磷是茶树主要营养元素之一,它有促进氨基酸活化和蛋白质合成的作用。正确地施用磷肥能夠提高茶树生活力,增加茶叶产量,改进制茶品质;但是,如果施用不当,使有机物质正常轉化受到抑制或破坏,不仅没有增产效果,甚至还有減产可能。因此,研究茶园中合理施用磷肥,是一項具有生产意义的重要課題。1955年起,我所对茶园施用磷肥問題,进行了一系列的田间試驗。现将这些試驗結果作如下的分析与闡述。
Phosphorus is one of the main nutritional elements of tea tree, it has the role of promoting amino acid activation and protein synthesis. Proper application of phosphate fertilizer can improve the vitality of tea trees, increase the yield of tea and improve the quality of tea making. However, if applied improperly, the normal transformation of organic matter will be inhibited or destroyed, not only without increasing yield, but also decreasing yield. Therefore, the study of rational use of phosphate fertilizer in the tea garden is an important issue with a productive significance. Since 1955, I conducted a series of field experiments on the problem of applying phosphate fertilizer to the tea plantations. Now these test results are analyzed and elaborated below.
