The invention relates to a coated granular compound fertilizer using urea as coating material, consisting of an internal core and one or more layers of films. A high concentration urea slurry is adopted as the coating material, the concentration of coating urea slurry is 30 to 99 percent, and the products consist of internal cores with diameters ranging from Phi 1.0mm to Phi 3.9mm and one or more layers of shells with thickness ranging from Phi 0.1mm to Phi 1.5mm; different layers of the shell are in different colors, and the grain diameters of finish products ranges from Phi 1.8mm to Phi 4.75mm. The invention adopts urea material as the coating material to coat the products, thus realizing instant dissolution effect of the products and solving the problem of the difference between internal core concentration and external core concentration in a same particle, and the comprehensive nutrients can exist in the products at the same time, so the invention can provide a compound fertilizer with more comprehensive and more suitable nutrients proportion for the soil. Since the internal cores or the internal layers have various colors, internal cores with different colors from the products can be seen through the external coating layer with good transparency, and different colors can be adopted for different products to distinguish the application scope, which is more beautiful and has better selling point.
