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。
Five cultivars of tea in the west of Sichuan Province were used as materials to investigate the dynamics of spring shoot growth of all varieties. The results showed that under the geographical conditions of 1060 m above sea level in western Sichuan, there was a significant difference in spring growth period and fertility between different varieties. Fuding Dabai was still featured with early adorable, 6 to 10 days earlier than the rest of the breed. Five varieties of winter buds from sprouting to form a bud a leaf shoot 19 to 26 days, the activity accumulated temperature of 150 ~ 220 ℃; formation of a shoot three-leaf shoots need 37 to 53 days, activity accumulated temperature 330 ~ 510 ℃. Therefore, the high-altitude tea plantation tea production late generally late, should take early Meng efficient cultivation techniques and measures for early mining, prolific production of famous tea raw materials.
