(一)前言茶树原生于亚热带大森林里,在长期系统发育过程中,形成了喜温、喜湿、耐荫生态遗传特性。因而,创造一个适于茶树生长的生态环境,越来越显得重要了。建国以来,我省先后在丘陵地带建造了很多新茶园。过去我们总是认为:这些地区茶树的鲜叶品质差,产量上不去,是由于建园基础不好,肥培管理不够,这仅是从狭义而言。从广义理解,主要原因是茶园生态条件劣变,绝大多数茶园,共同特点是环境条件不理想,即茶园坡度大,植被遭破坏,水土流失严重,土壤肥力低,茶树长势弱,这 (A) Foreword Tea tree was born in a large subtropical forest, in the long-term phylogenetic process, the formation of a warm, wet, shade-resistant ecological genetic characteristics. Therefore, it is more and more important to create an ecological environment suitable for the growth of tea trees. Since the founding of the PRC, our province has built a lot of new tea gardens in the hilly areas. In the past we always thought that the fresh leaf quality of tea trees in these areas was poor and the yield did not rise. This was due to the poor foundation of the park and the inadequate management of fertilizer cultivation, which is only narrowly defined. From a broad sense, the main reason is the deterioration of the ecological conditions of the tea plantations, the vast majority of tea gardens, the common feature is the unsatisfactory environmental conditions, that is, the tea plantation gradient, vegetation damage, serious soil erosion, low soil fertility, tea growing weak, which
