Functional bacterial strain No.5 as well as cultivation method and application of bacterial preparation

Abstract

The invention discloses a functional bacterial strain No.5 as well as a cultivation method and the application of a bacterial preparation. The functional bacterial strain is preserved and stored in the CGMCC (China General Microorganism Conservation Center), has a register number of CGMCC No.3938 and a Latin scientific name of Pseudomonas brassicacearum. The functional bacterial strain can be used for promoting the growth of seedlings, improving the yield and the quality of tea and the fruit quality, resisting pathogens, decomposing inorganic and organic phosphorus into soluble phosphorus, improving the soil fertility and obviously improving the soil quality and can also grow in a culture medium of 7% NaCl.

Description

technical field [0001] The invention relates to a functional bacterial strain, in particular to a functional bacterial strain No. 5, its cultivation method and the application of the microbial agent. Background technique [0002] Since long-term use of chemical fertilizers and pesticides is likely to cause problems such as soil compaction, land degradation, and chemical fertilizer and pesticide residues, biological fertilizers have been rapidly developed to promote seedling growth, resist pathogenic bacteria, improve soil environment, and increase fertility. [0003] In the prior art, biological fertilizers have problems such as single function, unstable quality, and poor soil adaptability. Contents of the invention [0004] The purpose of the present invention is to provide a functional bacterial strain No. 5 with comprehensive functions, stable quality and good soil adaptability, its cultivation method and the application of bacterial agent. [0005] The purpose of the ...
