【摘要】 在晋东豫西（寿阳）旱农试区，研究土壤水肥状况及施肥措施对玉米产量和水分利用效率的影响。结果表明，播前土体贮水量影响玉米的产量和生育期耗水量，适宜的土壤水分状况，有益于产量的提高。耕层土进养分越充裕，玉米产量和水分利用效率就越高．相反，则越低，适宜的土壤养分状况，促进玉米水分的吸收及其有效利用。各种肥料的优化施用，培肥土壤实行秋季施肥，是改变该区低产面貌，有效利用降水的重要途径。更多还原

【Abstract】 Effect of soil moisture and fertilizer application measures upon corn yieldand water use efficiency were studied.The results showde that water storage in soilbody before sowing had an effect upon corn yield and water consumption in the stage ofcorn growth and developrnent,and that suitable soil misture regime was helpful to im-prove corn yield.The richer soil nutrients are in the tilth layer.the higher corn yieldsand water use efficiency are,and vice versa.Accordingly,suitable soil nutrients arefavourable for corn to take in soil water and improve water use efficiency. The optimumapplication of fertilizers of various kinds,bettering soil fertility and implemeiition imple-mentation of fertilizer application in the fall are the important ways to make full use ofrainfall water and improve crop yields in this region.更多还原
