[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 Bacil us amy-loliquefaciens biofertilizer, which was fermented using sweet potato starch wastewa-ter (SPSW) as culture medium, improved 100-bud weight and tea quality significant-ly under the concentration of 0.8×108, 1.6×108 and 3.2×108 cfu/ml with the dose of 1 L/m2 for 4 times. At the optimum concentration of 1.6 ×108 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 de-creased theine content by 8.32%, respectively. Compared with the control, there was no significant difference between the SPSW treatment and the control. [Con-clusion] The production of the B. amyloliquefaciens biofertilizer could consume SP-SW, and the application of the biofertilizer could improved the tea yield and quality, which provided references for the development of ecological agriculture.展开更多
