摘　　要：经过连续4年的田间试验,比较了2次机采、重度机采、轻度机采和不机采对照等4个处理对白露毛尖茶产量和品质的影响。结果表明:2次机采和重度机采处理显著增加秋季茶芽密度和1芽1叶初展鲜叶产量,显著降低单个芽头的平均重量、长度及符合加工白露毛尖茶芽大小标准的茶芽合格率;符合加工白露毛尖茶芽大小标准的1芽1叶初展鲜叶产量轻度机采处理最高;内含成分分析表明,4个处理秋季1芽1叶初展鲜叶均适宜加工白露毛尖茶,以不机采对照处理感官品质最好。试验表明适度机采可提高秋季白露毛尖茶鲜叶产量,不机采或轻度机采可获得更多优质的白露毛尖茶鲜叶原料。Through a series of 4-year field experiment in hilly tea plantations,the effect of double machine-plucking,heavy machine-plucking,light machine-plucking and no machine-plucking on yield and quality of Bailumaojian tea was examined.The results show that：double and heavy machine-plucking increase bud density and one-leaf and one-bud （fold） yield in autumn.They also remarkably decrease bud weight,length and fitting ratio for processing of Bailumaojian tea.Among the 4 treatments,light machine-plucking has the largest one-leaf and one-bud （fold） yield fitting for processing famous Bailumaojian tea.Chemical analysis shows that leaves of four treatments are all fit for processing famous Bailumaojian tea,while those of no machine-plucking treatment have the best organoleptic quality.The study shows that proper machine-plucking increases yield of Bailumaojian tea in autumn,whereas no or light machine-plucking yields the best quality fresh tea leaf.
