随着新陈代谢作用的进行，以氨基糖为代表的微生物细胞壁残留物不断在土壤中积累，并进一步参与土壤碳、氮循环。
During the metabolism, the microbial residues represented as amino sugars were accumulated in soil and probably concerned in further carbon and nitrogen cycling.
施用氮肥可明显增加土壤硝态氮残留数量，并影响其剖面分布；
Application of N fertilizer significantly increased the amount of residual nitrate-N, and affected its distribution in the soil profile.
化肥氮残留很少，大部分进入土壤有机无机复合体中，而部分土壤氮被活化。
There was very little fertilizer N residue left, most of which entered the organo-mineral complex, while a part of the soil N was activated.
