Abstract:

This pepper was to study the effects of distillers lee organic fertilizer on green Meitancuiya tea,so as to provide theoretical basis for the scientific application and popularization of distillers lee organic fertilizer.A field experiment was conducted to study the effects of distillers lee organic fertilizer(CK: no fertilizer;FP: farmers practice;JZ1: distillers lee organic fertilizer of 750 kg/ha;JZ2: distillers lee organic fertilizer of 2 250 kg/ha;JZ3: distillers lee organic fertilizer of 3 750 kg/ha;JZ4: distillers lee organic fertilizer of 9 000 kg/ha) on the yield,yield composition,quality and nutrient accumulation of tea.The results showed that the application of distillers lee organic fertilizer increased the yield of fresh tea by 2.58%-7.52%(2020)and 0.67%-11.92%(2021),the yield of dry tea increased by 5.18%-13.90%(2020)and 4.21%-19.62%(2021)compared to the FP treatment,with the highest yield in the JZ3 treatment.Application of distillers lee organic fertilizer increased the bud density and 100-bud weight of green tea,and also increased the amino acid content of green tea by 2.35%-12.60%(2021),and reduced the phenol-ammonia ratio,which was beneficial to improving the quality of green tea.Compared with the FP treatment,the application of distillers lee organic fertilizer increased the accumulation of nitrogen,phosphorus and potassium.The application of distillers lee organic fertilizer can increase the yield and quality of Meitancuiya tea,and 2 250-3 750 kg/ha can be recommended as the optimal application rate of distillers lee organic fertilizer for green tea cultivation and planting in Meitancuiya tea.

Key words: Green tea, Distillers lee organic fertilizer, Yield, Quality, Nutrient accumulation
