尿基氮磷钾复合肥新工艺的研究

Research on a New Technology for Ureido - nitrogenous- phosphatic - potassium Compounded Fertilizer

介绍了本所通过一系列实验室试验和小型连续试验开发成功的以尿素、磷矿硫酸、钙镁磷肥、钾盐等为原料一步法生产新型尿基复合肥的新技术。该技术具有流程短、设备少、占地面积小,节能降耗及解决氟污染等特点;产品富含中、微量元素,肥效显著提高,增产效果突出,值得推广应用。

Through a series of laboratory and small scale continuous experiments with urea, phosphorous ore sul-furic acid, calcium- magnesium- phosphatic fertilizer, potassium salt, etc. as raw materials, a single - step new technology for producing the title fertilizer has been developed by the authors.The process is short, the equipment is less,the layout area is small, the energy consumption is low, and there is no fluoro- pollution.The product also contains proper amount of medium and micro quantity elements, which effectively improves the fertilizer s results , and thus greatly promotes the harvest. The process so developed is worth popularizing.
