Problems solved by technology

Improvement of saline soil can be done by measures such as drainage and salt washing, or by planting green manure, applying organic manure, or planting rice and other crops to improve its salt; although these methods have certain effects on the improvement of saline-alkaline soil, the effect is not stable, and in In practical application, a large amount of manpower, material and financial resources input has greatly increased the cost of this measure

Abstract

The invention belongs to the technical field of microbial preparations, and relates to a microbial preparation for facilitating saline and alkaline land plant growth and a preparation method of the microbial preparation. The microbial preparation comprises, by weight, 60-70 parts of starch, 8-10 parts of microbial agents and 20-32 parts of algal polysaccharides. The microbial agent is Brevibacterium sp.TS22 which is domesticated at low altitude and at the normal temperature, and the collection number is CGMCC 16576. The microbial agents include mixed agents of halophilic bacteria and bacilli,and the mixed agents account for 0-20% of the weight of the microbial agents. The preparation method of the microbial preparation includes the steps: feeding raw materials of the microbial preparationinto a stirrer; performing reaction in a stirred manner to obtain the microbial preparation for facilitating growth of plant root systems. The microbial preparation is separately used or compounded with agriculture and forestry organic fertilizers to be used. The microbial preparation is simple to operate and low in production cost and can effectively facilitate growth of saline and alkaline landplants.

Description

technical field [0001] The invention belongs to the technical field of microbial preparations for plant growth, and in particular relates to a microbial preparation beneficial to plant growth in saline-alkali land and a preparation method thereof. Background technique [0002] Saline-alkali soil is the general term for saline soil and alkaline soil among the people. The soil salinity is above 0.1%-0.2%, or the soil colloid absorbs a certain amount of exchangeable sodium, and the alkalization degree is above 15%-20%, which will seriously affect the normal growth of crops. Such soil belongs to saline-alkali soil. Saline-alkali soil is also called saline soil. According to incomplete statistics, there are about 950 million hectares of saline-alkali land in the world; China's saline-alkali land is mainly distributed in the inland arid and semi-arid areas of North China, Northeast China and Northwest China, and also in coastal areas along the eastern coast. [0003] Salt stress...
