茶叶生产,当前要注意的是提高产量的同时提高质量,这个问题牵涉的范围极广,不仅涉及产制运销,还牵涉到生产结构和有关政策。这里专就光能利用和矿质营养来讨论这问题。从茶叶内含成分来说,决定茶叶产量的主要化学物质是蛋白质、单宁(单守旧称:是高等院校统一教材《制茶学》和《茶叶生物化学》的多酚类化合物的学名下同——编者注)物质、纤维复合体。在茶叶中粗蛋白质的含量约占干物量的25—35％,单宁物质
At present, it is necessary to pay attention to raising the output while improving the quality of tea production. The scope of this issue is extremely wide. It involves not only the production and distribution but also the production structure and related policies. Here to discuss the issue of light energy use and mineral nutrition. From the content of tea, the main chemical substances that determine the yield of tea are protein and tannin (unilatly said to be under the scientific name of polyphenolic compounds of “tea science” and “tea biochemistry” Same - editor’s note) material, fiber complex. The content of crude protein in tea accounts for about 25-35% of dry matter, tannin material
