摘　　要： 研究了夏剪、冬剪两种轻修剪模式对茶假眼小绿叶蝉种群及茶叶产量、品质的影响。结果表明,1~4月,叶蝉数量少,对茶树为害极轻,虫口密度以夏剪稍高于冬剪;在春茶结束后即实施夏剪,6~10月间其虫口密度明显低于冬剪,表明在叶蝉为害高峰期之前,采取轻修剪措施可有效控制虫口密度,减少虫害损失。不同轻修剪模式对茶叶产量影响较明显,夏剪的春、夏茶产量分别比冬剪高21.3%~36.5%、6.61%~26.3%,对茶叶品质也有明显影响。 The effects of two different light pruning modes of summer-pruning and winter-pruning to smaller green leafhopper population dynamics,tea yields and quality were studied.Results showed that,from Jan.to Apr.,leafhopper population of summer pruning mode was slightly higher than that of winter pruning mode,but at the end of May,after the implementation of summer pruning,from Jun.to Oct.,its population was apparently lower than that of winter pruning model,so timely undertake light pruning can effectively depress the leafhopper population before its population peak,reduce its damage to tea plants.Different pruning mode effected on tea yields obviously,tea yields of summer pruning mode were higher than winter pruning mode of 21.3%~36.5%,6.61%~26.3%,and also had effects on tea quality obviously.
