Using potato "Favourite" as material, the effects of growth regulators on the texture characteristics, commodity rate, yield and starch content of potato tubers were studied. The results showed that the two growth regulators had a certain effect on the texture characteristics of potato tubers. They could reduce the tuber hardness and increase the tuber starch content. There was a significant negative correlation between tuber hardness and starch content. The growth regulator "Guoranduo" can significantly increase the commercial potato rate of potato chips, and "Tianda 2116" can increase the potato yield, which is 12% higher than that of conventional cultivation.
