nitrogen immobilization

基本解釋

Whether placement of nitrogen fertilizer below the layer of crop residue will reduce nitrogen immobilization is not clear.
對于把氮肥施在植物殘體覆蓋層以下是否會減少氮的固定，這個問題目前尚不清楚。
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細菌固定化載體，研究下流式固定床生物反應器的適宜脫氮條件；
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 .
土壤氮礦化-固持周轉（MIT）過程與土壤供氮力及氮素損失間存在密切關系。
