40kHz。
The beneficial effects of the invention are as follows：
（1）The present invention hydrolyzes to obtain sulfuric acid ammonium type amino acid fertilizer from tanning waste shavings, then with flyash, humic acid, sulphur
Iron Ore Powder and gangue are raw material, and compound organic matter and N P and K, silico-calcium iron are produced through bacillus megaterium fermentative degradation
Composite base-material, then nanoscale base-material is formed through high temperature sintering, most mixed afterwards after magnetization modification with sulfuric acid ammonium type amino acid fertilizer
Concentration, stability synergy fertilizer is made, fertilizer nutrient and composite components produced by the present invention reach nano scale level, due to nanometer base-material
Small-size effect make fertilizer band magnetic effect, nutrient can be made to be more easy to be absorbed by plants in the presence of biological magnetic field, be advantageous to plant
Thing grows, in addition, have many dangling bonds around its surface atom, it is highly active, due to skin effect, make nanostructured fertile
Expect surface energy, Surface binding energy increase, absorbed beneficial in soil by root system of plant, improve the effect of Fertilizer application, nanometer
Structure fertilizer can also stimulate plant growth, improve the activity of a variety of enzymes in plant, improve crop yield, reach fertilizer synergistic mesh
's；
（2）Magnetic Nano base-material in fertilizer of the present invention crystallizes to be formed by hydrogen bond association mechanism with sulfuric acid ammonium type amino acid fertilizer
Eutectic, in the loose structure of sulfuric acid ammonium type amino acid fertilizer, inserts magnetic Nano base-material, change the loose knot of itself
Structure, make structure even closer, be changed into ordered structure from unordered, so that the heat endurance of amino acid fertilizer and water stability all obtain
To improve, volatility declines, while ammonium nitrogen can be delayed to change into the process of nitrate nitrogen, and then reduces nitrous oxide emission amount,
Nitrogen utilization efficiency improves, in addition, the fertilizer can increase absorption and solidification of the soil to ammonium ion, it is adsorbed and solidification amount
Increase, it is not likely to produce leaching loss and is lost in and lose so that fertilizer stability improves, and has broad application prospects.
