摘　　要：通过管栽膜下滴灌试验,研究了不同灌水量和盐基对玉米冠层生长和产量的影响。结果表明,土壤含盐量在0.958%～0.978%之间时,4 275 m3/hm2是西北半干旱地区膜下滴灌玉米生产的适宜灌溉量;处理Y1Q2较其他处理显著促进了玉米冠层生长,提高了玉米产量。In the experiment the effect of different drip irrigation quota and salt base conditions under mulch films to yield and canopy growth of maize was studied. The results showed that the amount of Q2 drip irrigation was optimum for maize production between the salt content of Y1 and Y3 under mulch films; The treatment of Y1Q2 markedly increased canopy growth and improved the maize yield compared with the other treatments.
