【摘要】 棉花试验设计了五个灌水下限处理，每个处理四个重复，试验提供了各种处理的１ｍ 土层储水量动态过程，进行了田间土壤水量平衡，分析了棉花生长期耗水强度与灌水量关系，棉花产量与灌水量关系，棉花产量及棉花水分生长率与全生育期总耗水量关系更多还原

【Abstract】 The irrigation experiments of cotton were conducted for five irrigation standards, each with four duplications. Based on the dynamic process of soil water content of 1m surface soil layer, field soil water balance is carried out. Therefore, the relations of evapotranspiration (ET) of cotton in growing period with irrigation water volume (I), cotton yield (Y) with irrigation water volume, cotton yield with water consumption for all growing period are studied. The results are of great importance in planning and management of the irrigation district.更多还原
