　　以‘荷兰15’为试验品种，采用随机区组设计进行田间试验，研究不同钾肥品种（氯化钾和硫酸钾）及其用量对马铃薯产量和品质的影响，以期指导马铃薯钾肥的施用。结果表明，不同钾肥品种均提高了马铃薯的产量，降低了还原糖含量。与施用硫酸钾相比，施用氯化钾后，单薯重提高，产量增加幅度较大。若施用氯化钾，用量以18 kg/667m2（K2O）为佳；若施用硫酸钾，用量以21 kg/667m2（K2O）为佳。以优质为目的，钾肥用量低时，氯化钾为优，钾肥用量高时，硫酸钾为优。

A field experiment in Randomized Complete Block Design was conducted to study the effects of different sources (potassium chloride and potassium sulfate) and rates of potassium fertilizer on potato yield and quality in order to guide the application of potassium fertilizer on potato, using 'Helan 15' as experimental material. The results indicated that potato yield was improved, and reducing sugar content was reduced by using different sources of potassium fertilizer. Tuber weight and yield were increased more by potassium chloride than potassium sulfate. 18 kg/667m2 (K2O) was the best when the potassium chloride was used, while 21 kg/667m2 (K2O) was the best when the potassium sulfate was used. In order to get high quality of potato, potassium chloride was superior to potassium sulfate when low rate of potassium fertilizer was used; however, potassium sulfate was superior to potassium chloride when high rate of potassium fertilizer was applied.
