摘　　要：以不修剪或树冠面修齐作对照,设最大树幅处剪平、最大树幅处与冠顶(树冠面最高处)的垂直距离1/2处剪平等2个处理,比较对芽梢性状、鲜叶产量、茶叶品质的影响效应。结果表明:处理1每(33.3 cmX33.3 cm)X 10 cm叶层范围内春、秋茶发芽密度2年平均分别达154个和58个,显著或极显著高于对照;百芽重处理间的差异未达显著水平;处理1的春、秋茶产量显著或极显著高于对照;对照的乌龙茶花香显,味醇爽,汤色金黄明亮,平均加权得分高于其他处理0.1~1.5分,品质最佳;春茶酚氨比均高于对照。In preparation for a study on mechanized plucking of tea leaves from bushes at plantations,this experiment was designed with two pruning methods to determine their effects on the crown growth and quality of oolong tea.The pruning Treatment 1 was to trim a tea plant at its widest girth line,and Treatment 2 was to cut across the branches at half distance between the widest girth line and the crown tip(height of the plant).These treated plants were to compare with CK,which were either not being pruned or done by canopy surface pruning,on fresh leaf yield,bud shoot property and tea quality.The results indicated that(a)the 2-year average density of new shoots on a 33.3 cm width X 33.3 cm depth X 10 cm height tree branch area of the spring tea plants from Treatment 1 was 154,and 58 of the autumn tea;which were significantly or extremely significantly higher than those of CK;(b)the hundred-piece weights of tea shoots on tea plants did not significantly differ among the treatments;(c)Treatment 1 produced significantly higher yield of the spring tea and extremely significantly higher yield of the autumn tea than that of CK;(d)the brewed oolong tea from CK was better in quality with prominent flowery fragrance,refreshing taste,clear yellowish brown color,and an average weighted score 0.1～1.5 higher than the treated samples;and,(e)the phenol ammonia ratio of the spring tea from the treatments was higher than that of CK.
