Organic fertilizer produced by means of animal waste and production method thereof

Abstract

The invention provides organic fertilizer produced by means of animal waste. The organic fertilizer comprises core bodies composed of pig feces, cow feces and straw ash, the proportion of the components of the core bodies is 10 to 3 to 1, the core bodies are covered with shells, and the shells are straw powder shells. A production method of the organic fertilizer is further provided. Nitrogen fertilizer and potassium fertilizer are provided at the same time by means of the mixed feces. The mixed feces is easy to shape through addition of the straw ash. By means of the shells, the core bodies are insulated from the air after production is completed, so that the core bodies are fermented and decomposed in the shells after production is completed, and the production efficiency is improved. The shells can be produced by mixing straw powder with corn meal, the shells are slowly decomposed after fertilization, so that the organic fertilizer is slowly released into the soil, and long-acting fertilizer is provided for farmland. Fermentative bacteria go into the mixed feces after production is completed, decomposition is conducted, the pig feces is thoroughly decomposed effectively, and lots of fibers in the cow feces are effectively decomposed. The organic fertilizer produced by means of animal waste has the advantages that the production means is simple, the fertility is sufficient, the organic fertilizer can be effectively stored for a long term and is applicable to crop rotation.

Description

technical field [0001] The invention relates to the technical field of agricultural production of organic fertilizers, in particular to an organic fertilizer produced by using animal manure and a production method thereof. Background technique [0002] Fertilizers provide crops with the necessary nutrients needed for growth, and also have the function of improving soil fertility and soil properties. The manure excreted by livestock in agricultural breeding is the organic fertilizer often used in traditional agricultural planting. However, there are certain problems in the direct application of animal manure. For example, pig manure is fine in texture and complex in composition, and it is a kind of organic fertilizer with rich fertility. However, the decomposition rate of pig manure is slow, and it is difficult to be used as an effective source of fertilizer in the early stage of decomposition. Cow dung has a large amount of grass leaves, which can provide potassium and oth...

AI Technical Summary

Problems solved by technology

On the one hand, this production method takes a long time. On the other hand, the mixed fertilizer after production cannot be stored for a long time and needs to be used in time.

The above problems have led to the need to calculate the time for farmland cultivation and crop sowing to produce fertilizers for the production of mixed fertilizers.

Not conducive to the efficient and convenient production requirements in modern agriculture
