Abstract:
     The present invention is related to a production process of complex dispensed liquid fertilizer which is suitable to the actual situation of China, adopts the foliage spray for crops and increases the crop yield. The said process makes the differently proportional urea, ammonium nitrate and additive water to carry out the additive reaction, and then a certain amount of trace element and humic acid are added in, and further the above-mentioned solution is mixed with a supersaturated solution which is compounded with diammonium phosphate, potassium sulfate or potassium chloride and a compounded additive to form a suspension solution. This suspension solution, after having been homogenized and emulsified, is made into the special high-performance liquid complex fertilizer. The investment of this process is less, its cost is low and it is suitable for industrialization.
