Embodiment 1

[0026] An ecological preparation for promoting the growth of plants in sandy land, comprising the following raw material components and parts by weight: 68 parts of starch, 10 parts of humic acid, 2 parts of superphosphate, 10 parts of microbial agent, 20 parts of seaweed polysaccharide, microbial bacteria The agent also includes Bacillus megaterium after domestication and cultivation, and the weight is 10% of the microbial agent;

[0027] 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 lo...

Embodiment 2

[0033] An ecological preparation for promoting the growth of plants in sandy land, comprising the following raw material components and parts by weight: 60 parts of starch, 10 parts of humic acid, 2 parts of superphosphate, 8 parts of microbial agent, 20 parts of seaweed polysaccharide, microbial bacteria The agent also includes Agrobacterium, and the weight is 20% of the microbial agent. ; The microbial agent is derived from Brevibacterium sp. TS22 from the Qinghai-Tibet Plateau through low-altitude and normal temperature domestication, and is preserved in the General Microbiology Center of the China Committee for the Collection of Microbial Cultures. The preservation number is: CGMCC 16576; low Altitude and normal temperature acclimation methods are as follows: Brevibacteria isolated from the soil of the Qinghai-Tibet Plateau are inoculated into LB medium, and subcultured repeatedly at room temperature to obtain Brevibacterium adapted to low altitude and normal temperature co...

Abstract

The invention belongs to the technical field of ecological preparations, and relates to an ecological preparation for promoting sandy land plant growth and a preparation method thereof. The ecologicalpreparation comprises 60-70 parts of starch, 10-15 parts of humic acid, 2-5 parts of calcium superphosphate, 8-10 parts of a microbial agent, and 10-20 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 phosphate solubilizing bacteria, and a weight is 0-20% of the microbial agent. The preparation method for the ecological preparation comprises the following steps: putting raw material components of the ecological preparation in parts by weight into a stirrer, stirring and reacting, to obtain the ecological preparation. The ecological preparation can be independently used or compounded with an agriculture and forestry organic fertilizer for using. The ecological preparation is simple and convenient in operation, low in production cost, and capable of enabling an emergence rate of a sandy land plant to be improved by 50%or more.

Description

technical field [0001] The invention belongs to the technical field of ecological preparations, and in particular relates to an ecological preparation for promoting the growth of plants in desertified land and a preparation method thereof. Background technique [0002] Soil desertification generally refers to the process of turning good soil or usable land into sandy soil or land or even desert. The main processes of soil desertification are wind erosion and wind accumulation. In the surrounding areas of the desert, due to vegetation destruction or grassland overgrazing or reclamation into farmland, the soil becomes dry due to dehydration, soil particles are scattered, eroded by wind, and the content of fine particles decreases. After the wind has passed or weakened, the wind-blown sand particles gradually accumulate on the soil surface to make the soil sandy. Therefore, soil desertification includes the process of wind erosion of grassland soil and the process of wind-san...
