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.

Embodiment 1

[0029] A kind of preparation method of organic-inorganic compound slow-release stick fertilizer, as attached figure 1 As shown: the organic-inorganic compound slow-release stick fertilizer is a cylinder composed of an inner core 2, a slow-release film 3 and an outer shell; the inner core 2 is a cylinder coaxial with the organic-inorganic compound slow-release stick fertilizer , and the outer periphery of the inner core 2 is covered with a layer of slow-release film 3; the outer periphery of the sustained-release film 3 is covered with a shell; the shell is composed of a base 5, a shell 4 and a top cover 1; wherein, the inner core 2 It is made by mixing inorganic fertilizers and auxiliary additives; the shell is made of organic fertilizers; specifically, the following materials are selected and pressed according to the following steps:

[0030] (1) Material selection

[0031] ① Inorganic fertilizers use N-P 2 o 5 -K 2O ratio is the commercialized compound fertilizer of 15%-...

Embodiment 2

[0045] A method for making organic-inorganic compound slow-release stick fertilizer, the structure of the organic-inorganic compound slow-release stick fertilizer is the same as that of Example 1; and its inner core is also made by mixing inorganic fertilizer and auxiliary additives The shell is also made of organic fertilizer; it is specifically selected from the following materials, and is formed by pressing according to the following steps:

[0046] (1) Material selection

[0047] ①Inorganic fertilizers use powdered urea (N≥46.3%), monoammonium phosphate (N≥12%, P 2 o 5 ≥61%), potassium chloride (K 2 O≥62%), the total amount of which accounts for 43% by weight of the organic-inorganic compound slow-release stick fertilizer;

[0048] ②Auxiliary additives are selected as a mixture of copper sulfate, zinc sulfate, ferrous sulfate, molybdenum sulfate, and fulvic acid, wherein the amount of each substance accounts for 0.4%, 0.4%, and 0.4%, 0.4%, 0.3%, 1.5%.

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 preparation method of the organic-inorganic compound slow-release stick fertilizer. Background technique [0002] The soil quality of large trees in urban gardens in my country, especially street trees, is poor, and there are serious physical structure problems such as compactness, airtightness, and watertightness, as well as low nutrient problems, which limit the normal growth of large trees and affect the landscape benefits of large trees. and ecological benefits. Due to the special conditions of the growing environment, man-made soil excavation is often used for fertilization at present. However, there are many problems in the common man-made soil fertilization method, such as difficult operation, affecting the green space landscape, limited fertilization amount, and low fertilization efficiency. In response to these problems, relevant resea...
