Dampproof easily-absorbed magnetized slow-release fertilizer and preparation method thereof

Abstract

The invention discloses a dampproof easily-absorbed magnetized slow-release fertilizer and a preparation method thereof. The dampproof easily-absorbed magnetized slow-release fertilizer is prepared from, by weight, 45-65 parts of soybean oil sediments, 35-40 parts of peat soil, 160-190 parts of sesame meal, 10-12 parts of magnesium nitrate, 26-28 parts of potassium hydrogen phosphate, 250-280 parts of Chinese medicine residues, 23-25 parts of EDTA chelate boron, 80-100 parts of flyash, 55-60 parts of iron pyrite ash, 30-35 parts of cassava starch, 5-8 parts of lime acetate, 20-24 parts of a composite bacterial strain and a proper amount of water. According to the fertilizer, raw materials contain sufficient nitrogen, phosphorus and potassium which are greatly needed by plants, meanwhile the EDTA chelate boron and chelating liquid of a coated layer are utilized, it is beneficial for the plants to absorb various microelements, fermented granulation of the soybean oil sediments, the peat soil and the like serve as organic matter and an anti-blushing agent, dryness and stabilization of fertilizer particles can be guaranteed to the maximum degree, the service life of the fertilizer is prolonged, and effectiveness of fertilizer nutrients is maintained.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a moisture-proof, easy-absorbing, 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. T...

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.
