养分资源综合管理与肥料创新——探索化肥行业发展之道

通过数据,阐明美国以最廉价的生产方法生产化肥,以养分综合利用、合理的种植结构,尽可能减少化肥用量,从而达到化肥高效利用、农业高产、保护环境的多重目标。我国与美国存在较大差距。介绍了中国农业大学资源与环境学院所进行的“养分资源管理”研究项目,从理论到实践上把传统观念中施肥为增产的单一目标,转变到实现高产、优质、资源高效利用和生态环境保护的多重目标。这是缩小我国与美国在化肥施用上差别的最佳途径之一。

The integrated management of nutrient resources and creativity on fertilizer field-seeking the development way of chemical fertilizer industry

With the simplest technology for chemical fertilizer production of low cost,the integrated application of nutrient resources,the reasonable planting structure and the decreasing amount of applying fertilizer,the multi-aims are achieved in US from highly efficient application of chemical fertilizer,good agricultural yield and environmental protection,however the great difference exists between China and US,based on the analysis on some data.Thus,the project"management of nutrient resources"researched by the College of Resources and Environment,China Agricultural University is described from theory and practice,including the multi-aims of good agricultural yield,excellent product quality,highly efficient application of resources as well as ecological and environmental protection,instead of the single aim of increasing agricultural yield from application of chemical fertilizer in the traditional concept,which is one of the best ways for reducing the difference between China and US.
