Abstract
The invention relates to the field of compound fertilizers, and particularly relates to a low-cost slow-release compound fertilizer containing an okra seed. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of kieselguhr of 1250-2000 meshes, 12-14 parts of potassium chloride, 8-10 parts of ordinary superphosphate, 25-28 parts of urea, 6-8 parts of ammonium hydrogen carbonate, 12-15 parts of diammonium hydrogen phosphate, 2-4 parts of sodium tetraborate, 12-15 parts of earthworm cast, 18-20 parts of pond silt, 8-10 parts of tea pulp, 2-4 parts of shrimp shell meal, 1-2 parts of sodium naphthaleneacetate, 4-5 parts of Chinese cabbage dreg, 2-3 parts of amino-oligosaccharin, 6-8 parts of okra seed, 10-12 parts of water-dispersible epoxy modified acrylate resin solution, 1-3 parts of dimethyl silicone oil, 1-2 parts of sodium caseinate, 2-3 parts of Pulullan, 2-4 parts of zinc gluconate, 6-8 parts of table vinegar and 4-5 parts of assistant. According to the invention, the compound fertilizer is wide in raw material sources, cheap and accessible; and by technically using the kieselguhr and the coating agent, the nutrients are doubly coated, so that the nutrients (especially minor elements) therein can be effectively protected, and the fertilizer efficiency can last longer. Besides, the compound fertilizer can improve the yield and quality of crops, thereby truly realizing low cost and high profit.
Description
technical field [0001] The invention relates to the field of compound fertilizers, in particular to a low-cost slow-release compound fertilizer containing okra seeds. Background technique [0002] In modern agricultural production, compound fertilizer can be seen everywhere. It has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, and convenient storage and application. It plays an important role in promoting high and stable crop yields. Slow-release compound fertilizer is an important category of compound fertilizers, and it is also the focus of research on the development of my country's chemical fertilizer industry. Its slow-release principle is to coat a thin layer of hydrophobic substances on the surface of fertilizer particles, so that the internal nutrients are slowly released to the In the soil, nutrients are continuously supplied to crops, which effectively improves the utilization rate of fertilizers. However, the...
