While relay-planted with middle maturity, the yearly nitrogen absorption quantity of summer-sown late maturity maize YD13 was highest, those of summer-sown early maturity maize were middle, and those of summer-sown middle maturity maize were lowest.

不同熟期春夏玉米套作氮素竞争利用及其对产量和品质的影响 2.1 套作体系氮素竞争利用差异研究结果表明，与相同晚熟、早熟春玉米套作的夏晚熟品种YD13套作模式全年吸氮量均较高，其次是中熟品种，早熟品种全年吸氮量最低；而与中熟春玉米品种套作时，仍以夏晚熟品种YD13套作模式全年吸氮量最高，其次是早熟品种，中熟品种套作模式全年吸氮量最低。

The result indicates that with organic fertilizer and inorganic nitrogen fertilizer can obviously increase the leaf dimension coefficient, enhance the content of chlorophyll and soluble protein, improve the SOD activity of flag leaf, depress the content of MDA, postpone the speed of decrepitude of flag leaf,; The status with high content of chlorophyll and leaf dimension coefficient lasts longer with organic fertilizer than with inorganic nitrogen fertilizer and the flag leaf have longer functioning time; the combination of inorganic nitrogen fertilizer and organic fertilizer can substantially postpone the speed of decrepitude of winter wheat.

在国内持续时间最长的肥料长期定位（28年）试验条件下，研究了肥料持续施用下冬小麦花后叶面积系数等生理指标的变化，结果表明施用有机肥、氮肥，可明显增大小麦的叶面积系数，增加叶绿素含量和可溶性蛋白含量，提高旗叶的SOD活性，降低丙二醛的含量，延缓旗叶的衰老；施用有机肥较施用氮肥，叶绿素含量及叶面积系数持续高值时间长，旗叶有更长的功能期；长期氮肥与有机肥配施能显著延缓小麦衰老。
