大颗粒尿素是属于采用物理法生产的限制溶解类缓释尿素 ,其粒径为 2～ 12ｍｍ ,与普通尿素相比 ,大颗粒尿素表面光洁圆滑 ,颗粒均匀 ,不易粉碎和吸潮结块 ,适合于长距离运输和存贮。在田间施用时 ,大颗粒尿素肥效持久 ,氮损失率低 ,增产增收效果明显。虽然大颗粒尿素的销售价格
Large-granule urea belongs to the limited-dissolution slow-release urea produced by physical methods, and its particle size is 2-12mm. Compared with common urea, large-particle urea has smooth and smooth surface, uniform particles, and it is not easy to crush and absorb moisture, suitable for agglomeration. Long distance transportation and storage. When applied in the field, large-particle urea has long-lasting fertilizer effect, low nitrogen loss rate, and obvious effect of increasing production and income. Although the sales price of large-particle urea
