Production system and production method of carbon-based organic-inorganic compound fertilizer

Abstract

The invention belongs to the technical field of agricultural resource, and particularly relates to a production system and a production method of a carbon-based organic-inorganic compound fertilizer,wherein the production system comprises a pretreatment device, a carbonization furnace, an oil-gas separation system, an oil-water separation system, a fermentation system, a drying and crushing system, a mixing granulation system and a steam boiler system. According to the present invention, the oil-gas resources generated in the carbonization process are recovered and utilized, and the biochar produced by pyrolysis and the chemical fertilizer are combined to produce the carbon-based organic-inorganic compound fertilizer, such that the returning of the agriculture and forestry biomass straw to the soil is achieved, the organic matter of the soil is increased, the adsorption performance of biochar is utilized, and the slow release of chemical fertilizer nutrients is achieved so as to improve the utilization efficiency of chemical fertilizers.

Description

technical field [0001] The invention belongs to the technical field of agricultural resource utilization, and in particular relates to a production system and method of carbon-based organic-inorganic compound fertilizer. Background technique [0002] At present, the fertilizers used in agriculture are mainly divided into chemical fertilizers and organic fertilizers, but with the improvement of living standards, the cultivation of crops is becoming more and more simple and mechanized. Fertilizers containing one or several nutrient elements needed for the growth of crops, long-term use will easily lead to the destruction of soil structure, reduced production potential, increased metals and toxic elements, reduced microbial activity, difficult conversion and degradation of substances, and nutrient imbalance , Accumulation of nitrate, intensified acidification, too much pH change and other problems. Among the organic fertilizers, most of them are farmyard manures. Although they...

AI Technical Summary

Problems solved by technology

At present, the traditional chemical fertilizers on the market contain less nutrients, which cannot fully meet the needs of crop growth, and the price is high, and the effect of increasing production is not obvious. In addition, there are problems such as low fertilizer utilization rate and excessive application amount.
