Abstract

The invention relates to tobacco plant growth promoting bacteria YC8 and an application thereof. The tobacco plant growth promoting bacteria is tobacco plant growth promoting bacteria YC8 and is classified and named as bacillus megaterium which is collected in General Microorganism Center of China Committee for Culture Collection of Microorganisms with the collection number CGMCC NO.9895 on 31st October, 2014. The tobacco plant growth promoting bacteria YC8 and the application have the advantages that the problem that difficultly-soluble potassium-containing silicate is converted into soluble potassium salt can be effectively solved, organophosphorus can be degraded, the utilization rate of fertilizers can be increased, the tobacco plant growth promoting bacteria YC8 can be effectively used for planting tobaccos, the growth of tobacco can be promoted, the yield can be increased, and the tobacco plant growth promoting bacteria YC8 is an important innovation on microorganisms and tobacco planting.

Description

technical field [0001] The invention relates to microorganisms, especially a tobacco rhizosphere growth-promoting bacterium YC8 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, soil nu...
