在大田进行了一项为期两年的试验，以测量耕作和施氮对覆盖作物栽培玉米氮素利用效率和籽粒产量等各种农艺性状的综合影响。免耕4年后，不施和高施氮肥条件下，氮素利用效率、氮素收获指数、氮素再流动和氮素再流动效率均显著提高。免耕条件下，仅施氮肥籽粒产量和氮含量较高。因此，以连续免耕为基础的农艺措施有望提高玉米氮素利用效率。
A two-year experiment was conducted in the field to measure the combined impact of tilling and N fertilization on various agronomic traits related to nitrogen (N) use efficiency and to grain yield in maize cultivated in the presence of a cover crop. Four years after conversion to no-till, a significant increase in N use efficiency N harvest index, N remobilization and N remobilization efficiency was observed both under no and high N fertilization conditions. Moreover, we observed that grain yield and grain N content were higher under no-till conditions only when N fertilizers were applied. Thus, agronomic practices based on continuous no-till appear to be a promising for increasing N use efficiency in maize.
