超高浓度硝基水溶肥工艺实验研究

Experimental Research on Process for Nitro Water Soluable Fertilizer with Super high Concentration

介绍了水溶性复肥因其速溶速效、节水省工、高效环保的优点,进行了采用硝酸钙与硫酸钾反应制取硝酸钾,加入磷酸用氨中和,再补充适量硝酸铵后制得均一养分的高深度水溶肥的实验。实验结果表明:该工艺小试条件下技术可行,生产出的19-18-19超高浓度硝基水溶性复合肥符合HG/T 4365-2012新标准。

Author has introducd the advantages of water soluable compound fertilizer with its rapid dissolution /effectiveness, water saving ＆amp; time saving, high efficient environment protection , has made the experiment using the reaction of calcium nitrate with potassium sulphate to produce potasium nitrate,adding phosphoric acid and neutralizing by water, after then supplementing moderate ammonium nitrate to produce the water soluable fertilizer with high concentration of uniform nutrient.Experimental result indicates that the process is technically feasible in a small scale test , nitro water soluable com-pound fertilizer produced with 19-18-19 superhigh concentration meets new standard requirement of HG/T 4365-2012.
