    摘要:

    化肥作为现代农业生产基础物质之一,对保障粮食生产安全和农业高效高产具有重要作用,但因其长期盲目过量施用所引发的系列农产品安全、环境污染及资源浪费等问题日益突显,如何有效权衡粮食产量品质及生态安全与化肥减施增效间关系成为需要解决的系统工程问题。根据对科学施肥技术迫切需求,综合评价了中国化肥施用现状与形势,重点阐述分析了国内外测土配方施肥、缓控释肥施用、精准变量施肥、灌溉施肥及部分大宗农作物典型施肥等现代施肥技术的研究进展、技术特点、应用概况及存在问题等。在此基础上,结合可持续农业发展需求分析了我国化肥施用的发展趁势,提出未来主要发展建议,为构建符合中国国情的化肥减施增效科学管理技术体系及相关研究提供参考。

    Abstract:

    Chemical fertilizer is one of the basic materials in modern agricultural production. It has important significance to the development of grain production safety and high-efficiency agriculture. The problems of agricultural safety production, environmental pollution and cost wastage are increasingly prominent which were caused by long-term blindly excessive application of chemical fertilizers in China. How to effectively balance the relation among grain production, ecological security and chemical fertilizer reduction has become a system engineering problem that must be faced. Considering the requirements for application of scientific fertilization technology, the present situation of chemical fertilizer application in China was illustrated and evaluated. The research progresses, technical features, application statuses and existing problems of modern fertilization technologies were analyzed, such as soil testing and formulated fertilization, slow/controlled release fertilization, precision variable-rate fertilization, irrigation and fertilization, and fertilization for staple crop. Finally, the trends of government policy, technology research and promotion training were expected clearly based on the requirement of sustainable agricultural development, which provided ideas for constructing a scientific fertilization technology and management system with the Chinese national condition and references for related research.
