Data were expressed as mean ± standard error (n = 4). The data within a column of each trial with a same letter did not differ significantly at Fisher’s least significant difference test (LSD) and Duncan’s significance level 0.05. CK: NPK fertilizer; O: NPK fertilizer + organic fertilizer; B: NPK fertilizer + bioorganic fertilizer; S: NPK fertilizer + soil disinfection; S+B: soil disinfection + NPK fertilizer + bioorganic fertilizer.
