of plants and produce root knots, which are characterized by wide distribution and great harm. On the one hand, they produce some chemical substances to stimulate the plant host to form giant cells, forming a large number of root knots in the root system, affecting The root system absorbs water and nutrients; on the other hand, because of its infection, it causes a large number of wounds, which is conducive to the secondary infection of soil pathogens. This compound infection aggravates the loss of crop yield and the decline of quality. [0003] At present, the prevention and control of root nematodes i...

[0002] Root nematodes are a kind of resident endoparasitic nematodes, which infect the roots of plants and produce root knots, which are characterized by wide distribution and great harm. On the one hand, they produce some chemical substances to stimulate the plant host to form giant cells, forming a large number of root knots in the root system, affecting The root system absorbs water and nutrients; on the other hand, it causes a large number of wounds due to its infection, which is conducive to the secondary infection of soil pathogens, and this compound infection aggravates the loss of crop yield and the decline of quality

[0003] At present, the prevention and control of root nematodes is mainly the method of using chemical nematicides, but as people pay more and more attention to environmental issues and pollution-free food production today, many highly toxic substances that seriously pollute the environment and are harmful to human and animal health , high-residual and triple-toxic chemical nematicides have been gradually banned
