摘要
旱作农业是世界各地广泛存在的一种农业生产方式,其土壤碳汇潜力备受关注。探讨旱作农田土壤固碳影响因素、固碳过程、固碳效果等,研究认为施用有机肥、免耕、深耕、秸秆还田等保护性耕作措施能使表层旱地土壤固碳量增多,生物降解薄膜覆盖可促进土壤有机碳固定,合理安排农作物有助于提高土壤固碳能力。
Dry farming is a kind of agricultural production mode widely existed in the world,and its soil carbon sequestration potential has attracted much attention.The paper discussed the influencing factors,carbon sequestration process and effect of soil carbon sequestration in dry farmland.It was concluded that protective tillage measures such as application of organic fertilizer,no-tillage,deep tillage and straw returning could increase the carbon sequestration in surface dryland soil,biodegradable film mulching could promote soil organic carbon sequestration,and rational arrangement of crops could improve soil carbon sequestration capacity.
