Abstract

The invention discloses a preparation method of organic agricultural biochar-based fertilizer. The preparation method specifically comprises the following steps: (1) preparing raw materials for preparing the organic agricultural biochar-based fertilizer, (2) drying the human and animal excreta in drying equipment, crushing the human and animal excreta into particles, and sieving the particles, (3)adding the charcoal particles and human and animal excreta into a stirring kettle to form a mixture, (4) adding a microbial agent for fermentation,(5) drying the fermented mixture, (6) adding corresponding parts by weight of other components into the fermented mixture, then adding the mixture into a granulator for granulation, cooling, sieving and drying to obtain the organic agricultural biochar-based fertilizer, and (7) packaging the dried organic agricultural biochar-based fertilizer. The invention relates to the technical field of agricultural solid waste treatment and resource utilization, and particularly provides the preparation method of the organic agricultural biochar-based fertilizer which is environmentally friendly, high in fertility and efficient and rapid in preparation.

Description

technical field [0001] The invention relates to the technical field of agricultural solid waste treatment and resource utilization, in particular to a preparation method of organic agricultural biochar-based fertilizer. Background technique [0002] Soil is composed of minerals, organic matter and soil microorganisms. Microorganisms play an important role in the occurrence and development of soil, such as decomposing organic matter and minerals, fixing nitrogen, etc. The life activities of microorganisms in the soil are based on soil organic matter, transforming soil nutrients, improving soil fertility, and providing nutrients for plant growth and development. In turn, the improvement of soil fertility can promote the reproduction of microorganisms. In recent years, with the large-scale application of chemical fertilizers, although the yield of crops can be increased in a certain period of time and to a certain extent, it has caused such as a sharp decrease in soil organic...
