钾是茶树主要的营养元素之一,对茶叶的产量和品质影响较大。在生产茶园中往往由于偏施氮肥和酸性肥料,使土壤中的钾素越来越小,同时随着茶树年龄的增长,茶园土壤向酸化发展,又加剧土壤中钾的淋失,使茶园逐渐缺钾。据英红华侨茶场1980年对15,000多亩成龄茶园进行土壤普查的结果,发现有67.4％以上的茶园土壤缺钾,可见大部分茶园是需要施用钾肥,才能保证高产优
Potassium is one of the main nutritional elements of tea tree, which has great influence on the yield and quality of tea. In the production of tea plantations are often due to partial nitrogen fertilizer and acid fertilizers, so that the soil of potassium is getting smaller and smaller, at the same time as the tea age, the development of acidification of tea garden soil, but also aggravate the leaching of potassium in the soil, so that tea gradually Potassium deficiency. According to the results of a soil census conducted on the 15,000-acre mature tea plantation in Yinghong Hua Tea House in 1980, 67.4% of the tea plantation soil was found to be deficient in potassium, indicating that most of the tea plantations needed potassium fertilizer to ensure high yield
