Novel strain of streptomyces fradiae and application thereof

Abstract

The invention discloses a novel strain CLIMAX-VSF of streptomyces fradiae. The preservation number of the novel strain is CGMCC No. 5133; the preservation date is August 12, 2011; and the preservation department is China General Microbiological Culture Collection Center. The invention further discloses a microbial inoculum containing the novel strain. The novel strain CLIMAX-VSF of the streptomyces fradiae, which is provided by the invention, has quite obvious performances of disease resistance, nitrogen fixation, phosphate solubilization and somatotropin secretion. By using the strain, the germination rate and the growth speed in a seedling stage can be obviously improved under the condition that nutrients are not added to soil, and furthermore, diseases in the seedling stage and a growth period are obviously inhibited. On the aspect that the strain is used for the mixed preparation and the synergy of a fertilizer, the strain shows to have the favorable effect of activating soil nutrients and the performance of resisting a plurality of cultivation obstacles.

Description

technical field [0001] The invention belongs to the field of soil fertilizer, and in particular relates to an agricultural microbial preparation and its application. Background technique [0002] White agriculture refers to the industrial new agriculture of microbial resource industrialization, and usually refers to the application of microbial fermentation engineering in agriculture. Agricultural production requires soil to provide nutrients for crop growth and a living environment. The application of chemical fertilizers has played a key role in increasing agricultural incomes for many years. However, due to the long-term application of chemical fertilizers, the soil beneficial microbial flora is damaged, the supply of organic fertilizer is insufficient, and the proportion of various nutrients is out of balance, resulting in different degrees of damage to the farmland ecological environment, soil physical and chemical properties and soil microbial flora. The current statu...

Problems solved by technology

However, due to the long-term application of chemical fertilizers, the soil beneficial microbial flora is damaged, the supply of organic fertilizer is insufficient, and the proportion of various nutrients is out of balance, resulting in different degrees of damage to the farmland ecological environment, soil physical and chemical properties and soil microbial flora. The current status of soil resources in my country urgently needs to solve the problem of soil being gradually destroyed through artificial measures to ensure the level of agricultural planting and the quality of crop products.
