Abstract

The invention discloses a special fertilizer for paddy rice. The special fertilizer is prepared by carrying out a coating process on the following raw materials by weight: 1.5-3 parts of compound coating powder, 4-6 parts of tung oil, 5-8 parts of paraffin wax, 12-15 parts of urea, 54-60 parts of calcium superphosphate, 15-24 parts of potassium chloride, 1-2 parts of zinc phosphate, 0.5-1.5 parts of indian stringbush root powder, 1-2 parts of paulownia saw powder and 0.5-1.5 parts of diatomite, wherein the compound coating powder is prepared by the following raw materials by weight: 1-2 parts of calcium carbonate, 1-2 parts of iron sand, 1-2 parts of dolomite, 1-2 parts of potassium feldspar, 2-4 parts of mineral slag, 3-5 parts of peat soil, 1-2 parts of thunder god vine powder and a proper amount of plant oil. Various nutrient elements required for growth of the paddy rice are reasonably compounded to prepare the compound fertilizer having the advantages of light weight, water retention, fertility maintenance and good slow release performance.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special fertilizer for rice. 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 or irrigated areas where nutrients are...
