[0019] specific implementation plan

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

[0021] Take the following raw materials by weight (kg) and make: rapeseed cake powder 220, calcium ammonium nitrate 25, potassium dihydrogen phosphate 33, bagasse 170, actinolite powder 18, zinc sulfate powder 8, fly ash 75, sulfur Iron ore ash 50, tapioca starch 22, calcium acetate 5, compound biological agent 11, appropriate amount of water;

[0022] The composite biological agent includes sulfate-reducing bacteria, isoxiric iron-reducing bacteria and Bacillus subtilis in a proportion of 1:1:2.

[0023] The concrete steps of the preparation of described fertilizer are as follows:

[0024] (1) Put the fly ash in a high-temperature furnace, calcinate at 850°C for 20 minutes, take it out and cool it, then put the pyrite ash into the high-temperature furnace, calcinate it at 550°C for 30 minutes, take it out and ...

Abstract

The present invention discloses a heavy metal harm reducing magnetization slow-release fertilizer and a preparation method thereof, the magnetization slow-release fertilizer comprises the following parts by weight of raw materials: 200-240 parts of rapeseed cake powder, 24-26 parts of calcium ammonium nitrate, 30-35 parts of potassium dihydrogen phosphate, 160-180 parts of bagasse, 15-20 parts of actinolite powder, 7-9 parts of zinc sulfate powder, 70-80 parts of fly ash, 45-55 parts of pyrite ash, 20-24 parts of tapioca starch, 4-6 parts of calcium acetate, 10-12 parts of a complex biological agent and proper amount of water; the magnetization slow-release fertilizer is prepared in inorganic and organic mixing manner, can effectively improve the nutrient content of the fertilizer, through double magnetization of the fertilizer and activation of the actinolite powder and other raw materials, crop root superoxide dismutase and catalase activity can be significantly improved, oxidative stress caused by residual heavy metals in soil can be eliminated, the integrity of root cell membranes can be maintained, plant tolerance to heavy metals can be enhanced, plants can be prevented from harm and harm to plants can be reduced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a magnetized slow-release fertilizer which reduces the harm of heavy metals 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 applicati...
