Different lowercase letters after the data represent the significant difference among the 5 treatments at p < 0.05. Conventional: conventional chemical fertilization; CK: fertilized with basic fertilizer containing NPK fertilizers and composted cow manure; B. cepacia ISOP5: fertilized with basic fertilizer and then applied with suspension of strain B. cepacia ISOP5; R. palustris ISP-1: fertilized with basic fertilizer and then applied with suspension of strain R. palustris ISP-1; MB, fertilized with basic fertilizer and then applied with suspensions of B. cepacia ISOP5 and R. palustris ISP-1.
