摘要
为了探讨农业可持续发展中的养分管理问题,简要介绍了国际植物营养研究所(IPNI)近年来创新的"4R"养分管理概念及其科学原理,并从经济、社会和环境层面讨论了影响"4R"养分管理的主要因素及其对农业可持续发展的影响,提出了通过对各管理层面的完善和效果反馈逐步发展形成区域内的最佳管理系统的途径,为实现现代农业生产的可持续发展从改善作物养分管理的角度指出了方向。
To investigate and discuss the issues of nutrient management in sustainable agricultural production,this paper briefly introduced the concept and scientific principles of‘4R'nutrient stewardship which was innovated by the International Plant Nutrition Institute(IPNI)in recent years.The authors discussed the main factors that affecting 4R nutrient stewardship and sustainable agricultural development in economic,social and environmental fields.This paper also suggested that a best nutrient management practice should be established step by step through the improvement of nutrient management levels and result feedback system.It indicated the direction of how to realize the sustainable development of modern agriculture through better crop nutrient management.
