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。
The new technology of one-step production of new type of urea-based compound fertilizer using urea, phosphate rock sulfate, calcium magnesium phosphate and potassium salt as raw materials through a series of laboratory experiments and small-scale continuous experiments was introduced. The technology has short process, less equipment, small footprint, energy saving and pollution-resistant features such as fluoride; product is rich in trace elements, fertilizer efficiency significantly increased yield outstanding effect, it is worth promoting the application.
