Embodiment Construction

[0017] A preparation method of special fertilizer for paddy base fertilizer, comprising the following steps:

[0018] (1) Mix 3kg of calcium carbonate, 4kg of iron ore, 1kg of dolomite, 1.5kg of potassium feldspar, and 1kg of slag, and burn them at 500°C for 6 hours, then grind them into nanopowder, and mix with 2kg of fly ash by weight After the parts are mixed, the compound powder is ready for use;

[0019] (2) First add animal hair to 30% sulfuric acid and hydrolyze it at 100-110°C for 1-2 hours to generate amino acids, then add lime to neutralize to a pH value of 6.0-6.8 to obtain a hydrolyzate, add 4kg per 15kg of hydrolyzate Carboxymethyl cellulose, then add 1kg of ferrous sulfate and 4kg of ammonium molybdate to dissolve, and react at 90-105°C for 5-6 hours to obtain the amino acid chelating solution for subsequent use;

[0020] (3) Mix 8kg of urea, 45kg of superphosphate, 10kg of potassium chloride, 1kg of zinc sulfate, 1kg of cnidium powder, 1kg of bamboo charcoal po...

Abstract

The invention discloses a preparation method of a special fertilizer for a rice base fertilizer, which comprises the following steps: evenly mixing 8-10 parts by weight of urea, 45-50 parts by weight of calcium superphosphate, 8-10 parts by weight of potassium chloride, 1-2 parts by weight of zinc sulfate, 1-2 parts by weight of cnidium fruit powder, 1-3 parts by weight of bamboo carbon powder, 1-3 parts by weight of triperygium wilfordii powder and 3-5 parts by weight of compound powder, spraying 2-4 parts by weight of amino acid chelation solution and 4-5 parts by weight of bonding solution, and granulating to obtain compound fertilizer granules; and spraying 7-10 parts by weight of molten paraffin on the surface of 100 parts by weight of compound fertilizer granules for coating, thereby obtaining the product. The compound fertilizer prepared by reasonably compounding various nutrient elements required by rice growth has the advantages of light weight, and excellent water retention, fertilizer retention and slow release properties.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a method for preparing a special fertilizer for rice base fertilizer. Background technique [0002] Coated fertilizers are also called coated fertilizers and film fertilizers. Fertilizers made of quick-acting fertilizer granules wrapped with semi-permeable or impermeable film substances. Film-forming substances include plastics, resins, paraffin, polyethylene and elemental sulfur. The purpose of the coating is to slowly release the quick-acting nutrients in the coated fertilizer after it is applied to the soil, so as to prolong the fertilizer effect. The release rate depends on the type of coating, thickness, particle size, fertilizer solubility, soil temperature, soil water content, and soil microbial activity. It is suitable for crops with high economic value, long growth period, large amount of fertilizer but inconvenient to fertilize in batches, and high temperature, rainy areas...
