摘　　要：通过大田试验,研究了畦灌和滴灌条件下亏缺灌溉对黄河流域麦后移栽棉生长发育和产量品质的影响。结果表明,水分亏缺抑制了麦后移栽棉株高等营养生长和单株成铃数等生殖发育,降低了产量品质;滴灌条件下麦后移栽棉生长发育和产量品质均优于畦灌;滴灌充分灌溉下籽棉产量最高,轻度亏水灌溉下产量仅降低3.8%,但全生育期耗水量减少了9.0%。在水资源日益紧张的黄河流域棉区,麦后移栽棉以滴灌轻度亏水灌溉为宜。Through field experiments, the effects of deficit irrigation on growth, yield and quality of trans- planted cotton after wheat harvest were studied under border irrigation and drip irrigation in Yellow River basin. The results showed that water deficit inhibited the growth of nutrients （such as plant height） and the reproductive developments （such as the bolls per plant）, and reduced the yield and quality. The growth, yield and quality of transplanted cotton after wheat harvest under drip irrigation were better than those under border irrigation. The seed cotton yield was the highest under sufficient drip irrigation. Com pared with the highest seed cotton yield, the seed cotton yield under drip irrigation with mild water deficit only decreased by 3.8%, but water consumption decreased by 9.0 % in whole growth period. In Yellow River basin, drip irrigation with mild water deficit was recommended for transplanted cotton after wheat harvest .
