Leonardite contains highly oxidized organic matter, various minerals accumulated throughout the year, spore-state archaea, polysaccharides, biopolymers, enzymes, and the like. The method for activating humic acid of weathered lignite by wind is more, and mainly comprises physical, chemical and biological methods, wherein the physical method mainly comprises mechanical crushing, ultrasonic treatment and the like; the chemical methods include acid-catalyzed oxidation, alkali-soluble acid-precipitation, and a method combining a metal catalyst and an acid-catalyzed oxidation. The humic acid has larger molecular weight, poorer chelating capacity and hard water resistance, easier formation of flocculent precipitate and the like, and causes the humic acid to have poorer effect on the synergism of fertilizer nutrients or the effect on stimulating the growth of crops.
On the other hand, with the development of the fertilizer industry, the application amount of the fertilizer is continuously increased, and the fertilizer plays an important role in promoting the continuous increase of agricultural production. But the problems of low utilization rate of the fertilizer and increased fertilizer feeding cost are also generally reflected. How to improve the utilization rate of the fertilizer is an important research topic for agricultural chemical workers. A small amount of humic acid substances with chemical activity and biological activity are added into nitrogen, phosphorus, potassium and trace element fertilizers, so that the utilization rate of the fertilizer can be improved to different degrees. A large number of researches prove that humic acid substances with chemical activity and biological activity are introduced into the fertilizer, and the fertilizer utilization rate is obviously improved through the functions of chemical combination, adsorption, chelation, biological stimulation and the like of the humic acid.
CN101024590B provides a preparation method of a humic acid-containing water-soluble fertilizer, wherein the humic acid adopts potassium humate to replace sodium humate, residual residues obtained by extracting the potassium humate can be used for improving soil and avoiding environmental pollution, and macroelement potassium is supplemented to the soil, and the fertilizer contains various stable trace elements and is a stable and comprehensive humic acid fertilizer. The invention comprises the following operation steps: 1. adding water and a raw material containing humic acid into a size mixing tank, adding an extracting agent potassium hydroxide, keeping the temperature between 50 and 60 ℃, mixing and extracting for 1 to 2 hours; centrifuging on a centrifuge, filtering to obtain potassium humate, and discharging residues through a conveyor belt; 2. dissolving raw materials such as nitrogen, phosphorus, potassium, boron, molybdenum and the like in water; 3. dissolving complexing agent in water, adding calcium, magnesium, copper, iron, zinc, manganese and other raw materials, heating, dissolving and complexing; 4. and mixing the materials prepared in the three steps in a finished product preparation tank, and emulsifying and grinding the mixture for 3 to 4 hours under the action of an emulsifying pump to obtain a finished product.
CN107337510A discloses a method for activating lignite humic acid and preparing a slow-release coated organic fertilizer thereof, which comprises the steps of oxidizing lignite by nitric acid to improve the content of lignite humic acid, improve the number of surface carboxyl groups and improve the adsorbability of ammonium ions, biologically activating lignite humic acid by using an enzyme preparation to enable lignite humic acid to be micromolecule, generating a series of reactions such as condensation, oxidation, degradation and the like under the action of ammonia water to nitride and dissolve lignite humic acid, proportioning and granulating the lignite humic acid with an organic decomposed fertilizer and an inorganic fertilizer, and coating the lignite humic acid with a coating agent prepared from gelatin, sodium cellulose, zeolite powder and soybean oil.
Because the demand for the fertilizer is continuously increased at present, the problem of the utilization rate of the fertilizer is more serious, and the humic acid also has an obvious effect on improving the effect of the fertilizer. Therefore, how to provide a fertilizer containing humic acid with high utilization rate becomes a problem to be solved urgently.
