磷酸铵钾是一种高浓度氮、磷、钾水溶性复合肥料,总有效成份≥70％,肥效高而稳定,尤其适宜于叶面追肥。经江苏省农业科学院和江苏里下河地区农科所等单位在三十多个试验点上进行了肥效试验,取得了不同土质、不同作物(大豆、玉米、水稻等)肥效数据,增产效果与磷酸二氢钾相似。生产工艺可行,可用国内中品位磷矿石作原料,具有原料适应性强,生产中排放物能综合利用,比磷酸二氢钾生产成本低,施用磷酸铵钾是经济而合算的。
Potassium ammonium phosphate is a high concentration of nitrogen, phosphorus and potassium water-soluble compound fertilizer, the total active ingredient ≥ 70%, high efficiency and stability, especially suitable for leaf top dressing. The fertilizer efficiency experiment was carried out at more than thirty test sites by Jiangsu Academy of Agricultural Sciences and Jiangsu Lixiahe Agricultural Science Institute, and the fertilizer efficiency data of different soil types, different crops (soybean, corn, rice, etc.) Potassium dihydrogen phosphate is similar. Production process is feasible, available in the domestic grade phosphate rock as raw material, with strong adaptability of raw materials, production can be comprehensive utilization of emissions than the production of potassium dihydrogen phosphate low cost, the application of ammonium potassium phosphate is economical and cost-effective.
