Composite carbon rod structure based on biochar

Abstract

A composite carbon rod structure based on biochar comprises one or more carbon rods, each embedded in a deep hole around a plant. Each carbon rod is a columnar rod with a multi-microporous structure formed from bio-binding mud. The bio-binding mud is a mud composed of multiple biological particles connected by an adhesive. The multiple biological particles are formed by mixing microbial char with starch and the proportion of starch controls the porosity of the multi-microporous structure of the rod. When microbial inoculants are poured onto the carbon rod, the multi-microporous environment of the carbon rod allows the microbial inoculants to grow, multiply, and release nutrients. In addition to the full decomposition of fertilizer, which enables plants to absorb nutrients well and avoids soil hardening or acidification, it also reduces the time and labor required for soil turning and backfilling, and facilitates soil testing and management.

Claims

1. A composite carbon rod structure based on biochar, comprising one or more carbon rods, each embedded in a deep hole drilled around the soil of a plant cultivation base, wherein each carbon rod is a columnar rod with a multi-microporous structure formed from bio-bonded mud; wherein, The bio-bonded mud is a mud composed of multiple biological particles connected by an adhesive; these multiple biological particles are formed by a mixture of microporous biochar and starch, and the porosity of the multi-microporous structure of the rod is controlled and determined by the content ratio of starch in the biological particles.

2. The composite carbon rod structure of the biochar substrate as described in claim 1, wherein, The proportion of starch in the biological particles is controlled by the microporous structure of the rod, which has a porosity of 10 to 40%.

3. The composite carbon rod structure of the biochar substrate as described in claim 1, wherein, The biochar mixed with starch forms a majority of large bioparticles with a particle size of 2 to 4 mm, containing 10 to 20% small bioparticles with a particle size of less than 0.5 mm.

4. The composite carbon rod structure of the biochar substrate as described in claim 1, wherein, The numerous biological particles are connected by an adhesive, which is syrup, to form the biological binder.

5. The composite carbon rod structure of the biochar substrate as described in claim 1, wherein, The bio-binder is molded in a mold into a columnar shape with a circular, polygonal, or other geometric cross-section.
