| 摘 要： | 采用土培试验对玉米植株残体施人后土壤理化性质及有机质组成的变化进行了分析。结果表明，土壤加入玉米植株残体后，土壤微生物生物量碳和氮含量提高，土壤的阳离子交换量增强，松结合态、联结合态和紧结合态腐殖质的含量增加，稳结合态腐殖质的相对含量下降，土壤中五碳糖和六碳糖的含量升高，土壤胶体活性变强。玉米秸秆和根茬对土壤的培肥作用存在差异。

| Abstract: | Mechanism of corn plant residue(CPR) improving soil was studied through a soil culture experiment.After (CPRs) were applied into soil,contents of biomass C and N were augmented,cation exchange capacity of the soil,five-carbon(sugar) and six-carbon sugar were increased significantly,content of loosely combined humic substances,unitedly combined humic substances and tightly combined humic substances also were enriched.However,content of stably combined humic substances was reduced,and five-C sugar was apt to change.CPRs improved activity of soil colloid.Corn stalk is different from corn stubble in effect on improving the soil. |
