| 摘 要： | 研究膜下非充分灌溉条件下施用氮肥对棉花生长发育的调节效应,揭示不同灌溉量下施用氮肥对棉花产量构成因子的效应,为干旱区发展节水高产高效农业提供依据。在南疆生态条件下,选用新陆中54为试验材料,研究灌溉量及氮肥对棉花的农艺性状及产量形成的影响。与灌溉量为3 800 m~3·hm~(-2)处理相比,2 800m~3·hm~(-2)生育进程提前,现蕾增加率、成铃增加率及产量增加率均最高;与不同施氮水平(4个施氮水平0、150、300、450 kg·hm~(-2),分别用N0、N1、N2、N3表示)相比,总体趋势表现为N2N3N1N0。灌溉量及氮肥对棉花干物质形成及其分配有显著的调节效应,灌溉量为2 800 m~3·hm~(-2)处理相比灌溉量为3 800 m~3·hm~(-2)的处理,更有利提高棉花增产率。结合灌溉棉田灌溉量可控的特点,制定相应的灌溉施肥制度,对实现棉田节水高产高效有重大意义。
