| 摘 要： | 为了避免秋季施肥时多次翻耕土壤而损失水分，提高肥水利用率和生产率，对渭北旱塬结合夏闲地翻耕施肥效应（在７月中旬和８月中旬）进行了研究。结果表明，该施肥方式能提高小麦产量、增加土壤ＮＯ３＾－－Ｎ的积累和提高肥水利用率及生产效率，同时也能缓解秋播劳力紧张的矛盾，有利于适时适墒播种。

| Abstract: | In dry plain of Weibei,combining ploughing summer fallow land and fertilization to increase the fertilizer and water efficiency,the super-advanced fertilization was studied. The results showed that the super-advanced fertilization could increase the wheat yield,the NO3--N accumulation in soil and the efficiency of fertilizer and soil water,especially the productivity of canter. Meanwhile it could relax the tight labour during the autumn sowing time. |
