Magnetization slow-release fertilizer capable of improving soil structure and preparation method thereof

Abstract

The invention discloses a magnetization slow-release fertilizer capable of improving soil structure and a preparation method thereof. The magnetization slow-release fertilizer capable of improving the soil structure is made from raw materials with parts by weight: sugar beet pulps 240-270, copper sulfate powder 9-11, ammonium chloride 14-16, sawdust 80-100, fish meal 40-60, sodium selenite 8-10, fly ash 95-105, pyrite ash 60-70, cassava starch 26-30, calcium acetate 4-6, composite bacterial strains 13-18 and moderate water. The novel magnetization slow-release fertilizer capable of improving the soil structure respectively magnetizes solid of fertilizer granular and magnetizes liquid of an enveloped liquid, can improve crop yield and fertilizer utilization rate in same fertilizer input by mixing magnetic carriers, nitrogen, phosphorus, potassium and microelement and the like according to a proportion, improves soil nutrient condition and quality of agricultural products, and has important significance for improving farmer income and promoting agricultural development.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a magnetized slow-release fertilizer for improving soil structure and a preparation method thereof. Background technique [0002] my country is a typical large agricultural country with a large population and little arable land, and chemical fertilizers play a very important role in the production of crops. 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 state phosphorus with iron, aluminum oxides, etc., and gradually lose their effectiveness. These factors will reduce the utilization rate of fertilizer application. The u...

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.
