Streptomyces halotolerant, its agent and its application in promoting plant growth

Abstract

Streptomyces olivaceus strain GDMCC No.60272. A microbial inoculant prepared from the above strains. The preparation method of the above-mentioned microbial bacterial agent and the application of the prepared microbial agent in promoting the growth of plants in saline soil environment. The streptomyces strain of the invention has high activity and stability, and can effectively promote the growth of plants in saline soil environment. The microbial agent of the invention has simple preparation method, low production cost, no pollution and is suitable for large-scale application. Irrigation of plants with the microbial agent of the present invention can promote the growth of plants in the saline soil environment, thereby improving the saline soil, with low cost, simple use, no pollution, no toxin residue, and no harm to humans, animals and the environment.

Description

technical field

[0001] The present invention relates to microorganisms, microbial inoculum, preparation and application thereof, in particular to a strain of Streptomyces olivaceus (Streptomyces olivaceus) strain GDMCC No.60272, microbial inoculum prepared by the strain, its preparation method and Application of the prepared bacterial agent in promoting plant growth. Background technique

[0002] Soil salinization is one of the main factors affecting agricultural production globally. In recent years, due to the influence of human activities and natural factors, the problem of soil salinization has become increasingly serious. According to incomplete statistics, the global salinized soil area is about 8.3×10 9 hm 2 , and our country also has about 6.67×10 6 hm 2 The salinized arable land accounts for about 25% of the arable land area, and it tends to increase year by year. Soil salinization mainly refers to the phenomenon or process of soluble salt accumulation on the so...
