我国茶区春茶产量在全年茶叶产量中占有很大的比重,长江中下游茶区可达全年总产的一半以上。春茶的来源是由越冬芽萌发伸育的嫩梢芽叶。因此,开展茶树越冬芽和春梢伸育规律的研究具有很重要的实际意义,已引起茶叶工作者的重视。但是,以往的研究多偏重于对越冬芽萌发后新梢的观察,对越冬芽本身,尤其是荫发前芽体内部 The output of spring tea in tea area in our country occupies a large proportion in the output of tea in the whole year. The tea area in the middle and lower reaches of the Yangtze River reaches more than half of the annual output. The source of spring tea is the shoot shoots of young shoots that are sprouted by the overwintering buds. Therefore, the study on the law of overwintering buds and spring shoots of tea has very important practical significance, which has attracted the attention of tea workers. However, previous studies mostly focused on the observation of the shoots after the germination of the overwintering buds. The overwintering bud itself, especially the interior of the bud before the bud
