Straw fiber seedling raising substrate for colonization and bacteria prevention and its production method and two-step colonization and bacteria control method

Abstract

The invention discloses a straw fiber seedling raising substrate for colonization and bacteria prevention, a production method and a two-step colonization and bacteria control method, and belongs to the technical field of crop colonization and bacteria control. Specifically include: the first step is the colonization of biocontrol bacteria powder mixed with matrix, the spraying and colonization of biocontrol bacteria water, or the spraying and colonization of biocontrol bacteria liquid; the second step is the colonization of straw fiber matrix after 10- 15 days, the straw fiber matrix colonized with biocontrol bacteria and the crop seedlings were transplanted to the field synchronously, and the biocontrol bacteria of the matrix and crop seedlings were colonized in the field; One or more mixtures of Streptomyces, Talaromyces flavus and Chaetomium. The above-mentioned straw fiber seedling-raising substrate for colonization and bacteria prevention, its production method and the two-step colonization and bacteria prevention method can effectively colonize and control bacteria, thereby improving the disease resistance of seedlings, and significantly improving the stress resistance of seedling transplanting.

Description

technical field [0001] The invention belongs to the technical field of crop colonization and bacteria control, in particular to a straw fiber seedling breeding substrate for colonization and bacteria control, a production method thereof, and a two-step colonization and bacteria control method. Background technique [0002] Crop disease is one of the main agricultural disasters in my country. It has the characteristics of many types, great influence, and frequent outbreaks. The scope and severity of its occurrence often cause heavy losses to my country's national economy, especially agricultural production. Common crops in my country include the following types of diseases: wheat rust, rice sheath blight, rice blast, wheat scab, etc., which have become major pests and diseases that seriously affect my country's agricultural production. Crops that people often talk about refer to the plants that have economic value and are cultivated by people in a broad sense. Oil, hemp, sug...
