Abstract

The invention relates to tobacco plant growth promoting bacterium TC6 and application thereof. The tobacco plant growth promoting bacterium is tobacco plant growth promoting bacterium TC6, has the classification name of bacillus subtilis, is preserved at China General Microbiological Culture Collection Center since 31st, October, 2014, and has the preservation number of CGMCC No. 9894. Tobacco plant growth promoting bacterium TC6 is capable of effectively converting difficultly-dissolved potassium-containing silicates into dissolvable potassium salts, decomposing organic phosphorus and improving fertilizer utilization rate, is effectively applied to tobacco cultivation, promotes tobacco growth and improves output, and is a great innovation for microbe and tobacco plantation.

Description

technical field [0001] The invention relates to microorganisms, in particular to a tobacco rhizosphere growth-promoting bacterium TC6 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...
