研究了苦丁茶的生物学特性,在杭州气候条件下,苦丁茶100％顶芽萌动期在4月20日～4月25日,5月30日后逐渐形成驻芽,在自然生长条件下,每年只长一轮新梢,从100％顶芽萌动到驻芽形成期间,新梢生长前速后缓,新稍长度的倒数(Y)与时间天数的倒数(X)呈极显著的正相关,顶芽的萌动期与生长速度主要受气温和日照条件的影响。100％顶芽萌动后20～25天为苦丁茶适采期。从其叶结构的切片观察,苦丁茶叶肉组织中未发现石细胞和单酸钙结晶等成份,海棉组织具有较大空腔。与茶叶(Tea)的结构有明显的不同。
The biological characteristics of Kuding tea were studied. Under the climatic conditions of Hangzhou, 100% of the top buds of Kudingcha germinated gradually from April 20 to April 25, and after May 30, buds gradually formed. Under natural growth conditions , With only one round of new shoots per year. During the bud formation from 100% of the top buds, the shoots were slowed before growth, and the reciprocal of the new length (Y) was significantly positive with the reciprocal of the days (X) Related, the bud bud germination period and growth rate are mainly affected by temperature and sunlight conditions. 100% top bud sprouting 20 to 25 days for Kudingcha fit period. From the observation of its leaf structure, no components of stone cells and calcium mono-calcium crystals were observed in the tissues of Kudingcha. The sponge tissue had a large cavity. And the structure of tea (tea) there is a clear difference.
