Making and production process for animal and plant type organic fertilizer

Abstract

The invention relates to a making and production process for an animal and plant type organic fertilizer. The preparation method comprises an animal fertilizer preparation process, a plant fertilizer preparation process, and an organic fertilizer preparation process, and specifically includes: S1. drying (or airing) a starter and a metered animal raw material under the action of a planer to obtain an animal fertilizer; S2. under the action of the planer, drying (or airing) a starter and a metered plant raw material to obtain a plant fertilizer; and S3. mixing and stirring the products of S1 and S2, and then carrying out extrusion granulation, polishing, drying, cooling, screening, metering, packaging and the like to obtain an organic fertilizer. The raw materials of the invention mainly come from decomposed plant and (or) animal carbon-containing organic materials, which can improve the soil fertility, supply plant nutrition, enhance crop quality, increase yield, control pest, and is environment-friendly and pollution-free, etc.

Description

technical field [0001] The invention discloses the preparation and production process of animal and plant type organic fertilizers. It belongs to the technical field of fertilizers. Background technique [0002] At present, the common organic fertilizers in the market can be summarized as the following situations: [0003] 1. Large chemical fertilizer + humic acid = organic fertilizer. The characteristics of this type of fertilizer are: [0004] 1. The cost of raw materials is low, easy to process, low ex-factory price, and dominant in the market; [0005] 2. In the early stage, due to the large chemical fertilizer, the effect was obvious, but in the later stage of the comparative test, there was a phenomenon of defertilization; [0006] 3. Humic acid can improve crop quality. [0007] 2. Large chemical fertilizer + waste = organic fertilizer, the characteristics of this type of fertilizer: [0008] Urban domestic garbage, solid waste, and chemical waste (drug residue)....

AI Technical Summary

Problems solved by technology

[0005] 2. In the early stage, due to the large chemical fertilizer, the effect was obvious, but in the later stage of the comparative test, there was a phenomenon of defertilization;

[0011] 2. This kind of raw material contains a lot of salt, which will cause soil salinization when used in large quantities for many years, which will increase the critical point of the fertilizer effect of nutrients on crops and increase the amount of fertilizer applied;

[0012] 3. Nitrogen is mainly nitrogen in the form of uric acid. Urate cannot be directly absorbed and utilized by crops. When it decomposes in the soil, it consumes a lot of oxygen and releases a lot of carbon dioxide gas, which is easy to damage the roots of crops;

[0013] 4. There are more germs and eggs, and it is easy to cause pests and diseases;

[0014] 5. There is a problem of excessive trace elements. A large amount of trace elements added to livestock and poultry feed are not completely absorbed by livestock and poultry, and most of them are accumulated in feces;

[0015] 6. The residual content of this kind of API and the content of heavy metals are relatively high, which may cause environmental pollution when applied to the soil

[0016] In summary, the existing organic fertilizers have shortcomings such as defertilization, damage to crop roots, easy to cause insects, heavy metals, pesticides and heavy metal residues, harmful to health, and soil pollution.
