nitrogen immobilization

基本解释

Whether placement of nitrogen fertilizer below the layer of crop residue will reduce nitrogen immobilization is not clear.
对于把氮肥施在植物残体覆盖层以下是否会减少氮的固定，这个问题目前尚不清楚。
Methods Porous ceramics were used as immobilization carrier. Optimum conditions for nitrate-nitrogen removal of downflow fixed-bed bioreactor were studied.
方法采用多孔陶粒作反硝化细菌固定化载体，研究下流式固定床生物反应器的适宜脱氮条件；
The nitrogen mineralization - immobilization turnover(MIT) process in soil is closely connected with the capacity of nitrogen supply to plant and the loss of nitrogen to environment .
土壤氮矿化-固持周转（MIT）过程与土壤供氮力及氮素损失间存在密切关系。
