Abstract

The invention relates to tobacco growth-promoting rhizobacteria YC5 and an application thereof. The tobacco growth-promoting rhizobacteria are the tobacco growth-promoting rhizobacteria YC5, and are classified to be named as Bacillus simplex; and the tobacco growth-promoting rhizobacteria YC5 are collected in the General Microbiological Center of China Committee for Culture Collection of Microorganisms on October 31, 2014, and a collection number of the tobacco growth-promoting rhizobacteria YC5 is CGMCC No.9893. By adopting the tobacco growth-promoting rhizobacteria YC5 disclosed by the invention, the problem of converting difficultly-soluble potassium-containing silicate into soluble potassium salt can be effectively solved, organic phosphorus can be degraded, and the utilization rate of fertilizers can be improved; and the tobacco growth-promoting rhizobacteria YC5 can be effectively applied to the cultivation of tobaccos, can be used for promoting the growth of the tobaccos and improving the yield, and is a great innovation of microorganism and tobacco planting.

Description

technical field [0001] The invention relates to microorganisms, in particular to a tobacco rhizosphere growth-promoting bacterium YC5 and its application. Background technique [0002] Fluvo-aquic soil is the soil formed by river sediments affected by groundwater movement and farming activities. It is named after the night tide phenomenon. In China, it is mostly distributed in the alluvial plains of the middle and lower reaches of the Yellow River, the plains of Jiangsu and Anhui to the south, and the river, lake plains and deltas of the middle and lower reaches of the Yangtze River Basin. The distribution area of ​​fluvo-aquic soil is flat, with deep soil layer, abundant water and heat resources, and wide variety of seed production. It is the main dryland soil in my country and is rich in grain and cotton. However, the Huang-Huai-Hai Plain, where the fluvo-aquic soil is the largest, suffers from frequent droughts and floods, as well as saline-alkali hazards. In addition, s...
