Embodiment 1

[0025] A microbial preparation for promoting the growth of plant roots, comprising the following raw material components and parts by weight, 70 parts of starch, 10 parts of microbial inoculum, 20 parts of seaweed polysaccharide, and the microbial inoculum also includes domesticated culture, mixed in equal proportions of soil hair Agrobacterium rhizogenes and Bacillus megaterium, the total weight is 10% of the microbial agent;

[0026]The microbial agent is obtained from Brevibacterium sp.TS22 from the Qinghai-Tibet Plateau through low-altitude and normal-temperature domestication. It is preserved in the General Microbiology Center of China Microbiological Culture Collection Management Committee. The preservation number is: CGMCC16576; low-altitude and normal temperature domestication The method is: inoculate Brevibacteria isolated from the soil of the Qinghai-Tibet Plateau into LB medium, and subculture repeatedly at room temperature to obtain Brevibacterium adapted to low alt...

Abstract

The invention belongs to the technical field of microbial preparations, and relates to a microbial preparation for promoting plant root system growth and a preparation method thereof. The microbial preparation comprises 60-70 parts of starch, 8-10 parts of a special microbial agent, and 20-32 parts of algal polysaccharide, wherein the microbial agent is low-altitude and normal-temperature domesticated Brevibacterium sp. TS22, and a preservation number is CGMCC 16576; and the microbial agent further comprises a mixed bactericide of a phosphate solubilizing bacterial strain and a soil rooting agrobacterium, and a weight is 0-20% of the microbial agent. The preparation method for the microbial preparation comprises the following steps: putting raw material components of the microbial preparation in parts by weight into a stirrer, stirring and reacting, to obtain the microbial preparation for promoting the plant root system growth. The microbial preparation is independently used or compounded with an agriculture and forestry organic fertilizer for using. The microbial preparation is simple and convenient in operation, low in production cost, and capable of remarkably improving the rootsystem growth of a plant.

Description

technical field [0001] The invention belongs to the technical field of microbial preparations, and in particular relates to a microbial preparation for promoting plant root growth and a preparation method thereof. Background technique [0002] The root system is the general term for all the roots of a plant. The functions of the plant root system mainly include: (1) Fixation and support: In nature, the root system first stabilizes the plant in the soil and supports the aboveground to reduce external influences; (2) ) Storage function: During the growth of crops, nutrients will be continuously moved to the roots. If the aboveground part produces insufficient nutrients, it will take nutrients from the roots to maintain its normal growth; The absorption of nutrients and nutrients is the most familiar to us, and it is also one of the most important functions of the root system; (4) Conduction function: This part of the function is a continuation of the previous part, and the who...
