Safe high-yield magnetization slow-release fertilizer and preparation method thereof

Abstract

The present invention discloses a safe high-yield magnetization slow-release fertilizer and a preparation method thereof, the safe high-yield magnetization slow-release fertilizer is prepared from the following parts by weight of raw materials: 260-290 parts of soybean cake meal, 14-16 parts of silicon sulfate, 28-30 parts of calcium magnesium phosphate fertilizer, 130-150 parts of wheat bran, 60-80 parts of oil residue, 15-19 parts of attapulgite, 70-80 parts of fly ash, 55-65 parts of iron pyrite ash, 25-27 parts of tapioca starch, 6-7 parts of calcium acetate, 14-15 parts of a complex biological agent and the proper amount of water; the safe high-yield magnetization slow-release fertilizer is rich in N, P, K and other macronutrients needed for growth of crops, and free of the limitations of common fertilizers, fermentation humus contained in the safe high-yield magnetization slow-release fertilizer can improve the physical properties of soil, magnetization movement of fertilizer granules helps movement of crop root cells electrically-charged particles, adjustment of liquid crystal structures of biological molecules and changes in membrane permeability, metabolism process is promoted, cell growth is accelerated, and the purpose of high-yield of the crops can be achieved under the premise of ensurance of environmental safety of soil and water.

Description

Technical field

[0001] The invention relates to the technical field of fertilizers, in particular to a safe and high-yield 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. The use of ch...

[0019] Specific implementation plan

[0020] The present invention will be further described in detail below in conjunction with the following specific embodiments:

[0021] Weigh the following parts by weight (kg) of raw materials: soybean meal powder 280, silicon sulfate 15, calcium magnesium phosphate fertilizer 30, wheat bran 140, oil feet 70, attapulgite 17, fly ash 75, pyrite ash 60 , Tapioca starch 26, Calcium acetate 6, Compound biological inoculum 15, appropriate amount of water;

[0022] The compound biological inoculum includes sulfate reducing bacteria, isooxferric reducing bacteria and Bacillus subtilis, and the ratio is 1:1:2.

[0023] The specific steps for the preparation of the fertilizer are as follows:

[0024] (1) Put the fly ash in a high-temperature furnace, calcine it at 750°C for 20 minutes, take it out and cool it, put the pyrite ash into a high-temperature furnace, and burn it at 600°C for 30 minutes, take it out, and cool it down. Mix the two kinds of calcin...
