【摘要】 生态化学计量学研究能量和多重化学元素(主要是C、N、P)之间的动态平衡,并分析这种平衡对生态系统的影响,现已成为全球研究热点之一。然而关于农田生态化学计量的研究相对较少。综述了在农田土壤生态化学计量、作物生态化学计量、土壤与作物生态化学计量的相关性3个方面的研究进展,以期为农田生态化学计量的相关研究提供参考。更多还原

【Abstract】 Ecological stoichiometry studies the dynamic balance between energy and multiple chemical elements(mainly C,N,P)and analyzes the impact of this balance on ecosystems. Those have been one of global research hotspots. However,there are few study articles on agro-ecological stoichiometry. The research progress in three aspects of farmland soil ecological stoichiometry,crop ecological stoichiometry,and the correlation between soil and crop ecological stoichiometry were reviewed,in order to provide reference for the related research of farmland ecological stoichiometry.更多还原
