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

Abstract

The invention discloses a magnetization slow-release fertilizer capable of improving soil microbial ecology and a preparation method thereof. The magnetization slow-release fertilizer capable of improving the soil microbial ecology is made from raw materials with parts by weight: egg shells 50-70, fulvic acid potassium 26-29, ammonium bicarbonate 23-26, furfural residues 260-270, grass carbon 190-210, sodium hydrogen sulfite 8-14, fly ash 100-110, pyrite ash 80-90, cassava starch 26-30, calcium acetate 4-8, composite bacterial strains 13-17 and moderate water. The magnetization slow-release fertilizer capable of improving the soil microbial ecology adds various magnetotactic microorganisms, various different kinds of beneficial magnetotactic microorganisms also exist in soils simultaneously, the magnetization slow-release fertilizer capable of improving the soil microbial ecology can affect activity of the beneficial magnetotactic microorganisms through magnetization of fertilizers by adopting organic humus in the fertilizers as a nutrient source, improves activity of proteins and enzymes, and enhances activity of microorganisms, thereby promoting organic matters in the soils to resolve, and improving the content of absorbable nutrients of crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a magnetized slow-release fertilizer for improving soil microecology 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. Th...

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.
