摘　　要：为了明确井渠结合灌区适宜的井渠灌水配比和灌水定额,以小麦品种豫麦57为材料,探索人民胜利渠灌区不同井渠灌水配比和不同灌水定额对土壤盐分、冬小麦分蘖数、株高、干物质量及产量的影响。结果表明,纯井水灌溉模式下土壤含盐量明显大于纯渠水灌溉模式;井渠灌水配比是冬小麦干物质量累积的重要影响因素;灌水定额为900m3/hm2时,渠井用水比例为33%的灌水模式比较适宜。In order to definite the appropriate irrigation quota and water percentage of well-canal irrigation quota, with the wheat varieties yumai57 as the materials, the effects of irrigation quota and proportion of well-canal water on tiller number, dry matter amount, plant height, yield and soil salinity in the people＇s Shengliqu irrigation area were studied. The results showed that soil salt content under pure well water irri- gation was bigger than that under canal water irrigation. Irrigation water quota and proportion of well-canal water were the important factors affecting dry matter accumulation of winter wheat. Irrigation water quota of 900 m3/hm2 and the canal-well water proportion of 33% were recommended.
