摘要: 尿素缓释肥是提高氮肥利用率的一种新型肥料,是提升氮营养素利用率和提高农作物产量的重要途径。本文综述了近几年来尿素缓释肥在我国粮食作物小麦、玉米、水稻和经济作物棉花、大豆等作物种植过程中的应用研究现状,认为尿素缓释肥配施应用于农作物种植过程中具有明显的减氮增收作用。同时指出尿素缓释肥在农作物应用中存在的一些问题,例如关于尿素缓释肥对作物品质的影响、缓释材料对环境的影响、缓释曲线与作物营养需求曲线的匹配等相关问题仍缺乏研究。本研究将为今后关于尿素缓释肥的应用研究和广泛推广提供理论参考。

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
