Medical stone dual-effect multi-element silica, calcium and potassium fertilizer and preparation method thereof

Abstract

The invention discloses a medical stone dual-effect multi-element silica, calcium and potassium fertilizer and a preparation method thereof. The medical stone dual-effect multi-element silica, calcium and potassium fertilizer is produced by organically blending medical stone, calcium stone, bentonite, attapulgite, potassium oxide, magnesium sulfate, borax, zinc sulfate, magnesium sulfate, ferrous sulfate, aluminum potassium sulfate, agricultural traditional Chinese medicines (radish seed, celastrus angulatus, garlic juice, tobacco stalk, castor bean, onion juice and liquorice), a biological enzyme activator, a polyaspartic acid (PASP) plant nutrient accelerator, sodium nitrophenolate and the like. The preparation method breaks through the classic production technology frames home and abroad and comprises the following steps of: under the condition of normal temperature and normal pressure, crushing and milling the raw materials in the formula into powder of which the grain size is about 120 to 200 meshes; uniformly mixing the powder in a stirrer according to proportion; conveying the mixture to a granulator through a conveyor; after spraying and chelating the mixture through PASP and water mixed solution, granulating the mixture; after curing and drying the mixture with a dryer at high temperature, screening the grains, wherein the fertilizer product is 2.5 to 4.5mm in grain size, 5 to 6 Newtons in strength and less than 5 percent in free moisture; and after the product is checked to be qualified, metering and filling the product in bags. Fertilizer and medicine are integrated in the product; the product is comprehensive in nutrient elements, uniformly supplies fertilizer and is rich in organic substances and amino acids; residual fertilizer in the soil can be activated and used; the yield and the quality of crops are improved; green and organic agricultural products are produced; income of farmers is increased; the defect and difficulty brought to agricultural production and plantation by applying chemical fertilizers for a long time can be well overcome; the defects and the disadvantages of the chemical fertilizers are overcome; and the industry policy requirement of China on the economic benefit and social benefit of a green, organic and environment-friendly sustained or controlled release fertilizer is really met.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a medical stone double-effect multi-element silicon-calcium-potassium fertilizer and a preparation method thereof. Background technique [0002] There are 16 kinds of nutrient elements necessary for the growth of crops, and only when these 16 kinds of large, medium and trace elements are supplied to crops in a balanced and comprehensive manner, can the crops produce stable and high yields. At present, in my country's agricultural planting and production fertilizers, there has been a long-term focus on the application of nitrogen, phosphorus and potassium fertilizers, while ignoring the important role of reasonable supplementation of medium and trace element fertilizers, resulting in incomplete fertilizer nutrients in the production and application of fertilizers. , the unbalanced ratio of fertilizer elements, the single function of fertilizer, and the disjointed application of chemica...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of low fertilizer utilization rate, serious physiological diseases, large residual fertilizer, soil compaction, decreased fertilizer supply capacity, and agricultural Due to a series of problems in the background technology, such as high planting costs and difficulties in increasing farmers' production and income, a specially developed and produced one has comprehensive nutrients, balanced fertilizer supply, and integrated fertilizer and medicine. It can activate and utilize residual fertilizer in the soil, and improve soil compaction and the environment. Pollution, restore soil fertility, improve the utilization rate of fertilizers in the current season, solidify and utilize nitrogen in the air, ecologically prevent and control pests and diseases, improve crop resistance, reduce the input of chemical fertilizers and pesticides by more than 30%, save production and planting costs, and can absorb and dissolve Remove the pesticide residues and harmful elements in the fruits of agricultural products, improve the yield and quality of agricultural products, and increase the income of farmers. Multifunctional green and environmentally friendly slow-release fertilizer products to promote the rapid improvement and upgrading of agricultural production and planting levels in my country
