Abstract In the experiment，potato variety‘Zhengshu No.6’was used to compare the effects of four different cultivation models on its growth，yield and quality.The results showed that，for all treatment，the seedling emergence rate and the stem length of ridge cultivation model was the highest and its mature date was the earliest.While the stem diameter，leaf area index，stolon length，yield and biomass of shallow tillage with rice straw covering was the highest.Moreover，the traditional cultivation methods had the highest commercial potato rate.Among different cultivation methods，except the content of protein，all indexes of quality including contents of dry matter，starch，reducing sugar，vitamin C，etc.shallow tillage with rice straw covering were the highest.Therefore，the cultivation method of shallow tillage with rice straw covering was beneficial to improve the yield and quality of potato.
