茶园杉木防护林带生态效应的研究

茶树在系统发育过程中,形成了喜荫、喜温、喜湿的特性。单一茶园种植的茶树处于阳光的直射状态,光温条件不适合茶树生长发育的要求,茶树生长不良,降低茶叶产量和品质,并引起茶园土壤侵蚀,茶园生态环境不断恶化。据资料报道,茶园间种梨、柿、板栗、杨梅、橡胶、湿地松等植物,形成各种不同类型的生态茶园,改善了光温条件,获得较

Ecological Effect of Chinese Fir Shelterbelt in tea Plantations.

A new type of ecological community is established by interplanting Chinese fir (Cunninghamia lanceolata) shelterbelt in tea plantations on mountainous lands. Through investigation and analysis on various parameters about tea tree, Chinese fir, soil and atmosphere, the results indicate that this kind of community can improve ecological environment in tea plantations and quality of tea-leaves, and raise per unit yield of tea. It is a new way for establishing better ecological tea plantations on mountainous lands of southern China, with tea trees as the main body and Chinese fir as protective shield and with combined development of tea and Chinese fir.
