Plant growth-promoting rhizobacteria (PGPR) are known to have the effect of promoting plant growth. In this paper, three PGPR strains were selected from the previous work, which had plant growth-promoting activities such as phosphate solubilization, nitrogen fixation, phosphorus mobilization, etc. These strains named FJS-3( Burkholderia pyromania ), FJS-7( Pseudomonas rhodesiae ), and FJS-16( Pseudomonas baetica ), respectively, were prepared into solid biological agents. Three widely planted commercial crops (tea plant, tobacco, and chili pepper) were selected for PGPR growth promotion verification. The results showed that the new shoots of tea seedlings under PGPR treatment were much more than the control. We also used tobacco, another important crop in Guizhou, to test the growth-promoting effect of individual bacteria, and the results showed that each of them could promote the growth of tobacco plants, and FJS-3( Burkholderia pyrrocinia ) had the best effect. In addition, we carried out experiments on tobacco and pepper using multi-strain PGPR, the tobacco plants' height, fresh, and root weight increased by 30.15%, 37.36%, and 54.5%, respectively, and the pepper plants' increased by 30.10%, 56.38% and 43.18%, respectively, which both showed significantly better effects than that of a single strain. To further test the field performance, field trials were carried out in a mature Longjing43 tea plantation in Guizhou. There were four treatments: no fertilization (T 1 ), combined application of PGPR biological agent and compound fertilizer (T 2 ), only application of PGPR (T 3 ), and only application of compound fertilizer (T 4 ). In terms of yield, grouped with or without PGPR, there was a 15.38% (T 2 :T 4 ) and 92.31% (T 3 :T 1 ) increase between them, respectively.…
