Efficient organic fertilizer preparation device and process

Abstract

The invention provides an efficient organic fertilizer preparation device which sequentially comprises a fermentation device for storing and fermenting raw materials, a granulator for granulating thefermented raw materials to form a fertilizer, and a first film laminating machine for covering the outer layer of fertilizer granules with a first layer of film. According to the efficient organic fertilizer preparation device, through effective cooperation of all equipment, double-layer fertilizer particles are produced, the effect of interval decomposition is achieved, and therefore interval fertilization is achieved. An efficient organic fertilizer preparation process comprises the following steps of: a, fermenting raw materials; and b, granulating the fermented raw materials to form fertilizer granules. According to the efficient organic fertilizer preparation process, two layers of fertilizer are formed through layer-by-layer coating, the outer-layer fertilizer can be decomposed and absorbed by soil firstly, and after the outer-layer fertilizer is decomposed, the inner layer can be decomposed firstly and then makes contact with the soil for decomposition under the protection of the first layer of film, 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] One object of the present invention is to provide an improved soil fertilizer preparation device which has two layers of fertilizer to delay the dissolution of the fertilizer in the soil. [0005] Its second obj...
