Embodiment 1
[0031] Mix 0.2kg of water storage material diapers and 0.1kg of potassium polyacrylate in the pretreatment machine and add them into the nozzle hopper, add 99.6kg of urea particles into the disc implanter, and apply the polyacrylate emulsion adhesive under the condition of rotation Spread on the surface of fertilizer granules. After the coating is completed, power on the disc implanter to generate static electricity on the granules. After moving the nozzle close to the fertilizer granules, start the nozzle to make the water-absorbing material fly to the surface of the fertilizer granules at high speed to complete the surface planting of the granule fertilizer. into the water storage material. The 100kg product granule made in this way has the function of chemical fertilizer and the function of water absorption and water retention simultaneously.
Embodiment 2
[0033] Mix 0.2 kg of water storage material diapers in the pretreatment machine and add them to the nozzle hopper, add 99.2 kg of diammonium phosphate and 0.5 kg of magnesium sulfate particles into the disc implanter, and put polyethylene-vinyl acetate (EVA) adhesive is coated on the surface of the fertilizer granules. After the coating is completed, the implanter is powered on to generate static electricity on the granules. After the nozzle is moved close to the fertilizer granules, the nozzle is turned on to make the water-absorbing material fly to the surface of the fertilizer granules at high speed, and the granules are completed. Water storage materials are implanted on the surface of the fertilizer. The 100kg product granule made in this way has the function of chemical fertilizer and the function of water absorption and water retention simultaneously.
Embodiment 3
[0035] Mix 0.2kg of potassium polyacrylate, a water storage material, in the pretreatment machine and add it into the nozzle hopper, add 99.5kg of compound fertilizer, 0.1kg of synergist and 0.1kg of borax granules into the drum implanter, and put the polyacrylic acid under the condition of rotation. The acrylic emulsion adhesive is coated on the surface of the fertilizer granules. After the coating is completed, the implanter is energized to generate static electricity on the granules. After the nozzle is moved close to the fertilizer granules, the nozzle is turned on to make the water-absorbing material fly to the surface of the fertilizer granules at high speed, and the granules are completed. Water storage materials are implanted on the surface of the fertilizer. The 100kg product granule made in this way has the function of chemical fertilizer and the function of water absorption and water retention simultaneously.
