摘要
在实验室条件和野外条件下，测定了泥炭植物残体分解过程中有机碳、氮和有机质的碱提取物含量及其光密度的变化，分析了年生物周期内各种成炭植物的腐殖化速率．９个月的腐殖化实验结果表明，有机碳和氮的含量相对提高，碳氮比减小；在野外条件下，成炭植物的腐殖化强度高于在实验室条件下；在年生物期内，除泥炭藓变化不明显外，芦苇、棉花莎草、赤杨和落叶松等都有腐殖质初级产物的生成．
Based on the changes in content of organic Carbon,Nitrogen,alkline extractions and the light density of peat forming plant residues in the decomposition process. Under the lab and field condition respectively,the humification rate of various peatforming plants during annual biological cycle are discussed. The 9-month humification experiment shows that the organic carbon and nitrogen increase relatively, and C/N decrease; the humification intensity of peatforming under field condition is higher than that in lab; during annual biological cycle.Except for that sphagnum have no obvious change, reed cottongrass, alder and larch have formed the initial product of humic substance.
