摘　　要：在池栽条件下研究了春播覆膜(CBFM)、春播露地(CBLD)、夏播覆膜(XBFM)、夏播露地(XBLD)、麦田套种(MT)和麦田套种露地(对照,MTLD)6种花生种植方式的耗水特点和水分利用效率差异。结果表明:不同种植方式下花生的耗水量不同,当生育期的降水量相同时,耗水量与土壤贮水消耗量呈正比,降水耗水量与土壤贮水消耗量占农田耗水量百分率呈反比。春播覆膜处理的荚果产量、水分利用效率、降水利用效率、土壤贮水利用效率均最高,麦田套种最低;夏播覆膜与夏播露地相比,降水利用效率高;麦田套种露地与麦田套种相比,土壤贮水利用效率高。In the pond culture conditions, the water consumption characteristics and water use efficiency of peanut were studied under the planting patterns of spring sowing with film （CBFM） , spring sowing in open field （CBLD） , summer sowing with film （XBFM） , summer sowing in open field （XBLD） , intercropping with wheat （MT） and sowing in wheat field （MTLD ,as the control）. The results showed that the water consump- tion of peanut was different under different planting patterns, when the amount of precipitation was the same in the growth period. The water consumption was in proportion to the soil water consumption, but the percentage of precipitation water consumption accounted for farmland water consumption was inversely proportional to that of soil water consumption accounted for farmland water consumption. The pod yield, water use efficiency, pre- cipitation use efficiency and soil water use efficiency were the highest under the treatment of CBFM, while that was the lowest under MT. The precipitation use efficiency under XBFM was higher than that under XBLD. The soil water use efficiency was lower under MT compared to that under MTLD.
