长期施肥对土壤有机碳、氮组分及微生物多样性影响的研究进展

摘要

Organic carbon and organic nitrogen in soil are closely related to soil environment and soil fertility.Through combining domestic and foreign literatures about long-term fertilization experiment, the law of differences in soil organic carbon and nitrogen component under different fertilization models were researched, and the response characteristics of microbial diversity to different fertilization models were also discussed.Moreover, the future studying direction for this field was prospected.%土壤有机碳、氮组分与土壤环境、土壤肥力密切相关.通过综合国内外长期定位施肥试验研究报道,研究不同施肥方式下土壤有机碳、氮组分的差异规律,探讨微生物多样性的响应特征,并对该领域今后研究方向提出展望.
