Multifunctional and dual-action compound medical stone fertilizer and preparation method thereof

Abstract

The invention discloses a multifunctional and dual-action compound medical stone fertilizer and a preparation method thereof. The fertilizer is obtained by compounding medical stone, bentonite, attapulgite, magnesium sulfate monohydrate, superphosphate, borax, zinc sulfate, aluminium potassium sulfate, agricultural traditional Chinese medicine (asparagus, liquoric root, yellow azalea, dalmatian chrysanthemum, melia toosendan, trifoliate jewelvine root or stem, Chinese stellera root, litsea cubeba, magnolia biloba and tobacco stem powder) components, a polyaspartic acid (PASP) plant nutrient accelerator, a sodium naphthalene acetate plant growth regulator and the like. The preparation method comprises the following steps of: crushing various raw materials in the formula to 150 to 250 meshes; uniformly mixing the crushed raw materials according to the proportion requirement of the fertilizer; spraying mixed solution of PASP and sodium naphthalene acetate onto the mixture, chelating and pelletizing; curing and drying; and screening to obtain a fertilizer product of which the particle size is between 2.5 and 4 millimeters, the intensity is 5 to 6 Newton and the free water content is less than 3 percent. The product integrates fertilizers with medicaments, has comprehensive nutrient elements, supplies nutrients uniformly, can activate and utilize residual fertilizers in soil and enhances the yields and the quality of crops.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a medical stone multi-functional double-effect multi-component 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 China'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 chemical fertilize...

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
