摘　　要：为了探讨沿黄井渠结合典型灌区地表水与地下水适宜用水比例及灌水定额,以农田小区为研究区域,探索了不同渠井用水比例和不同灌水定额对冬小麦分蘖数、干物质量、株高、叶面积、产量及土壤盐分的影响。结果表明,灌水水源为分蘖数和干物质量的关键影响因素。生育期内仅增加1次渠水灌溉,即可显著降低1m土体内盐分储量。灌水定额为90mm时,渠井用水比例为33%-67%的灌水模式比较适宜。In order to discuss suitable irrigation water quota and proportion of surface water and underground water in the typical well-canal irrigation area along yellow river basin, the effects of different irrigation water quotas and proportions of canal-well water on tiller number, amount of dry matter, plant height, leaf area, yield and soil salinity were studied with the farmland plot as study area. The results showed that irrigation water quality was the key factor influencing tiller number and dry matter amount. The soil salinity was reduced significantly in the soil profile from 0 cm to 100 cm when only adding one time canal water irrigation in the whole growth period. The irrigation water quota of 90 mm and the canalwell irrigation proportion of 33 %-67% was the suitable irrigation model.
