【目的】针对西北灌区春小麦生产中氮肥投入过高、水分利用效率低等问题，探讨复种绿肥及减量施氮对春小麦水分利用特征的影响，以期为优化春小麦生产的水资源高效利用提供理论依据。【方法】采用裂区设计，主区设麦后复种绿肥毛叶苕子（W-G）和麦后休闲（W）两种种植模式，副区设传统施氮(N3,180 kg·hm-2)、减施氮肥15%(N2,153 kg·hm-2)和减施氮肥30%(N1,126 kg·hm-2)3个施氮水平，于2020—2021年研究复种绿肥及减氮对春小麦产量、耗水量及水分利用效率的影响。【结果】麦后复种绿肥结合适量减施氮肥可提高春小麦播前土壤贮水量，W-G较W模式春小麦播前土壤贮水量增加11.5%—13.5%，麦后复种绿肥结合氮肥减施15%（W-GN2）与麦后复种绿肥结合减氮30%（W-GN1）较对照麦后休闲结合传统施氮量（W-N3）春小麦播前土壤贮水量分别提高12.1%—20.2%与15.2%—16.6%,W-GN2与W-GN1处理间无显著差异。W-G较W春小麦耗水量降低12.6%—13.7%，复种绿肥模式中以W-GN2降低春小麦耗水量幅度最大，较麦后休闲结合减氮15%（W-N2）、W-N3分别降低21.8%—25.8%、21.3%—26.3%;W-G通过降低春小麦拔节期至灌浆初期的耗水模系数，增大播种前期至拔节期与灌浆初期至成熟期的耗水模系数（两阶段耗水量占全生育期总耗水量的比例为60.5%—64.1%），有效协调春小麦前后生育时期的水分需求特征，增强了春小麦生长发育过程中水分供需同步性。相比W-GN1、W-GN3,W-GN2处理的调控效应更突出。W-G具有增产优势，较W增产13.5%—14.1%;W-GN2较W-N2与W-N3分别增产16.7%—18.4%与13.6%—14.6%。因而，W-G较W模式提高水分利用效率为29.4%—31.0%，麦后复种绿肥模式中，以W-GN2提高水分利用效率的幅度较大，较W-N2、W-N3分别提高44.2%—46.8%、39.1%—43.5%，较W-GN1、W-GN3分别提高36.2%—50.7%、9.1%—17.0%。【结论】麦后复种绿肥结合减施氮肥15%(即施氮153 kg·hm-2)较传统水氮管理提高春小麦产量及水分利用效率，可推荐为西北灌区春小麦水分高效利用的生产模式。

Alkali metal doping or sulfurization are commonly applied in Cu_(2)ZnSnSe_(4) (CZTSe) solar cell to improve the open-circuit voltage (VOC). However, alkali metal sulfide affording both alkali metal and sulfur is seldom to be studied, which restrains the development of kesterite solar cells. In this study, we evaporate Li_(2)S during selenization process and hope to provide both alkali metal and sulfur to CZTSe film. The result indicates that Li shows a gradient distribution near the surface of CZTSe film and the content of S is slight. The film quality is improved and the recombination at grain boundaries is decreased after Li_(2)S treatment. Besides, the bandgap of the absorber gets wider. Under the synergy of sulfur and lithium (mainly from lithium), the work function of the treated absorber gets higher and the conduction band offset (CBO) is in the ideal range. Combined with these contributions, the V_(OC) of the champion device treated by Li_(2)S dramatically increase by 120 mV. This study discloses that alkali metal brings the main effect on the performance of the kesterite solar cell even an alkali metal sulfide is evaporated, which deepens the understanding of sulfurization of CZTSe and also promote the progress of kesterite solar cells.
