Abstract

The invention relates to the technical field of fertilizer preparation, in particular to a preparation method of high-stability synergistic fertilizer. The preparation method comprises the following steps: hydrolyzing leather meal, serving as tannery waste, to obtain ammonium sulfate amino acid fertilizer; fermenting and degrading coal ash, humic acid, pyrite powder and coal gangue, serving as rawmaterials, with bacillus megatherium; sintering at a high temperature; lastly, performing magnetization modification on a degradation product, mixing the degradation product with the ammonium sulfateamino acid fertilizer, and condensing the mixture to prepare the stable synergistic fertilizer. The nutrients and composite components of the prepared fertilizer are up to the nanoscale standard; thefertilizer has a magnetic effect due to the small size effect of a nanometer base material, so that the nutrients are easier to be absorbed by plants under the action of a biological magnetic field,and the growth of the plants is facilitated; moreover, a plurality of dangling bonds exist around surface atoms, so that the fertilizer has very high activity and, the absorption of the fertilizer byplant root systems in soil is facilitated, and the using effect of the fertilizer is enhanced; the nano-structure fertilizer can also simulate the growth of the plants, thereby increasing the activityof a plurality of enzymes in the plants, increasing the crop yield, and fulfilling the aim of enhancing the effect of the fertilizer.

Description

Technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a method for preparing a high-stability synergistic fertilizer. Background technique [0002] In the past 40 years, the world's chemical fertilizer application has increased by 15 times, while the grain output has only increased by 3 to 4 times. One of the main reasons is that ordinary chemical fertilizers have large nutrient leaching losses and large losses, resulting in low fertilizer utilization. According to the statistics. The seasonal utilization rate of chemical fertilizers in my country is 30% to 35% for nitrogen, 10% to 25% for phosphorus, and 35% to 50% for potassium, which are far below the level of developed countries in the world. [0003] Amino acids are a class of organic compounds containing amino and carboxyl groups. They are the basic unit of protein. They have complexing ability and can complex with metals to form relatively stable complexes. They are ...
