茶树七叶新梢与提高茶园经济效果之间关系的研究,近来引起科技人员的重视。我们作分析的材料,无性系“科尔赫达”(257号)和当地群体的七叶新梢,是在茶叶及亚热带作物研究所茶园中采集的。采下的新梢,分品种蒸3～5分钟以后,在60～70℃温度条件下干燥,进行固定。同时从七叶新梢上分出一芽二叶,其余的茎叶按各叶位分别 Research on the relationship between new shoots of tea leaves and the economic effects of tea plantations has drawn much attention from scientists and technicians. The material we analyzed, the clones of “Corcida” (No. 257) and the local group of new seven-leaf shoots, were collected in tea plantations in the Tea and Subtropical Crops Institute. Take the shoots, sub-varieties of steamed 3 to 5 minutes later, at 60 ~ 70 ℃ temperature conditions drying, fixed. At the same time from the new leaves buds split a bud two leaves, the rest of the leaves by leaf position respectively
