记者在近日由中国氮肥工业协会于安徽阜阳主办的2025年中国氮肥、甲醇技术大会上了解到，目前大颗 粒尿素产品正迎来广阔的市场前景。 统计数据显示，2024年国内大颗粒尿素产量达1177.86万吨，较2023年增加76.11万吨。其中，一次造粒 大颗粒尿素产量为1046.67万吨，比2023年减少5.66万吨；二次造粒大颗粒尿素产量为131.19万吨，较 2023年增加81.77万吨。从产品产量变化来看，2024年国内大颗粒尿素总产量较上年增加显著，主要得 益于二次造粒大颗粒尿素明显增产。 "预计2025年尿素市场规模将达1400万吨，年复合增长率约为5.5%，将继续保持稳定增长。"山东晋控明 水化工集团有限公司副总经理任延东表示。 据任延东介绍，近年来大颗粒尿素之所以受到重视，皆因其三大特性：一是颗粒硬度高，不易吸潮结 块，适合长距离运输和远洋出口及长期储存。二是颗粒大、溶解慢，能减少氮流失从而延长肥效，有效 减轻土壤酸化。三是粉尘含量极低、流动性好，在工业用途上可作为烟气脱硝剂等。 从大颗粒尿素需求结构来看，大致涉及三方面。首先是用做农业基肥。近年来大颗粒尿素在尿素产品中 占比逐年上升，已占到农业基肥用肥的6 ...
