In this study, we used five different mulching films and eight treatments, black film(T1), silver film(T2), black single white film(T3), black single white film+weeding(T4), black double white film(T5), black double white film+ weeding(T6), white film(CK1), white film+weeding(CK2) on two varieties potatoes(early maturing variety Zhongshu 5 and medium and early maturing variety Xingjia 2) to learn about the effect of cultivation methods on the potatoes and their weed growth. The results showed that the effects of mulching cultivation on the phenological period of two different maturity varieties were different. Black film mulching prolonged the growth period of medium and early maturing varieties, but had little effect on early maturing varieties. Different mulching cultivation methods had significant effects on the emergence rate, plant height, number of tubers per plant and tuber weight per plant of early maturing variety Zhongshu 5. Black film mulching increased the number of tubers per plant of early maturing variety Zhongshu 5, which was significantly different from CK2, T6 and T4. With the increase of the area of black part of plastic film, the rate of tuber green potato decreased and those of white film, black double white film, black single white film, black film decreased in turn, and the rate of Zhongshu 5 was higher than that of Xingjia 2. The grass control effect of black film was better than that of white film combined with herbicide. The weeding effect of black single white film and black double white film was not as good as that of black film and silver black film. The treatments of white film, black single white film and black double white film could significantly increase the yield, and the yield increase effect of black single white film achieved optimally and its yield was the highest. The yields of Zhongshu 5 and Xingjia 2 T4 were 3150 kg/(667 m2) and 2683 kg/(667 m2) respectively, which increased by 8.9% and 4.5% respectively compared with the CK2 The yield of T6 was 2910 kg /(667 m2), which was significantly higher than that of CK1, T5 and T3. The yield of Xingjia 2 T1 was 2583 kg/(667 m2), which was significantly higher than that of T3. The yield increase effect of black film and silver black film achieved optimally with no herbicide application.
