一、前言 磷是构成植物细胞核酸、磷脂等重要物质的组成部分,在植物代谢过程和能量的传递中起一定的作用。植株中存在的无机磷,还具有保持细胞液浓度和缓冲的作用。因而加强茶树的磷素营养,可以加强光合磷酸化过程,促进叶片营养物质的外运,从而增强叶片的光合能力,促进茶树营养器官的生长,增加茶叶产量。充足的磷素供应对增加新梢单宁和糖类、蛋白
I. INTRODUCTION Phosphorus is an integral part of important substances such as plant cell nucleic acids, phospholipids, etc. It plays a role in plant metabolism and energy transfer. The presence of inorganic phosphorus in plants also has the effect of keeping the concentration and buffer of the cytosol. Therefore, strengthening the phosphorus nutrition of tea tree can enhance photosynthetic phosphorylation and promote the transport of leaf nutrients, thereby enhancing the photosynthetic capacity of leaves, promoting the growth of vegetative organs of tea tree and increasing the yield of tea. Adequate supply of phosphorus to shoots and tannins, sugars, proteins
