涂层缓释一次肥是以涂层大颗粒尿素为基本氮源,同时对磷、钾分别涂层、造粒,采取掺混工艺,而配制生产的作物专用,具有可控缓释特性的肥料。采用涂层技术生产的涂层缓释一次肥与其它形式复(混)肥料相比,具有投资少、成本低、配肥灵活、针对性强等优点。并能根据不同作物,不同土壤和生态环境来确定平衡施肥方案。 Coating slow-release fertilizer is coated with large particles of urea as a basic nitrogen source, while the phosphorus and potassium were coated, granulated, to take the blending process, and the preparation of the production of crops, with controlled release characteristics of the fertilizer . Compared with other forms of complex (mixed) fertilizers, the coated sustained-release primary fertilizer produced by the coating technology has the advantages of less investment, low cost, flexible and targeted fertilizer. And according to different crops, different soil and ecological environment to determine the balanced fertilization program.
