The residue of plastic mulching and premature aging due to high soil temperature at late stage of crop growth would be caused by white plastic film mulching at arid area in northern China, so the main object was choosing the optimal green film mulching. The nine treatments were experimented, including the white and black rapid (WO1 and BO1), medium (WO2 and BO2) , low (WO3 and BO3) degradation film and white and black plastic film (WP and BP), no mulching (CK) to study the effects of different film mulchings on the film damaging and maize yield, and explore instant surface temperature, soil temperature for every hour and every day based on infrared imaging and continuous monitoring technique. The result showed that the proportion of film damaging for black degradation film was higher than that of white degradation film, which was 8.4% after 130d mulching. The higher rank of instant surface temperature was in the order of black film, white film and no film, and the average soil temperature in growth stage was 3410℃, 32.34℃ and 29.12℃, respectively （P<0.05). The higher rank of soil temperature for every hour and every day was in the order of white film, black film and no film, and black film mulching could reduce soil temperature by 1.1℃ of 0~15cm soil layer at daily highest temperature time compared with white film mulching. The average soil temperature difference reached 1.13℃ （P＜0.05) between white and black film mulching at the maize early and late growth stages (May and September), however, it was just 0.45℃ at the maize middle growth stages (from June to August). The proportion of film damaging was influenced by film degradation rate, and it would influence the variability of temperature distribution in space and heat preservation effect. Therefore, lower film degradation rate, less film damaging, and the close heat preservation effect between plastic film and low degradation film mulching. The soil temperature difference for WP, WO3 and WO2 treatments compared with WO1 treatment, respectively, was 3.03℃, 2.70℃ and 1.05℃（P＜0.05), and 3.00℃, 2.57℃ and 1.01℃（P＜0.05) for corresponding black film mulch. There was no difference for maize yield between low degradation film and plastic film whether black or white film mulching. However, there was significant difference among different degradation rates film mulching under same color film mulching （P＜0.05). The higher rank of maize yield for different degradation rates film mulching was in the order of low, middle and rapid degradation film mulching. So, the black film mulching with the best heat preservation effect and higher yield could reduce surface soil temperature at late growth stages, and there were close heat preservation and yieldincreasing effect between black low degradation film and plastic film mulching. It was feasible for developing agriculture in arid areas, northern China to replace white plastic film mulching with black low degradation film mulching.
