Soil salinization improvement magnetization slow-release fertilizer and preparation method thereof

Abstract

The present invention discloses a soil salinization improvement magnetization slow-release fertilizer and a preparation method thereof, the soil salinization improvement magnetization slow-release fertilizer comprises the following parts by weight of raw materials: 35-45 parts of powdered wood sugar, 140-160 parts of peanut meal, 8-10 parts of boron trisulfide, 190-210 parts of wheat bran, 13-15 parts of MgSO4.KCl.x H2O, 20-24 parts of sodium pyrophosphate, 90-110 parts of fly ash, 65-75 parts of pyrite ash, 24-28 parts of tapioca starch, 5-7 parts of calcium acetate, 10-15 parts of a compound biological agent, and proper amount of water; the fertilizer is prepared by fully rotting the wheat bran, peanut meal and the like, and can effectively dilute the soil salt content, after magnetization, soil magnetic field effect can be enhanced, soil water solubility and permeation can be improved, and more salts are dissolved in water and down infiltrated into soil deep layer, so that salt content of a leakage liquid is increased, soil desalination rate and salt washing effect are improved, salt and alkali content of plough layer soli is decreased, and a more favorable environment is created for the growth 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 salinization 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.
