中文摘要	[目的]探讨保水剂和促根粉对棉花生长发育的影响,为其在棉花生产中的应用提供参考.[方法]采用人工气候室-棉花盆栽试验,研究了两种水分状况下(水分充足与渐进干旱),保水剂和促根粉对棉花地上部干物质积累、养分吸收与水分消耗利用的影响.[结果]两种水分状况下,与对照相比,施用保水剂可使棉花地上部生物量增加5%～39%,养分吸收与利用显著增加,水分利用率提高3%～31%,且以保水剂A1优于A2;保水剂的应用虽显著提高了水分利用率,但对耗水量没有明显影响,可能与使用方法与使用量有关.促根粉对棉花地上部生物量及养分和水分的吸收利用作用不明显,但其与水分的交互作用对N的吸收利用具有明显影响.[结论]保水剂在棉花生产中有一定的应用价值.
英文摘要	[Objective] The study was to provide a reference with the application of SAP and promoter in cotton production. [Method] A pot experiment under two different water conditions (sufficient water condition and evolution drought) was made in artificial-climate-chamber to define the effects of SAP and the root promoter on cotton in arid zone, and the differences of cotton upside biomass, nutrients and water absorption and utilization were analysed. [Result] The results showed that under two different water con-ditions, cotton biomass increased by 5% to 39% with SAP,nitrogen and phosphrous and potassium absorp-tion and efficiency increased significantly,and water use efficiency increased by 3% to 31%; SAP Al was better than A2;there was no obvious impact on the water consumption using SAP in this study, which may be correlated with the methods and amount of SAP used. The effects of the root promoter on cotton upside biomass,nutrients and water absorption and utilization were not strong,except that its interaction with the moisture was beneficial to nitrogen absorption and utilization. [Conclusion] The SAP is beneficial to cotton production.
