Magnetized slow release fertilizer for improving crop absorption capacity and preparation method thereof

Abstract

The invention discloses a magnetized slow release fertilizer for improving crop absorption capacity and a preparation method thereof. The magnetized slow release fertilizer is prepared from the following raw materials by weight: 250-280 parts of peanut meal, 8-10 parts of zinc chloride, 14-18 parts of potassium feldspar powder, 20-24 parts of calcium superphosphate, 170-190 parts of sawdust, 40-60 parts of pomegranate peel powder, 100-120 parts of fly ash, 75-85 parts of pyrite ash, 25-27 parts of cassava starch, 6-8 parts of calcium acetate, 14-17 parts of a composite biological agent, and a proper amount of water. After use, the fertilizer provided by the invention can magnetize the shallow soil layer soil, strengthen crop physiologic potential and cell magnetic potential, and adjust the in vivo enzyme activity of crops, thereby causing magnetochemical reaction and magnetobiological effect around soil and crop roots, promoting the nutrient absorption of crops, and improving organic matter synthesis and transformation and other metabolic activities in crops. All the effects are finally reflected in promotion of crop growth and development, yield increase and quality improvement.

Description

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

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.
