摘要: 在丘陵茶树上应用2,3-环氧丙酸钾,能提高光合速率,增加一芽一叶、一芽二叶和一芽三叶的干物质积累,以及茶叶内水浸出物、氨基酸、茶多酚等主要成分的含量,从而获得茶叶增产、增质的作用。实验结果表明:一定浓度的2,3-环氧丙酸钾具有增强光合速率,加速光合产物输出进程,促进越冬留养叶的光合同化产物向新梢芽、叶运输、积累与分布的效应,为2,3-环氧丙酸钾增产优质提供生理依据。它的应用将为丘陵茶的高产优质开辟一条新途径。

Abstract: It was shown that 200 mg/L potassium 2,3epoxypropionate sprayed on tea trees growing in hilly areas could obviously raise the photosynthetic rate,increase the dry matter accumulation of buds with one leaf, two leaves, and three leaves, and raise the main compos ition contents of water extract, amino acids, and polyphenols in tea leaves. Therefore, the yield and quality of tea produced in hilly areas were raised and improved by potassium 2,3epoxypropionate.
