中文摘要	在甘肃陇东旱塬区以田间试验的方式进行了SODm缓释氮肥施用方式对半湿润偏旱区冬小麦性状、水分利用效率及经济效益的影响研究,结果表明:施用SODm后,由于其缓慢的释放效应,氮肥的效应延长,在冬小麦返青后土壤中依然能有充足的养分,可以使作物营养生长获得有利影响. SODm一次性施用可以使冬小麦较常规氮肥和当地传统施肥方式水分利用效率提高0.76kg/mm.hm~2,增产10.48%,产值增加805.88元/hm~2,净产值增加1105.88元/hm~2,提高21.98%,增产幅度明显高于其他处理,表明SODm一次性施入可以提高陇东旱塬冬小麦产量和经济效益.
英文摘要	Field experiment in the east of Gansu was conducted to study the effect of SODm slow release fertilizer in ways on winter wheat in semi-humid region and its economic benefit. The results showed that: After application of SODm slow release nitrogen fertilizer, due to the effect of slow release of nitrogen fertilizer, soil nutrients were sufficient in winter wheat after reviving. And the extended effect of slow release nitrogen fertilizer made the crop vegetative growth beneficial. Single basal application of slow release nitrogen fertilizer could make winter wheat improve water use efficiency compared to traditional nitrogen fertilizer together with the traditional fertilization methods by 0. 76kg/mm-hm~2, yield increase by 10.48%, the output value increase by 805.88yuan/hm~2 and the net output increased to 1105.88yuan/hm~2, an increase of 21.98 percentage. The increase of yield was significantly higher than other treatments indicating that applicationg of SODm slow-release nitrogen fertilizer in Longdong winter wheat growth could obtain better yields and improve economic benefits.
