A non-tillage intercropping test of potato varieties of Qingshu series was conducted in mulberry garden in winter to seek a fine intercropping pattern and to screen the suitable potato varieties. The results showed that compared with potatoes of conventional non-tillage cultivation, growth traits of the five potato varieties of Qingshu series were better in different growth periods, such as plant height, stem diameter, leaf number, and the yield structure was improved. Potato weight and potato number per plant were increased by 21.14% and 16.32%, respectively. Potato production and the proportion of larger potatoes were raised by 5.92% and 11.94%, respectively. The yield of Qingshu 8 was the highest (37 070.37 kg/hm 2), 8.98% higher than CK. Therefore, mulberry intercropping potatoes was a new cultivation way to be generalized and applied in the production practice. Qingshu 8 was an ideal potato variety for non-tillage intercropping in mulberry garden.
