茶树增施钾肥已日趋重要。但由于硫酸钾和氯化钾所含的SO_4~-和Cl~-,对茶树生长所产生的影响不同。正如茶园在施用氯化铵后,氯离子对茶树容易产生“氯害”那样,以致把茶树列为“忌氯”作物。因此在茶叶生产上都要求配施硫酸钾而不愿施氯化钾, Tea has increased the importance of potash fertilizer. However, the effects of tea tree growth are different due to SO 4 - and Cl ~ - contained in potassium sulfate and potassium chloride. As the use of ammonium chloride in tea plantations, chloride ions are prone to “damage” to tea trees, resulting in the tea tree as a “bogey” crop. Therefore, the production of tea are required with potassium sulfate rather than applying potassium chloride,
