脲甲醛作为世界上研究最早、使用量最大的缓释肥料，在国外已经研究成熟，而在中国近几年才开始研究，起步晚，发展较滞后。本研究从脲甲醛肥料的合成工艺、质量评价、在土壤中的转化与应用阐述了脲甲醛肥料合成及应用现状，指出脲甲醛肥料作为中国一个新兴的肥料研究热点，具有较广阔的发展前景，并为我国脲甲醛肥料的发展提供参考意见。

The urea formaldehyde fertilizer was the earliest study and had the largest use of slow-release fertilizer in the world. It has been studied matured in a foreign country, while it has begun to be studied in China in recent years. The study in china started late, and the development of the fertilizer was lagging. In this study, there were synthesis of urea formaldehyde fertilizer, quality evaluation, the transformation and application status in the soil, to elaborate the synthetic and application status of urea formaldehyde fertilizer. The article also pointed out that as an emerging research hotspot in China, urea formaldehyde fertilizer had more broad prospects for development, and provided a reference for the development of urea-formaldehyde fertilizer in China.
