Abstract:

In order to explore the application effect of microbial fertilizer in the cultivation of bayberry, Dongkui bayberry was used as the test material, and four treatments were set up, including control (no microbial fertilizer, CK), treatment A (containing Bacillus mucilaginosus LXB4001 and new Bacillus subtilis), treatment B (containing Bacillus amyloliquefaciens) and treatment C (containing LV Bacillus subtilis), to study the effects of microbial fertilizers on the pH value, enzymes activities, soil fertility in 0-20 cm soil layer and leaf chlorophyll, nitrogen, phosphorus and potassium content. The results showed that the treatment C could significantly (P<0.05) reduce soil pH value than the CK. Compared with the CK, application of microbial fertilizers could improve soil nutrients, with the contents of soil alkali-hydrolyzable nitrogen, available phosphorus, available potassium significantly increased by 18.2%-45.0%, 43.7%-156.3%, 24.0%-40.8%, respectively. It could also promote the accumulation of chlorophyll and nitrogen, phosphorus and potassium in leaves. Except for the leaf phosphorus content of treatment B, the contents of total chlorophyll, nitrogen, phosphorus and potassium in the other treatments were significantly increased by 27.5%-42.4%, 17.5%-33.2%, 11.7%-13.6% and 14.6%-32.9%, than the CK, respectively. Based on the comprehensive evaluation by principal component analysis, it was shown that the comprehensive score of four treatments was decreased as treatment A > treatment B > Treatment C > CK. In summary, microbial fertilizer was helpful to improve soil properties, enhance soil fertility, improve soil sustainable production capacity, which was beneficial to plant growth. Under the experiment conditions, treatment A exhibited the best effect.
