摘　　要：探明氨基酸叶面肥对黄化茶树夏秋茶产量和品质的影响,为黄化茶树夏秋茶提质增产提供技术支撑。以黄化茶树品种‘中黄3号’为试材,设置不施叶面肥(CK)、喷施氨基酸水溶性叶面肥(氨基酸≥100 g/L、锌≥10 g/L、硼≥100 g/L,T1)、喷施活性氨基酸叶面肥(氨基酸≥100 g/L、有机质≥130 g/L、锌+硼≥100 g/L,T2)、喷施茶树叶面肥(氨基酸≥100 g/L、锌+硼≥100 g/L,T3)、水溶喷施1.8%尿素(总氮≥46.4%,T4)5个处理,比较分析各处理对夏秋茶产量、品质的影响。结果表明,施叶面肥处理的发芽密度、一芽二叶百芽鲜重分别大于、显著大于CK。CK产量最低,T1、T2、T3的产量分别高于T4,T1和T3产量分别略高于T2。各处里间的水浸出物和咖啡碱含量无显著差异。CK的酚氨比最高,T2的酚氨比最低,T1和T2的酚氨比显著低于CK和T4,而CK、T3、T4之间无显著差异。研究表明,夏秋季T1、T2能较好地提高黄化茶树茶叶产量,改善绿茶品质,T2的综合效果更好。To provide technical support for increasing yield and improving quality of etiolated tea plant(Camellia sinensis)in summer and autumn,the etiolated cultivar‘Zhonghuang 3’was selected to study the effects of amino acid foliar fertilizer on tea yield and quality.Five treatments were set up,including no foliar fertilizer(CK),spraying amino acid water-soluble foliar fertilizer(amino acid≥100 g/L,Zn≥10 g/L,B≥100 g/L,T1),spraying active amino acid foliar fertilizer(amino acid≥100 g/L,organic matter≥130 g/L,Zn+B≥100 g/L,T2),spraying special foliar fertilizer for tea plant(amino acid≥100 g/L,Zn+B≥100 g/L,T3),and spraying 1.8%urea(total N≥46.4%,T4).The results showed that the budding density and the 100-bud fresh weight of one bud and two leaves under foliar fertilizer treatments were higher or significantly higher than those of CK,respectively.The yield of CK was the lowest.The yield of T1,T2 and T3 was higher than that of T4,while the yield of T1 and T3 was slightly higher than that of T2,respectively.There was no significant difference in water extracts and caffeine content among all treatments.The ratio of tea polyphenols to free amino acids(TP/AA)of CK was the highest,while that of T2 was the lowest.TP/AA of T1 and T2 was significantly lower than that of CK and T4,while no significant difference was observed among that of CK,T3 and T4.The study suggested that T1 and T2 could contribute more to increasing the yield and improving the quality of green tea in summer and autumn,while T2 had better overall quality.
