英文摘要	Pre-planting soil moisture plays an important role in regulating plant emergence rate and yield, yet there is a paucity of studies on the response of cotton growth and yield to pre-planting soil moisture in arid regions. In this study, the CROPGRO-Cotton model was used to simulate cotton growth and yield in a mulched drip irrigation system, with the interaction of different pre-planting soil water contents and irrigation levels during the cotton growing season. This was undertaken to determine the optimal pre-planting soil water contents and irrigation levels that would produce the highest cotton yield and biomass values in the model simulations. Experimental data of cotton phenology, and the biomass and yield at the maturing stage in 2017 and 2018 was used to calibrate and verify the DSSAT-CROPGRO-Cotton model outputs. Based on the calibrated CROPGRO-Cotton model, scenario simulation was performed using three irrigation levels (24 mm, 30 mm, 36 mm) and eight pre-planting soil water contents [1.2 theta(FC), 1.1 theta(FC), theta(FC) (field water holding capacity), 0.9 theta(FC), 0.8 theta(FC), 0.7 theta(FC,) 0.6 theta(FC), and 0.5 theta(FC)]. The results showed that the simulated cotton phenology and seed cotton yield produced by the calibrated CROPGRO-Cotton model showed good fits with the observed values, thus, satisfying the accuracy requirement for large-scale, mulched, drip irrigated cotton field simulations. However, large deviations were observed between simulated and observed biomass values. According to the simulations, the maximum seed cotton yield and biomass can be obtained from a pre-planting soil water content of 0.8 theta(FC) - theta(FC), and the maintenance of irrigation levels at 30-36 mm during the cotton growing season. These simulation results may serve as reference data for cotton crop production and irrigation management in the Tarim Basin.
