钾是作物生长三要素之一。施用氯化钾,在缺钾地区可使作物大幅度增产。但因氯化钾含有氯离子,会使甜菜含糖量降低,洋芋淀粉减少,烟味不香,葡萄品质变劣。所以,这些作物都不宜施用氯化钾。据土壤普查,我省大多数地区土壤含钾丰富,一般不需施钾肥,对氯化钾更须慎 Potassium is one of the three elements of crop growth. The use of potassium chloride, potassium-deficient areas in the crop can be significantly increased. However, due to chloride chloride containing chloride, will reduce the sugar content of sugar beet, potato starch reduced, smoke is not fragrant, poor quality of grapes. Therefore, these crops should not be used potassium chloride. According to the soil census, the soil in most parts of our province is rich in potassium, and generally does not need to be applied with potassium fertilizer.
