The content of methyl functional group of humus is an important index to evaluate the humification of soil.
胡敏酸甲氧基功能团的含量多寡是衡量土壤腐殖质化的重要指标。
Both humification and decomposition are impeded.
腐殖化过程与分解过程均受到抑制。
The plant residue with more lignin has a higher humification coefficient. As the residue containing more N is more favorable to the formation of soil microaggregate.
