深根茎类药材机械化收获技术与装备发展现状OA

The economic value generated by the cultivation of deep-root and rhizome Chinese medicinal herbs such as licorice and astragalus has become one of the important ways for many provinces in China to improve regional economic levels and increase farmers'income.However,at present,the mechanization level of harvesting deep root and rhizome medicinal materials in China is relatively backward,facing many problems and challenges.This article first outlines the current development status of mechanization in the harvesting of deep-root and rhizome medicinal materials.Through literature review and technical evaluation,a comprehensive analysis of the development status of relevant harvesting machines and the research progress of key structures of harvesting machines in China is conducted.It is found that there are prominent problems in the current harvesting of deep root and rhizome medicinal materials,including technological lag,limited research and development progress,obstacles to the integration of agricultural machinery and agronomy,poor reliability of mechanical equipment,high mechanical harvesting loss rate,high power consumption,low energy efficiency,and low harvesting efficiency.To address these issues,this article proposes a series of targeted countermeasures and suggestions,including developing combined harvesters,promoting the integration of agricultural machinery and agronomy,applying intelligent regulation technology,strengthening interdisciplinary cooperation and cross-industry technology reference,improving the universality and structural reliability of harvesting equipment,and increasing policy support and machine purchase subsidies.It can provide reference for the mechanized development of deep rooted medicinal herbs in China.
