茶树是以收获鲜叶为栽培目的的,采摘是茶叶收获的主要手段。研究采摘后茶树体内物质的生化反应对指导合理采茶具有积极的意义。近几年来,作者对采摘茶树与自然生长茶树的生化问题进行了一些研究,根据研究结果,阐述采摘对茶树生化成分的影响。茶树95％的生物产量是依靠光合作用来取得的,而叶片是进行光合作用最基本的部位,故称为茶树的营养器官。长期来人们对采摘的一些问题进行了大量的研究,试图利用合理的采摘技术措施激发茶树的生理活动,促进新陈代谢。采摘解除了茶树新梢生长的顶端优势,促进了侧枝和芽叶的生长,同时也打破了茶树地上部和地下部的生理平衡,从而引起茶树机体内部的一系列生理生化变化。如果不采摘,茶树生理机能会受到一定影响,新陈代谢只能维持在一个低水平上,有机物质的积累相应就少。因此,在某种程度
Tea is the harvest of fresh leaves for cultivation purposes, picking is the main means of tea harvest. Studying the biochemical reaction of the material in tea plant after picking has a positive meaning to guide the rational picking of tea. In recent years, the author has made some researches on the biochemical problems of picking tea trees and naturally growing tea trees. According to the results of the research, the author expounds the influence of picking on the biochemical components of tea trees. 95% of the biological yield of tea tree is obtained by photosynthesis, and the leaves are the most basic parts of photosynthesis, it is called the vegetative organs of tea tree. For a long time people have done a lot of research on some of the picking problems, trying to use reasonable picking techniques to stimulate the physiological activity of tea tree and promote metabolism. Picking removes the top advantage of the growth of tea shoots, promotes the growth of the branches and shoots, and at the same time, breaks the physiological balance of above and below the tea plant, causing a series of physiological and biochemical changes inside the tea plant. If you do not pick, the physiological functions of tea trees will be affected, the metabolism can only be maintained at a low level, the corresponding accumulation of organic matter less. So, to some extent
