摘　　要：在新疆阿瓦提县进行了正常灌溉和亏缺灌溉条件下保水剂及保水剂与尿素配施在长绒棉新海16号施用效果的田间试验。试验结果表明，随着保水剂使用量的增加棉田0～20锄土壤含水量也有增大的趋势；保水剂对棉花植株的生长发育具有一定促进作用；使用保水剂对棉花都表现出一定的增产效果，在亏缺灌溉时保水剂的增产效果好于正常灌溉；正常灌溉和亏缺灌溉都以施用保水剂60mg／hm^2产生的经济效益较高，但以亏缺灌溉条件下获得效益更高。Field experiments were carried out in Awati County in Xinjiang to study the effect of mulfifunctional water absorbant,nitrogen（N） fertilizer and their interaction on Xinhai 16 long-fibre cotton under water stress and well - watered condition. The result showed that the moisture content in 0 ～ 20 cm soil will be increased when the quantity of water absorbent increases. The application of water absorbent is favorable for Xinhai 16 long-fibre cotton growth and yield under both water stress and well-watered condition. But in the aspect of improving yield , water absorbant was most effective under water stress. By applying water absorbent 60 mg/hm^2, the economic benefit was the highest under both well- watered and water stress conditions, but the economic benefit was still higher under water stress condition.
