土壤中碳的排放、固定与气候变化之间的关系是当前环境问题研究的主要内容之一。化肥的施用改变了农业生态系统的生产力,合理施肥可以提高土壤储碳和控碳的能力。介绍了有机肥料、无机肥料、生物肥料的施用对土壤碳的固定、排放以及粮食产量的影响。建议减少无机肥料的生产、开发绿色有机肥料和微生物肥料、提高人们的环保意识,在2060年前实现“碳中和”的目标。
The relationship between carbon emission and sequestration in soil and climate change is one of the main contents of current environmental research. The application of chemical fertilizer has changed the productivity of agroecosystem and rational fertilization can improve the ability of soil carbon storage and control. The effects of organic fertilizer, inorganic fertilizer and biological fertilizer on soil carbon sequestration, emission and grain yield are introduced. It is suggested to reduce the production of inorganic fertilizer, develop green organic fertilizer and microbial fertilizer, improve people′s awareness on environmental protection, and achieve the goal of "carbon neutrality" by 2060.
