- Abstract
[Objective] This study was aimed to explore the effects of Bacillus amyloliquefaciens biofertilizer on tea yield and quality. [Method] The field plot experiment was conducted with the biofertilizer treatments and control to investigate 100-bud weight and main biochemical components. [Result] The treatments by Bacillus amy-loliquefaciens biofertilizer, which was fermented using sweet potato starch wastewater (SPSW) as culture medium, improved 100-bud weight and tea quality significantly under the concentration of 0.8x108, 1.6x108 and 3.2x108 cfu/ml with the dose of 1 L/m2 for 4 times. At the optimum concentration of 1.6x108 cfu/ml, the biofertilizer treatment increased the 100-bud weight by 22.3%, water extracting materials by 21.9%, amino acids content by 8.83%, tea polyphenol content by 9.76%, and decreased theine content by 8.32%, respectively. Compared with the control, there was no significant difference between the SPSW treatment and the control. [Conclusion] The production of the B. amyloliquefaciens biofertilizer could consume SPSW, and the application of the biofertilizer could improved the tea yield and quality, which provided references for the development of ecological agriculture.
