唐茜　李永泽　单虹丽摘　要　以川西茶区5个栽培品种为材料，调查分析了各品种春梢伸育的动态。结果表明，在川西海拔1060m的地域条件下，各品种的春梢生育期和生育强度有明显的差异，福鼎大白茶仍具早萌、展叶快、可早采的优良性状，名优茶开采期比其余品种早6～10天。5个品种的越冬芽从萌动到形成一芽一叶新梢需19～26天，活动积温150～220℃；形成一芽三叶新梢需37～53天，活动积温330～510℃。故高海拔茶园名优茶的开采期普遍较晚，应采取早萌高效的栽培技术措施，以便早采、多产名优茶原料。关键词　茶树品种　春梢　伸育动态　积温　名优茶中图分类号　S571.1 STUDY ON THE SPRING SHOOT GROWTH DYNAMIC OF 5 VARIETIES IN WEST-SICHUAN TEA AREA Tang Qian　Li Yongze　Shan Hongli (College of Forestry and Horticulture, Sichuan Agricultural University/Yaan, Sichuan, China 625014)
