摘要
微生物残体的续埋效应在农田生态系统中对土壤有机碳(SOC)的贡献超过了50%。合理的耕作方式能通过影响土壤微生物群落与团聚体,促进微生物残体在土壤中的积累。因此,研究微生物残体的作用机制,对分析长期高效的农田耕作措施对SOC的固持作用至关重要。本文综述微生物残体对SOC的贡献途径与大小、耕作方式对SOC和微生物残体的影响、耕作方式影响微生物残体的原因,分析耕作方式影响微生物残体调控SOC含量的作用机制,为农田固碳提供依据。
Microbes remaining in soil after farming contribute over 50%of soil organic carbon(SOC)in the agri-ecosystem.Appropriate tillages benefit the diversity and accumulation of microorganisms as well as the aggregation and properties of soil on farmland.Thus,understanding the ecological process is essential to achieve a long-term,efficient agriculture operation with maximized SOC retention.This article reviews the research progress at home and abroad encompassing the subjects such as,the pathways and contribution to SOC by microbial residues,the direct and indirect impacts of tillage methods on SOC,and the relations between tillage and microbial community in soil.
