根据一般分析,在茶树鲜叶细胞液中含有大量含氮和不含氮化合物。这些物质都是茶树生理代谢的产物。生理代谢随着季节是周期性变化,这些变化与茶树的生长、生殖、抗寒、抗旱有着密切的关系。因此,探讨细胞液各个时期浓度的变化,是鉴定品种,了解茶树生育消长规律的一种重要手段。一、六个品种细胞液浓度的测定我们选定一般生产中常见的六个品种,即福鼎、云大、牛皮、安徽一号、黔湄303和阔叶藤作为观察测试对象。于每月28日在选定的茶树上取一芽四叶上第四张叶片10张,擦净晾干,剪碎后挤压,取叶汁
According to the general analysis, a large amount of nitrogen-containing and nitrogen-free compounds are contained in the tea leaf fresh cell liquid. These substances are the product of the physiological metabolism of tea trees. Physiological metabolism changes cyclically with the season. These changes are closely related to the growth, reproduction, cold resistance and drought resistance of tea trees. Therefore, it is an important method to identify the varieties and to understand the law of the growth and decline of the tea plantation. First, the determination of the concentration of six cell lines of liquid We selected six common species commonly found in production, that is, Fuding, cloud big, leather, Anhui, Qianmei 303 and broad-leaved vine as the observation test object. On the 28th of each month in the selected tea tree to take a four leaves on the fourth leaf 10, wipe dry, squeezed after shearing, take leaf juice
