Straw fiber seedling-raising substrate for colonizing biocontrol bacteria, production method of straw fiber seedling-raising substrate, and two-step biocontrol bacteria colonizing method of straw fiber seedling-raising substrate

Abstract

The invention discloses a straw fiber seedling-raising substrate for colonizing biocontrol bacteria, a production method of the straw fiber seedling-raising substrate, and a two-step biocontrol bacteria colonizing method of the straw fiber seedling-raising substrate, and belongs to the technical field of crop colonization biocontrol bacteria. Specifically the two-step biocontrol bacteria colonizing method comprises the following steps: the first step is the colonization of a biocontrol bacteria powder mixed with the substrate, the spray colonization of a biocontrol bacteria water agent, or thespray colonization of a biocontrol bacteria liquid; and the second step is that 10-15 days after the straw fiber substrate colonization biocontrol bacteria, the straw fiber substrate colonized with biocontrol bacteria, and crop seedlings are transplanted into a field simultaneously, and the substrate and crop seedling biocontrol bacteria are colonized in the field, wherein the used biocontrol bacteria are one or a mixture of more than one of Trichoderma aureoviride, Bacillus amyloliquefaciens, Streptomyces parvus, Talaromyces flavus, and Chaetomium aureum. According to the straw fiber seedling-raising substrate for colonizing biocontrol bacteria, the production method of the straw fiber seedling-raising substrate, and the two-step biocontrol bacteria colonizing method of the straw fiber seedling-raising substrate, the biocontrol bacteria can be effectively colonized, thereby the disease resistance of the seedlings is improved, and the stress resistance of seedling transplanting is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of crop colonization biocontrol bacteria, and specifically relates to a straw fiber seedling raising matrix for colonization biocontrol bacteria, a production method thereof and a two-step colonization biocontrol bacteria method. Background technique [0002] Crop disease is one of the main agricultural disasters in my country. It has the characteristics of various types, great impact, and frequent outbreaks. The scope and severity of its occurrence and severity often cause heavy losses to my country's national economy, especially agricultural production. Common crop diseases in my country include the following types of diseases: wheat rust, rice sheath blight, rice blast, wheat head blight, etc., which have become major pests and diseases that seriously affect my country's agricultural production. The crops that people often say, in a broad sense, refer to all plants that have economic value and are cultiva...
