摘要
为了探求塔里木灌区农田排水的利用潜力,利用不同灌溉水质对棉花各生育阶段设置不同的灌溉处理,分析了不同灌溉水质对棉花不同生育阶段生长发育及产量的影响。结果表明:与淡水灌溉棉花相比,利用农田排水灌溉对棉花的株数、株高、单株结铃数、单株果枝数、干物质积累及籽棉产量等农艺性状的影响较大;棉花的单位面积株数、株高、单株结铃数均显著减小。但在播前和苗期用淡水灌溉,而在棉花的生长中后期用农田排水灌溉,对棉花农艺性状和产量的影响不大。
The objective of this study was to characterize the spatial distribution of farmland drainage in the Tarim irrigation area of the upper Tarim River and to provide some suggestions on utilizing farmland drainage water for agricultural irrigation and mitigating the crisis of water resources and water eutrophication. Studies have shown that agricultural drainage to the irrigation of cotton plants, plant height, boU number per plant, fruit num- ber per plant, dry matter accumulation and agronomic traits, such as cottonseed production of a greater impact. Irrigation with fresh water compared to cotton, cotton plants per unit area, plant height, boll number per plant are significantly decreased.
