摘　　要：农田覆盖是减少作物棵间无效蒸发损耗的有效措施 ,但秸秆覆盖下灌水易造成壅塞阻水 ,地膜覆盖下灌水不易入渗 ,同时农田覆盖同分期施肥亦有矛盾。通过在河南省古固寨节水试区的探索、研究 ,使得覆盖条件下的灌水、施肥问题得到了较好的解决。Mulching of farmlands is one of the effective measures for decreasing ineffective evaporation loss in the farm crops' planting space. But watering will easily cause water obstructing under mulching farmlands with straw, and water uneasily to infiltrate to farmlands under land membrane. Meanwhile, mulching of farmlands is in contradiction with staged applying fertilizer. Through exploration and researching in Guguzhai water saving test area, the problem of watering and applying fertilizer under condition of mulching farmlands is better solved. [
