以洛薯八号马铃薯品种为试材，研究了不同钾肥用量对春露地马铃薯产量及品质的影响。试验结果表明，在一定的土壤条件下，钾肥施用量对马铃薯产量有一定的影响，当钾肥施用量超过25 kg/667 m2时，明显降低了马铃薯的单株质量、单薯质量、商品薯率及产量。适量的钾肥可提高马铃薯淀粉、VC 含量，降低还原糖含量。

In this paper, taking Luoshu No.8 as material, we studied the effects of different application amounts of potash fertilizer on the yield and quality of potato in open field cultivation in spring. The results showed that, under certain soil condition, application amount of potash fertilizer had certain influences on potato yield, when the application amount of potash fertilizer exceeded 25 kg/667 m2, the single plant weight, single tuber weight, marketable tuber percentage and yield of potato were significantly reduced. While suitable application amount of potash fertilizer could improve starch and vitamin C contents, furthermore decreased reducing sugar content.
