The aim was to investigate the effects of foliar spraying KNOa and Ca（NO3）2 combination on yield of potato. It was discovered that using 397 g/666.7 m2 Ca（NO3）2 or 382 g/666.7 m2 KNO3 every time in total of four had obvious effects yield of potato, was 1 096.3 kg/666.7 m2 and 1 210.5 kg/666.7 m2. The optimal combination was 310 g/666.7 m2 Ca（NO3）2 and 239 g/666.7 m2 KNO3 ,the yield of potato was 1 273 kg/666.7 m2.
