不同农田管理措施下土壤有机碳及其组分研究进展

Research Advances in Soil Organic Carbon and Its Fractions under Different Farmland Management Method

概述了农田生态系统下土壤有机碳的分组方法,包括物理、化学和生物分组,并分别从施肥、耕作、覆盖、秸秆还田、降水和灌溉以及轮作等农田管理措施方面探讨了不同管理措施对土壤有机碳及其组分的影响。

The fractionation methods of soil organic carbon,including physical,chemical and biology ＂separation under farmland ecosystem were reviewed. Then the effects of different farmland management methods on soil organic carbon and its fractions were discussed from aspects of fertil- izing pattern,tillage, mulching, straw turnover, rainfall,irrigation and rotation.
