Problems solved by technology

However, most of the water storage materials made of water-absorbent resin are in the form of flocs and powders, and the specific gravity is also very light. If the water storage materials are directly applied in the field, it will consume a lot of human resources, which is very uneconomical and effective. poor method
[0004] Use existing fertilizer granules and water-absorbent resin materials to manufacture water-storage fertilizers. Because the water-storage materials themselves are light in specific gravity and are flocculent elastomers, they cannot be combined with fertilizer granules to form new products.
Therefore there is no report about the water storage fertilizer

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.

Abstract

The invention discloses a manufacturing method for a water storage fertilizer and a product thereof. The water storage fertilizer is prepared by the steps of: mixing water storage materials for producing the water storage fertilizer in a treater, mixing and coating granules of the water storage fertilizer in a static implanter and implanting into the water storage materials. The invention belongs to novel preparation technology for the water storage fertilizer and a novel product.

Description

technical field [0001] The invention relates to agricultural water storage materials and fertilizers, in particular to a manufacturing method and product of a novel water storage fertilizer. Background technique [0002] Various fertilizers are widely used in agricultural production, mainly elemental fertilizers such as urea, ammonium sulfate, potassium chloride, heavy calcium, etc., and multi-component compound fertilizers containing nitrogen, phosphorus, potassium and other nutrients. They are all granular fertilizers made through certain processes and equipment. They can provide various nutrients for plant growth. It has also contributed to the increase in production and income of farmers. But the growth of plants is inseparable from sunlight and water in addition to fertilizer nutrients. Especially in arid areas with little precipitation, it is not news to us that crops have been greatly reduced or lost due to lack of water. If we can provide fertilizer nutrients for ...
