A new type of equipment for bio-tillage of black soil using earthworm-driven inoculation

Abstract

This invention discloses a novel biological cultivation equipment for black soil using earthworm-driven inoculation. To overcome the lack of existing earthworm complex delivery machinery, this invention designs a new, fully electrically driven, unmanned field delivery system for earthworm complexes. This device solves the problem of material sticking and creating gaps in the material bin by applying high-pressure gas to the bottom of the bin, ensuring a continuous and substantial filling of the material into the feeding mechanism. By using an earthworm feeding box as the main component and assisted by a seeding rate control device, precise delivery is achieved while maintaining a reasonable seeding rate. The seeding spacing can be controlled according to actual needs. These designs not only meet the requirements of smart agricultural machinery but also satisfy the quantitative and non-invasive delivery of earthworm complexes, providing a practical solution to the problems of insufficient soil porosity and soil compaction.

Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and more specifically, this invention relates to a new equipment for biological cultivation of black soil using earthworm-driven inoculation. Background Technology

[0002] Black soil is a precious and rare soil resource on Earth. Against this backdrop, research has revealed that earthworms, driven by food and other factors, can create a macroporous soil structure. Therefore, earthworms were selected as the research subject. Earthworms, along with straw and microorganisms, were introduced into black soil at different distances and in different quantities, allowing the earthworms to survive in the microenvironment and constructing a macroporous soil structure suitable for field crops. This has significant strategic importance. However, currently, there is no agricultural machinery to deliver earthworms, straw, and microorganisms into field soil, let alone specialized equipment for earthworm inoculation under driven conditions. This invention addresses this problem, using earthworm-driven inoculation as a breakthrough to improve the existing black soil environment. It aims to elucidate a macroporous soil structure regulation mechanism, improve earthworm survival rates, and achieve a macroporous soil structure in black soil. This has scientific significance and broad application value. Therefore, inventing a highly reliable new equipment for black soil bio-cultivation under earthworm-driven inoculation is of great importance. Summary of the Invention
