- Nitrogen (N) fertilizer use efficiency can be improved by two ways, that is, optimized N fertilizer management and genetic improvement of nitrogen use efficiency (NUE) of crops. 摘要提高氮肥利用率依赖于氮肥优化管理及作物氮素营养效率的遗传改良。
- N fertilizer use efficiency N肥利用率
- It is very important to increase fertilizer use efficiency (FUE) in China for its relatively low FUE and serious losses of nutrient. 尽管耕地面积只占世界耕地面积总量的7%25，但中国的化肥施用量却接近世界总量的1/3。
- The low fertilizer use efficiency (FUE) and the pollution of the environment for lost nutrient has been one of the main obstacle factors of society,enconmy and agricultural sustainable development. 化肥利用率低以及化肥施用后损失的养分造成的环境污染，已成为全球社会、经济和农业可持续发展的主要障碍之一。
- nitrogen fertilizer use efficiency 氮肥利用率
- increasing fertilizer use efficiency 提高肥料利用率
- Effects of Different Ratios of Base N to Dress N Fertilizer on Nitrate Content in Chinese Cabbage and the N Use Efficiency 氮肥不同基肥、追肥比例对小白菜硝酸盐含量及氮肥利用率的影响
- Take a long view, the amount of N absorption from two root zones of A almost equalized, and the use and residue and also lose efficiency of N fertilizer applied to two zones was close to each other. 总体来看，两个根区的氮素吸收基本相同，其氮肥的利用率、损失率和残留率相近。

- Compared with homotypic lines, CMS lines maintained higher individual nitrogen utilization efficiency than their homotypic lines, but the response to N fertilizer was relatively lower. CMS玉米单株氮效率较高，氮响应度相对较低。
- Fertilizer use efficiency 肥料利用率
- The photoperiod characteristics played an important role in response to N fertilizer. 非光敏品种对高施氮量反应好，其最高产量需要更多的氮。
- Dressing N fertilizer in flowering stage led to the decrease of glutelin content. 开花期追氮导致谷蛋白含量降低；
- Applying N fertilizer during the R4 and R5 periods could increase the crop N-accumulation and yield significantly. 在 R4和 R5 期补充氮肥的供给明显增加植株对氮的积累，并能显著提高大豆产量。
