摘　　要：[目的]研究一种新型液体有机肥对水仙乌龙茶茶叶品质和茶园土壤主要营养成分的影响。[方法]以水仙乌龙茶树品种为试材,研究该有机肥对水仙乌龙茶产量、内含生化成分、感官品质及茶园土壤主要营养成分的影响。[结果]T1(喷施A+B酵素)与CK相比,二者的发芽密度和百芽重相对变化不明显,但T1乌龙茶的水浸出物和茶氨酸的含量均高于CK,且水浸出物与CK呈极显著差异;另外,T1和CK的乌龙茶感官审评分别为90.75和90.05分,但T1的外形和香气表现均优于CK;另外,T1土壤中速效磷和有机质含量均高于CK,仅从有机质含量看,T1与CK分别为2.17和1.83 g/kg,二者呈极显著差异。[结论]该研究为该液体有机肥的推广应用提供科学依据。[Objective]To analyze effect of new type of liquid organic fertilizer on oolong tea quality and soil main nutrient components.[Method]Taking Shuixian tea plant as test material,the effects of the organic fertilizer on the yield of oolong tea,including biochemical components,sensory quality and main nutrient components of the soil in the tea garden were studied.[Result]The germination density and the 100-bud weight of T1 were not obvious compared with CK,but the content of tea water extract and theanine in the T1 tea was higher than CK,and tea water extract was very significant with respect to CK.The sensory evaluation of oolong tea of T1 and CK was 90.75 and 90.05,respectively,but the appearance and aroma of T1 were better than CK.In addition,the content of available phosphorus and organic matter in T1 soil was higher than CK.For organic matter in soil,T1 and CK were 2.17 and 1.83 g/kg respectively.[Conclusion]The study can provide scientific basis for the promotion and application of the liquid organic fertilizer.
