Safe high-yield magnetization slow-release fertilizer and preparation method thereof

Abstract

The present invention discloses a safe high-yield magnetization slow-release fertilizer and a preparation method thereof, the safe high-yield magnetization slow-release fertilizer is prepared from the following parts by weight of raw materials: 260-290 parts of soybean cake meal, 14-16 parts of silicon sulfate, 28-30 parts of calcium magnesium phosphate fertilizer, 130-150 parts of wheat bran, 60-80 parts of oil residue, 15-19 parts of attapulgite, 70-80 parts of fly ash, 55-65 parts of iron pyrite ash, 25-27 parts of tapioca starch, 6-7 parts of calcium acetate, 14-15 parts of a complex biological agent and the proper amount of water; the safe high-yield magnetization slow-release fertilizer is rich in N, P, K and other macronutrients needed for growth of crops, and free of the limitations of common fertilizers, fermentation humus contained in the safe high-yield magnetization slow-release fertilizer can improve the physical properties of soil, magnetization movement of fertilizer granules helps movement of crop root cells electrically-charged particles, adjustment of liquid crystal structures of biological molecules and changes in membrane permeability, metabolism process is promoted, cell growth is accelerated, and the purpose of high-yield of the crops can be achieved under the premise of ensurance of environmental safety of soil and water.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a safe and high-yield magnetized slow-release fertilizer and a preparation method thereof. Background technique [0002] my country is a typical agricultural country with a large population and a small area of ​​arable land, and chemical fertilizers play a very important role in the production of crops. According to research, various physical and chemical changes will occur in the nitrogen, phosphorus, potassium and other nutrients applied to the soil. Among them, nitrogen will be lost through volatilization, leaching, denitrification, etc., while phosphorus is easily affected by Al in the soil. 3+ , Fe 3+ And Ca 2+ , Mg 2+ Various ions are fixed to form stable precipitates or form closed storage state phosphorus with iron and aluminum oxides, and gradually lose their effectiveness. These factors will cause the utilization rate of fertilizer application to decrease. The use of ch...

AI Technical Summary

Problems solved by technology

According to the research, the nitrogen, phosphorus, potassium and other nutrients applied to the soil will undergo various physical and chemical changes, among which nitrogen will be lost through volatilization, leaching, denitrification, etc., and phosphorus is easily absorbed by Al in the soil. 3+ , Fe 3+ and Ca 2+ , Mg 2+ and other ions are fixed to form stable precipitates or form closed storage phosphorus with iron, aluminum oxides, etc. and gradually lose their effectiveness

These factors will lead to a reduction in the utilization rate of chemical fertilizers

The use of chemical fertilizers will also bring environmental pollution, such as the greenhouse effect, eutrophication of water bodies, etc.
