Abstract To solve the existing problem in straw no-tillage potato（Solanum tuberosum L.）, the comparative study on 3 cultivation patterns were performed. The results showed that all these 3 cultivation patterns were better than the conventional pattern. Among them the straw wrapping and coverage with black film in winter-planting potato could shorten the germination time, increase the commercial potato rate and potato numbers of single plant, improve the potato quality of single plant, remarkably raise the yield and efficiency. The straw wrapping and coverage with black film all precede the straw no-tillage pattern. The net income from straw wrapping pattern can reach 6 042.15 Yuan per hm2 and the ratio between investment and output is 1.76.
