preparation example Construction

[0020] The preparation method of the biological seedling-growing substrate with the function of preventing and treating clubroot according to the present invention includes the steps of nutrient substrate assembly, addition of functional strain fermentation liquid, mixing and screening, specifically comprising

[0021] 1) First select 3 to 5 parts of humus, 1 to 3 parts of perlite, and 0.5 to 2 parts of vermiculite, crush, sieve, and mix evenly to obtain the bottom matrix, and then add a total weight ratio of 3-7% organic fertilizer and 2-4% compound fertilizer, mixed evenly to obtain the nutrient matrix;

[0022] 2) Add the fermented liquid of functional strains to the nutrient matrix and mix evenly. The proportion of the fermented liquid of functional strains is 1‰~5‰ of the total weight of the substrate; the effective number of viable bacteria in the fermented liquid of functional strains is greater than 2.0× 10 10 cfu / mL.

[0023] 3) Mix and sieve, mix the nutrient matri...

Abstract

The invention discloses a biological seedling-raising substrate with the function of preventing and treating clubroot, comprising a bottom substrate and a fermentation broth of functional strains. A method for preparing a biological seedling raising substrate with the function of preventing and treating clubroot comprises the steps of composing a nutrient substrate, adding a fermentation liquid of functional strains, and mixing and sieving. An application method of a biological seedling substrate with the function of preventing and treating clubroot, comprising the steps of preliminary preparation, plate loading and sowing. The biological seedling substrate of the invention integrates moisture retention, ventilation and loosening, which is conducive to the early growth and rapid growth of seedlings, promotes the tidy and consistent growth of seedlings in the early stage, and can overcome the infection of soil-borne diseases in the early stage of seedlings, especially clubroot; in the subsequent growth process It can also effectively prevent and control the occurrence of diseases. It can effectively reduce the amount of pesticides without residues, reduce environmental pollution, improve the quality of seedlings, achieve harmless prevention and control of diseases at the seedling stage, protect the ecological environment, and facilitate popularization and application.

Description

technical field [0001] The invention relates to the technical field of microbial strains and applied agriculture, in particular to a biological seedling-growing substrate with the function of preventing and curing clubroot and a preparation method thereof. Background technique [0002] Species-borne and soil-borne diseases of crops are important limiting factors affecting seedling emergence rate, seedling quality and yield. With the development of high-efficiency agriculture such as agricultural intensification, substrate seedling cultivation has become the most important measure. However, due to poor management in the seedling raising process, the seedlings are diseased and the substrate seedling raising has become the source of disease transmission. In addition, many diseases cannot be controlled once they are infected at the seedling stage. Therefore, how to control the disease at the seedbed stage has become an important management link in substrate seedling cultivatio...
