Problems solved by technology

To improve rocky desertified soil, measures such as washing salt, or planting green manure, applying organic manure, or planting rice and other crops can be used to improve its ions; although these methods have certain effects on the improvement of rocky desertified soil, the effect is not Stable, and in practical application, a large amount of manpower, material and financial resources have virtually increased the cost of this measure

Abstract

The invention belongs to the technical field of microbial preparations and relates to a desertification region plant growth improving microbial preparation and a preparation method thereof. The desertification region plant growth improving microbial preparation is composed of, by weight part, 40-60 parts of starch, 10-20 parts of charcoal, 2-5 parts of humic acid, 8-10 parts of microbial agent and15-30 parts of algal polysaccharides, wherein the microbial agent is Brevibacterium Sp. TS22 domesticated at low altitudes and normal temperature with a preservation number of CGMCC 16576; the microbial agent also comprises 0-20% of phosphate solubilizing bacteria by weight. The preparation method of the desertification region plant growth improving microbial agent comprises by weight part mixingthe raw materials of the desertification region plant growth improving microbial agent inside a mixer for reaction to obtain the desertification region plant growth improving microbial agent. The desertification region plant growth improving microbial agent can be applied separately or by being compounded with agricultural and forestry organic fertilizers. The desertification region plant growthimproving microbial agent is simple in operation and low in production cost and improve the emergence rate of desertification region plants by more than 50%.

Description

technical field [0001] The invention belongs to the technical field of plant growth microbial preparations, and in particular relates to a microbial preparation for improving plant growth in rocky desertification areas and a preparation method thereof. Background technique [0002] Rocky desertification, also known as rocky desertification, refers to the phenomenon of loss of surface soil, bare bedrock, loss of agricultural use value of land and degradation of ecological environment due to soil erosion. The thickness of the rocky desertification soil layer is thin (mostly less than 10 cm), and the surface presents an evolution process of gradually exposing rocks similar to desert landscape. In terms of causes, the main factor leading to rocky desertification is human activities. Due to the continuous destruction of natural vegetation over a long period of time, large areas of steep slopes have been reclaimed, resulting in exposed ground, exposed bedrock, and strong scouring...
