Analysis of Soil Moisture, Temperature, and Salinity in Cotton Field under Non-Mulched Drip Irrigation in South Xinjiang

The mulch film residues in cotton fields south Xinjiang have caused serious harm to the soil environment and ecological security oasis areas. Non-mulched planting provides an alternative approach this problem. In experiment, irrigation was provided on basis of reference crop evapotranspiration (ET0). Two layouts drip tapes (1T4R—one tape for four rows; 2T4R—two rows) were applied non-mulched, drip-irrigated Xinjiang, their impacts water–heat–salt dynamic changes water consumption yield compared analyzed. experiment shows that 2T4R layout excellent water–salt growth formation. Soil temperature decreased by 0.8 °C belt input increased CNY1200·hm−2. However, a higher profit derived from could compensate expenditure. results show cultivation using non-mulched instead mulched can potentially alleviate environmental problems plastic Although reduced about 15%, nitrogen strategies other field management be adjusted disadvantages.
