草莓在整个生育期中对钾的需求量仅次于氮。生产中使用的钾肥主要有氯化钾（ＫＣｌ）和硫酸钾（Ｋ２ＳＯ４）。氯化钾含氯离子较多，施用过量会抑制植物的发育，但氯又是植物必需的元素。为了既可足量补充钾，又能合理供给氯元素，使草莓产量和品质达到最佳，笔者进行了硫酸钾 Demand for potassium is second only to nitrogen throughout the growing season. Potash used in the production of potassium chloride (KCl) and potassium sulfate (K2SO4). Chloride contains more chloride ions, excessive application will inhibit the development of plants, but chlorine is an essential element of plants. In order to supplement enough potassium, but also a reasonable supply of chlorine, strawberry production and quality to achieve the best, I conducted a potassium sulfate
