摘要:
为探究北疆膜下滴灌棉花水氮耦合效应,优化水氮管理模式,以NH12026号为供试棉种,采用随机化双因素设计,设置4个不同施氮量水平240、280、320、360 kg/hm2和3个依据作物实际蒸发蒸腾量与降雨量差值(W=ETcc-P)确定的不同灌溉量水平0.8、1.0、1.2 W,分析不同水氮调控下棉花产量指标、经济指标、耗水规律及水氮利用效率的响应特征。结果表明:籽棉产量随灌溉施氮量增加呈先增后降的变化趋势,W2N3处理综合表现最优,籽棉产量达7 902.27 kg/hm2,经济效益16 551.7 元/hm2;全生育期耗水量449.93~622.36 mm,其变化特征随灌溉量增加而明显增加,随施氮量增加呈先增后减的变化趋势;水分利用效率WUE与灌溉水利用效率IWUE受水氮调控作用显著,W2N3处理达到最大,分别为1.46 kg/m3和1.82 kg/m3,较最低处理分别提升39.1%和45.6%;氮肥偏生产力NFP与施氮量呈极显著负相关关系(P<0.01),低氮W2N1处理最优,为30.17 kg/kg;最终基于多目标优化确定灌溉量42066~45410 mm、施氮量27306~314 kg/hm2可协同提升籽棉产量、经济效益及水氮利用效率,达到产量-收益-资源综合最优目标,为北疆膜下滴灌棉花水氮管理方案提供理论依据。
