The invention relates to a method for calculating spray irrigation time under combined spray irrigation on the basis of spray irrigation overlap factors. After a spray irrigation intensity matrix andthe spray irrigation overlap factors are introduced according to a relation between spray irrigation time t' of the spray irrigation overlap factors and predicted spray irrigation quantity W requiredby a unit area, influences of a gap on single-time spray irrigation time are effectively eliminated, and high accuracy in spray irrigation time calculation is achieved by adoption of the spray irrigation overlap factors. In addition, spray irrigation time of crops in areas with different spray irrigation overlap factors is well controlled, a series of problems caused by nonuniformity in spray irrigation intensity are avoided, and water resources are greatly saved. 本发明涉及种基于喷灌重叠因子的组合喷灌下喷灌时间的计算方法，是根据喷灌重叠因子的喷灌时间t′和预测的单位区域所需的喷灌量W的关系引入喷灌强度矩阵和喷灌重叠因子后有效的排除了关于间距对单次喷灌时间影响，且利用喷灌重叠因子对于喷灌时间计算更为精准。不但不同重叠因子区域作物的喷灌时间得到良好的控制，还避免了喷灌强度不均
