保水缓/控释肥料是低碳经济时代的新型增值肥料,是未来肥料产业最具前景的重要方向之一。综述了近年来我国保水缓/控释肥料的研发进展和保水剂与肥料复合一体化技术的4种制备方法,分析了相关研发存在的问题,提出了我国保水缓/控释肥料开发应进一步采取的对策。 Slow release water / controlled release fertilizer is a new value-added fertilizer in the era of low-carbon economy and is one of the most promising future directions for the fertilizer industry in the future. In this paper, four kinds of preparation methods for the research and development of slow / controlled release fertilizers and the integrated technology of SAP and fertilizer were reviewed. The problems in the research and development were analyzed. It was suggested that the development of slow / controlled release fertilizers should be further taken Countermeasures.
