Abstract: In order to clarify the current situation and influencing factors of farmland mulch film residue in Xinjiang, samples were taken from typical areas in the north and south of Xinjiang to test and analyze the mulch film residual situation and its influencing factors of film-mulched crops in different regions. The results showed that among the six types of mulch film-covered crops (cotton, processed tomatoes, melons, corn, vegetables, and sunflowers), cotton had the highest residue of mulch film at 129.34 kg/hm², while vegetables had the lowest residue at 71.85 kg/hm². By region, the residual amount of film in Aksu area (145.76 kg/km²) was the highest, and that in Tacheng area (92.71 kg/km²) was the lowest. During the first 15 years, the residual amount of film in farmland was positively correlated with the years of mulching. During the 15 to 25 years of mulching, the residual amount of film first decreased and then increased. The residual amount of film in the 0-30 cm layer increased with the decrease of the film thickness, while there was no significant difference in the 0-20 cm and 20-30 cm layers. For the entire 0-30 cm soil layer zone in Xinjiang, the amount of residual film in the sandy soil zone (184.55 kg/km²) was 1.36 times (P˃0.05 ) and 1.49 times (P<0.05 ) as much as that in the loamy soil zone (135.63 kg/km²) and clay soil zone (124.25 kg/km²), respectively, and the difference between the loamy soil zone and clay soil zone was not significant. The further the farmland was from the village, the smaller the residual amount of film was. The residual amount of film was related to crop type, region, mulching year, recycling method, mulch thickness, soil texture and distance from village. The mulching year and recycling method were the main factors affecting the residual amount of farmland mulch film.
