Abstract: 【 Objective 】The objective of this study is to study the effects of high-strength plastic film on soil temperature, humidity and cotton growth in cotton field. 【 Methods 】In this experiment, two treatments, high-strength plastic film (H) and ordinary plastic film (T), were carried out in the drip irrigation cotton field in Tumshuk City, Xinjiang, and the effects of the two kinds of plastic film mulching on soil temperature, humidity and cotton agronomic and economic traits of cotton field were statistically analyzed, and the residual plastic film after use was recovered and compared. 【 Results 】Compared with ordinary mulch film, the high-strength plastic film warmed the 0-5cm soil by 1.72%-8.7%, and the soil at the 5-10cm layer by 1.24%-3.1%, and the warming and moisture retention effect was better in the early growth stage of cotton. Compared with the ordinary plastic film T treatment, the number of leaves increased by 1.04-1.54, the plant height increased by 1.5-7.2cm, the number of buds increased by 0.96-1.13, the yield of high-strength plastic film increased by 5.5% compared with ordinary plastic film, and the recovery rate of residual plastic film of high-strength plastic film increased by 18.86% compared with ordinary plastic film. 【 Conclusion 】Compared with ordinary plastic film, high-strength plastic film has better warming and moisture preservation effect, and high-strength plastic film treatment is conducive to the growth and development of cotton roots, stems, leaves and other organs, and at the same time improves the yield of seed cotton, and has high recovery efficiency.
