The development of a crop production strategy through the use model represents crucial method for assurance stable agricultural yield and subsequent enhancement thereof. There are currently no studies evaluating suitability AquaCrop drip irrigation Gossypium barbadense in Southern Xinjiang, which is primary planting region China. In order to investigate performance simulating growth cotton under mulched irrigation, was locally calibrated validated according different thresholds during key period two years. results simulation total soil water (TSW), evapotranspiration (ETc), canopy coverage (CC), aboveground biomass (Bio), seed demonstrated high degree correlation with observed data, root mean square error (RMSE) <11.58%.
