椿-茶天然混交茶园生理生态研究初报

Ecophysiological Studies on Natural Mixedgarden of Chinese Toona-Tea

香椿与茶树天然混交茶园与全日照茶园相比；生态环境发生了一定的变化，日照强度、日间温度及风速均有不同程度的下降，空气湿度有所提高；春茶芽叶氨基酸含量、幼叶叶绿素含量和春梢生长量均有增加，茶多酚、碳水化合物有不同程度降低；不同生境下茶树叶片解剖结构也存在一定的差异。

Compared with the pure tea garedn,the toona-tea mixed garden was better both in micro-ecoconditions and in physiochemical status of tea.The intensity of radiation,day time temperature and wind velocity were less while the air humidity was higher;the amino acids and chlorophyll contents in spring tea bud were higher but the contents of tea polyphenol and carbohydrate were lower;the spring sprout grew more fast;and there were also some anatomical differences of the leaves of tea between the two types
