Problems solved by technology

[0002] In agricultural fertilization, fertilization is required at intervals after the crops are sown, and the duration of fertilization is short, so it is necessary to fertilize the crops frequently, increasing the workload of farmers, and it is not possible to fertilize at one time in order to reduce the amount of fertilization Too much, it is easy to cause the crops to die

Embodiment Construction

[0113] In order to further explain the technical solutions of the present invention, specific examples are given below to illustrate in detail.

[0114] A kind of improved soil fertilizer preparation technology of the present invention, such as Figure 1-Figure 14 shown, including the following steps:

[0115] a. Fermenting the raw materials;

[0116] b. Granulating the fermented raw materials to form fertilizer granules;

[0117] c. Sorting the fertilizer granules in a single manner and wrapping them with the first slow-release film layer;

[0118] d. Cover one layer of fertilizer layer outside the first slow-release film layer, and the fertilizer is made by mixing raw materials and foaming agent, and the fertilizer layer is heated to make the foaming agent foam;

[0119] e. Spray brightener outside the fertilizer layer to form a bright layer;

[0120] f. Wrap the second slow-release film layer outside the bright layer;

[0121] g, then transport bagging.

[0122] Prefe...

Abstract

The invention provides a soil-improving fertilizer preparation process, which comprises the following steps of: a, mixing solid raw materials and putting the mixture into a raw material pool; b, granulating the fermented raw materials to form fertilizer granules; c, singly sorting the fertilizer particles, and coating the fertilizer particles with a first slow-release film layer; d, covering the first slow-release film layer with a fertilizer layer ( the fertilizer is prepared by mixing the raw materials with a foaming agent), and heating the fertilizer layer to foam the foaming agent; e, spraying a brightening agent outside the fertilizer layer to form a brightening layer; f, coating the brightening layer with a second slow-release film layer; and g, carrying out transporting and bagging.According to the soil-improving fertilizer preparation process, two layers of fertilizers are formed through layer-by-layer coating, the outer-layer fertilizer can be decomposed and absorbed by soilfirstly, and after the outer-layer fertilizer is decomposed, the inner layer can be decomposed firstly and then is in contact with the soil for decomposition under the protection of the first slow-release film layer, so that the effect of interval decomposition is achieved, and interval fertilization is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural production of chemical fertilizers, in particular to a preparation process for improving soil fertilizers. Background technique [0002] In agricultural fertilization, fertilization is required at intervals after the crops are sown, and the duration of fertilization is short, so it is necessary to fertilize the crops frequently, increasing the workload of farmers, and it is not possible to fertilize at one time in order to reduce the amount of fertilization Too much, it is easy to cause the crops to die. [0003] In view of this, the inventor of this case conducted in-depth research on the above-mentioned problem, and then this case was produced. Contents of the invention [0004] The object of the present invention is to provide a kind of improved soil fertilizer preparation process that has two layers of fertilizer to delay fertilizer dissolving in soil. [0005] In order to achieve the...
