Abstract: Urea slow-release fertilizer is a new fertilizer to improve the utilization rate of nitrogen fertilizer, which is important for improving the utilization rate of nitrogen nutrients and crop yield. The application of sustained-release urea in the cultivation of grain crops such as wheat, corn, rice and economic crops such as cotton, soybean and so on in recent years is summarized in this paper. It is believed that the application of urea slow-release fertilizer in the process of crop planting has obvious effect of reducing nitrogen and increasing yield. At the same time, some problems still lacking research of urea sustained-release fertilizer in crop application are pointed out, such as the influence of slow-release urea fertilizer on the quality of crops, the influence of slow-release materials on environment and whether the slow-release curve matches the crop nutrient requirement curve. This study will provide some theoretical references for the future application research or widespread application of urea sustained-release fertilizer.

Key words: sustained release urea, crops, application
