摘要:
采用室内恒温(25℃)培养的方法，研究施用不同用量的柳枝稷茎、叶对土壤有机碳(SOC)和微生物量碳(MBC)的影响，柳枝稷茎、叶在土壤中分解特性。结果表明：柳枝稷茎、叶施入土壤培养90 d后，随着柳枝稷茎、叶施入量的增加，SOC和MBC含量明显增加。在柳枝稷茎、叶施用量相同的条件下，施入柳枝稷叶后，土壤微生物量碳的含量高于施用茎的含量，而施用叶的土壤中有机碳的含量低于施入茎的土壤有机碳的含量。柳枝稷茎、叶在土壤中的分解率具有一定的差异，且与施用量有关。在相同的柳枝稷茎、叶施用量条件下，叶在土壤中的分解率高于茎的分解率，表明了茎中的有机碳在土壤中周转期比叶中的长，说明施用柳枝稷的茎可以有效地促进土壤有机碳的累积。
Abstract:
An incubation experiment under the constant temperature of 25℃ was conducted to investigate the effect of amendment of leaf and stem of switchgrass(Panicum virgatum) on soil organic carbon(SOC) and microbial biomass carbon(MBC) and the decomposition characteristic of the leaf and stem at various amendment rates of switchgrass leaf and stem. The results showed that the contents of SOC and MBC increased with amendment rates of switchgrass leaf and stem after the incubation of 90 days. Under the same amendment rates of leaf and stem, the pools of soil MBC were larger in the treatments of leaf amendment than that in the treatments of stem amendment, whereas the contents of SOC were higher in the treatments of stem amendments than those in the treatments of leaf amendments. There was a certain discrepancy of decomposition rate between the leaf and stem. The decomposition rates of leaf and stem were determined by the amendment rates. Under the same amendment rates of leaf and stem, the decomposition rates of leaf were higher those of stem, indicating that turnover rate of organic of stem in the soil was longer that of the leaf, and the amendment of stem was conductive to accumulation of organic carbon in soil.
