Multifunctional fertilizer and preparation method thereof

Abstract

The invention relates to the field of agricultural planting and discloses multifunctional fertilizer and a preparation method thereof. The multifunctional fertilizer comprises a quick release layer, a slow release layer and an envelope layer, wherein the quick release layer is composed of the following substances: nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, microelement fertilizer, a chemical oxygen increasing agent, a natural antibacterial plant extract, a seaweed-aloe compound gel carrier, modified calcium oxide and a binding agent; the slow release layer is composed of the following substances: nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, microelement fertilizer, the chemical oxygen increasing agent, the natural antibacterial plant extract, modified beta-cyclodextrin and the balance of the binding agent; and the envelope layer is alcohol-soluble macromolecule resin. The multifunctional fertilizer disclosed by the invention has the functions of bacterium resistance, oxygen increase, immunity enhancement and slow release. The multifunctional fertilizer disclosed by the invention has the advantages that an antibacterial ingredient is utilized as a carrier of fertilizer, an oxygen increasing ingredient and the like and has antibacterial, oxygen-increasing and slow-release effects; and the antibacterial carrier is a substance harmless to the environment and human body.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a multifunctional fertilizer and a preparation method thereof. Background technique [0002] Existing agricultural fertilizers are generally added with a variety of functional additives, including insecticides, growth promoters, antibacterial agents, oxygenates, herbicides, soil conditioners, and so on. [0003] Among them, insecticides, antibacterial agents, etc. are currently commonly used artificial chemical synthesis reagents. For example, commonly used insecticides include dinotefuran, clothianidin, thiacloprid, imidacloprid, etc. Commonly used antibacterial agents are Chlorothalonil, Methiamycin, Wanmexazol and so on. Although these reagents have significant insecticidal and antibacterial capabilities, they tend to remain in plants and soil, which are harmful to humans and not environmentally friendly. For edible crops such as fruits and vegetables, a high amount of p...

AI Technical Summary

Problems solved by technology

The fertilizer of this patent contains chemically synthesized bacterial blight antibacterial agent, which will cause some problems mentioned above

[0005] In addition, fertilizer additives such as pesticides, antibacterial agents, oxygenates, herbicides, and soil conditioners are generally added during the fertilizer preparation process. If the fertilizer is to have multiple functions at the same time, it needs to be added during the preparation process. A variety of additives will cause the production process to be too complicated and the cost will be higher

[0006] On the other hand, although the existing fertilizers with slow-release function prolong the duration of slow-release to a certain extent, the release rate in the initial stage is still high, resulting in shortened slow-release time; The reduction of the release power is seriously insufficient, resulting in the subsequent slow-release effect is not obvious
