Embodiment 1

[0056] Embodiment 1, the preparation of multifunctional slow-release fertilizer

[0057] (1) Preparation of surface-coated organic bacterial fertilizer particles with dopamine attached

[0058] Pulverize straws, dead leaves, subtilis, etc. through a 500-mesh sieve to obtain organic waste powder; add 50 g of the organic waste powder to 1 L of water, add 10 g of Bacillus subtilis powder, and mix to obtain an organic waste bacterial liquid; add 1.5 g of Tris to In the organic waste bacterial solution, the pH value of the organic waste bacterial solution is adjusted to 8-8.5 with 6M HCl to obtain a Tris-HCl buffer solution. 5 g of dopamine hydrochloride was added, stirred at room temperature for more than 12 hours, and suction filtered to obtain organic bacterial fertilizer particles coated with dopamine and adhered to the surface, and the organic bacterial fertilizer particles were composed of the organic waste powder and Bacillus subtilis.

[0059] (2) Coating superabsorbent po...

Embodiment 2

[0063] Embodiment 2, the performance of multifunctional slow-release organic bacterial fertilizer

[0064] (1) Water absorption and water retention performance test of slow-release organic bacterial fertilizer

[0065] Take the multifunctional slow-release organic bacterial fertilizer prepared according to the method described in Example 1, and test the absorption capacity (g / g / g), and the water retention rate (wt%) after 12 hours, the test results are shown in Table 1.

[0066] Table 1

[0067]

[0068] The results in Table 1 show that the multifunctional slow-release organic bacterial fertilizer prepared by the method described in Example 1 has excellent water absorption and water retention properties, and with the increase of temperature, the water absorption capacity is on the rise. Therefore, the slow-release fertilizer can effectively Avoid rapid evaporation or release of water and fertilizer in soil and fertilizer, especially in summer and noon with high temperatu...

Abstract

The present invention provides a multifunctional slow-release organic bacterial fertilizer. The organic bacterial fertilizer comprises organic matters, bacteria beneficial to plant growth, dopamine ora salt thereof, a high polymer molecule, sodium alginate and Ca<2+>. The dopamine is attached to the surfaces of the organic matters and beneficial bacteria; then the surface of the dopamine is covered with the high polymer molecule; finally, the surface of the high polymer molecule is coated with the sodium alginate and Ca<2+>; and thus the organic bacterial fertilizer capable of maintaining fertilizer with water of soil and slowly releasing live bacteria to a certain extent is prepared. The slow-release organic bacterial fertilizer can effectively maintain the fertilizer with the water of the soil and slowly release the live bacteria, thereby improving the utilization efficiencies of the fertilizer with the water and the living bacteria, improving disease resistance and stress resistance of crops, improving the soil fertility condition sustainably, and realizing efficient reuse of bio-organic waste materials. The provided slow-release organic bacterial fertilizer is simple and environmentally-protective in the preparation technology, free of organic solvents and suitable for industrial mass production applications.

Description

technical field [0001] The invention belongs to the technical field of fertilizer development, and in particular relates to a multifunctional slow-release organic bacterial fertilizer. Background technique [0002] Organic fertilizers refer to organic fertilizers derived from plant or animal residues, which are used to provide plant nutrients and effectively improve soil physical, chemical and biological properties. Organic fertilizers have comprehensive nutrients, and through their own decomposition process, they can fertilize and improve the soil for the needs of plant growth and development. [0003] Bacterial manure, as a kind of biological fertilizer, can improve the nutritional conditions and nutrient supply of crops through the life activities of microorganisms, such as fixing nitrogen in the air, accelerating the absorption and transformation of nutrients, and inhibiting the activities of harmful microorganisms in agricultural production. Used a lot. [0004] Water...
