含海藻酸水溶肥生产技术

Production Technology of Water Soluble Fertilizer Containing Alginic Acid

对湿法磷酸生产中的粗磷酸进行螯合处理,然后将形成的磷酸一铵溶液与尿素、氯化钾、硫酸镁溶液以及腐殖酸溶液按配方计量后加入混合机中混合搅拌,再进行计量、包装得到含海藻酸提取物的大量元素全水溶性液体肥料,即含海藻酸水溶肥。该水溶肥可应用于喷滴灌等设施农业,实现水肥一体化,同时达到节水、节肥、省工的目的。

The crude phosphoric acid from wet process phosphoric acid production is treated by chelation,then the formed monoammonium phosphate solution is added to mixer according to measurement formula with urea,potassium chloride,magnesium sulfate solution and humic acid solution to mix and blend,finally it is measured and packed up,the macroelement water soluble fertilizer containing alginic acid extract,i.e.,water soluble fertilizer containing alginic acid,is obtained.This water soluble fertilizer can be used by spraying,drip and irrigation in facility agriculture,attaining the aim of water saving,fertilizer saving and labor saving.
