| 为探讨秸秆还田对作物产量和农田氮素平衡的影响，于2006～2007生长季在河南省滑县进行了田间小区定位试验。研究结果表明，与单施纯氮90、180、270和360 kg/hm2相比，秸秆还田配施同量氮肥能够增加作物产量，冬小麦分别增产7.1%、8.4％、11.1％和10.2％，夏玉米籽粒产量分别增产5.8％、9.5％、10.1％和9.0％，其中，秸秆还田配施N 270 kg/hm2的冬小麦-夏玉米产量最高。为保持周年农田氮素平衡，冬小麦-夏玉米秸秆还田配施纯N不要超过360 kg/hm2。麦玉两熟秸秆还田配施纯N以360～540 kg/hm2为宜。 |

| The current experiment was carried out in Hua Country town of He'nan Province to study the effects of integrated straws on crop yield and nitrogen balance in winter wheat & summer maize in the growing season of 2006～2007. The experiment had 10 treatments: Nitrogen rate of N0, N90, N180, N270, and N360(kg/hm2), with and without crop residue incorporation to soil, respectively. Compared with the treatments with nitrogen fertilizer only, straw incorporation plus nitrogen fer
tilizer of N90, N180, N270, and N360(kg/hm2）, respectively, increased winter wheat grain yield by 7.1%，8.4％，9.5％，11.1％，and 10.2％, increased summer maize grain yield by 5.8%，9.5％，10.1％，and 9.0％. The S+N 270 treatment had the largest amount and increasing tatio of grain yield. In order to keep the nitrogen balance during one year, It is suitable to straw incorporation plus purity nitrogen to apply purity nitrogen to winter wheat and summer maize do not surpass 360 kg/hm2, 360～540 kg/hm2. |
