Microbial growth promoter specially used for ecological planting of wild rice stems and preparation method thereof

Abstract

The invention provides a preparation method of a microbial growth promoter specially used for ecological planting of wild rice stems. The preparation method comprises the following steps: 1) preliminarily screening pseudomonas, azotobacter chroococcum, bacillus subtilis, methylomonas and streptomycete respectively from wild rice stem planting soil and respectively obtaining strains with high growth rates through further screening; 2) carrying out mixed culture on the strains obtained in the step 1) in a liquid culture medium to obtain mixed bacterium liquid; 3) carrying out solid enlarge culture on the mixed bacterium liquid in a solid enlarge culture medium to obtain an initial fermented product; and 4) drying the initial fermented product, adding matrix carriers and carrying out sieving and subpackaging, thus obtaining the microbial growth promoter. The inventors of the application improve existing wild rice stem planting methods and design the planting methods and fertilizer use according to the law of requirements of wild rice stems for fertilizers in the growth process, thus obtaining higher yield and high-quality fruit and increasing the economic benefits of planting.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a microbial growth promoter, in particular to a microbial growth promoter specially used for the ecological planting of wild rice stems and a preparation method thereof. Background technique [0002] Zizania is a vegetatively propagated aquatic perennial gramineous crop, commonly known as: Zizania bamboo shoot, Zizania melon, its fleshy stem contains 4% sugar, 1.5% protein, and is rich in multivitamins, so it is deeply loved by consumers. Zizania is native to China and Southeast Asia. It is a relatively common aquatic vegetable. It is a spindle-shaped fat part formed by the tender stems of the Gramineae plant, which is stimulated by the fungus Ustilago smut. At present, only China and Vietnam cultivate Zizania as a vegetable, and China is the earliest. Wild rice stems are distributed throughout the north and south of my country, and are planted in Hebei, Jiangsu, Zhejiang, Anhui, J...

AI Technical Summary

Problems solved by technology

However, in the traditional planting method of Zizania, the problems of soil agglomeration and compaction are extremely serious due to the extensive use of chemical fertilizers, which in turn leads to the deterioration of soil quality, low yield of Zizania, and poor economic benefits.
