- fertilizer N recovery 氮肥利用率
- Farmers using fertilizer N on legume crops will probably reduce their potential income. 农民向豆类作物施氮肥意味着他们潜在收益的减少。
- The highest ratio of the fertilizer N to total N in plant was found in rosette stage, and then it declined slowly. 同时,施氮量越多,各个时期各部位和整株中肥料氮的比例越大,且均在团棵期达到最大值;
- Fertilizer N not taken up by plant roots is subject to microbial immobilization and losses by denitrification, volatilization and leaching. 未被植物根系吸收的肥料氮会被生物固定和通过反硝化、挥发和淋失而损失。

- On average, the N import from precipitation in 2004-2006 accounted for 28.3% of the applied fertilizer N, suggesting that the N input from precipitation had greater effects on agroecosystem. 2004-2006年随降雨输入农田生态系统的氮平均占可利用肥料氮的28.;3%25,对农田生态系统有着重要影响。
