摘　　要：为了进一步提高名优绿茶的品质和产量,选择保靖黄金茶1号和白毫早2个特早生茶树品种为材料,研究了春剪秋控修剪技术对萌芽和产量的影响。结果表明:采用春剪秋控修剪技术,保靖黄金茶1号和白毫早春茶一芽一叶期分别比常规修剪技术(CK)提早18.0和17.7 d,一芽二叶期分别比CK提早16.7和16.3 d;保靖黄金茶1号和白毫早的一芽一叶百芽重分别比CK高41.13%和65.67%,发芽密度分别比CK高16.79%和13.18%,春茶鲜叶产量分别比CK增产111.60%和154.47%,其中一芽一叶百芽重和春茶鲜叶产量的差异达极显著水平,春茶发芽密度的差异达显著水平。In order to further improve the quality and yield of famous green tea,two extra early-growing tea cultivars,Baojing Huangjincha No.1 and Baihaozao,were selected as materials to study the effects of spring cutting and autumn control pruning technology on the germination period and yield of tea trees.The results showed that respectivly compared with CK pruned by the conventional pruning technology,the one bud and one leaf stages of Baojing Huangjincha No.1 and Baihaozao spring tea trees pruned by the spring cutting and autumn control pruning technology were 18.0 and 17.7 days earlier,the one bud and two leaves stages were 16.7 and 16.3 days earlier,the 100-bud weights(counting on one bud and one leaf)were 41.13%and 65.67%higher,the germination densities were 16.79%and 13.18%higher,and the yields of fresh leaves of both spring teas were 111.60%and 154.47%higher;furthermore,the differences of the 100-bud weight of one bud and one leaf and the yield of fresh leaves of the spring teas reached an extremely significant level,and the difference of the germination density of the spring teas reached a significant level.
