A kind of preparation method of organic-inorganic compound slow-release stick fertilizer

Abstract

The invention relates to a manufacturing method for an organic-inorganic compound slow-release fertilizer rod. The manufacturing method comprises the following steps: compacting organic fertilizer to form the outer layer of the fertilizer rod; coating the inner wall of the outer layer with a slow-release membrane; injecting inorganic fertilizer and multifunctional auxiliary additives into the inner layer of the fertilizer rod; carrying out capping with organic fertilizer; and then carrying out final pressing so as to obtain the organic-inorganic compound slow-release fertilizer rod. The manufacturing method is simple to operate, can prepare the organic-inorganic compound slow-release fertilizer rod with a specific structure and allows the organic-inorganic compound slow-release fertilizer rod to have the advantages of high organic nutrient content, slow release of inorganic nutrients, sufficient and long-lasting fertilizer efficiency, etc.

Description

Technical field [0001] The invention relates to a novel organic-inorganic compound slow-release stick fertilizer, in particular to a manufacturing method of an organic-inorganic compound slow-release stick fertilizer. Background technique [0002] The soil quality of big trees in urban gardens in my country, especially street trees, is poor, and there are serious physical structure problems such as compaction, airtightness and impermeability, as well as low nutrients, which limit the normal growth of big trees and affect the benefits of the big trees. And ecological benefits. Due to its special growth environment conditions, artificial soil excavation is often used to fertilize. However, ordinary artificial soil excavation and fertilization methods have many problems, such as difficult operation, impact on the green landscape, limited fertilization, and low fertilization efficiency. In response to these problems, relevant researchers have developed a new type of fertilizer, stick...

Problems solved by technology

However, most of the organic-inorganic compound slow-release fertilizers produced by these methods are granular fertilizers, and they cannot be processed into organic-inorganic compound slow-release stick fertilizers or the processed stick fertilizers cannot meet the requirements for use. -Inorganic materials are mixed to make rods and then coated. This production method will also cover organic fertilizers, thereby limiting the improvement of organic components in the physical structure of the soil.

In addition, in the existing preparation methods, there is also a production process of mixing organic materials and inorganic materials, and then pressurizing them with high-strength machinery to make bar fertilizers. However, the organic-inorganic compound bars produced by this method Among the fertilizers, due to the good water solubility of inorganic fertilizers, the organic fertilizer components have limited fertilizer retention capacity, so the inorganic fertilizers are easy to lose and cannot play a long-term role.
