摘      要：The technology used for the storage and transportation of Artemisia selengensis is becoming increasingly important with its increasing consumption and demand;moreover,the amounts of artificial planting contribute to the challenges in Artemisia selengensis ***,the mechanical property parameters of the Artemisia selengensis stalks were determined and researched to reduce the mechanical damage during harvesting,transportation,processing and *** Artemisia selengensis stalks were taken as the test object and a physical test method was adopted to study the impact of different positions,diameters,and directions on the mechanical properties by using the TMS-Pro texture analyzer;then,the relevant changing trends of the characteristic mechanical parameters were analyzed using statistical *** the compression test,the compression load-deformation curve was observed and the breaking force and deformation were obtained;then,the compressive strength,elastic modulus and compression energy were ***,the curve-fitting of the compressive strength and compression energy was carried *** the shear test,the shear stress-deformation curve was obtained and the shear force,deformation,shear strength,and shear work were ***,the regression fitting of the section area,peak shearing stress and shearing work was ***,in the last bending test,the bending stress-deformation curve,bending peak force,deformation,and bending work were *** the bending forces of other plants were tested,the results were compared and analyzed with the theoretical values,and finally the regression fittings were *** the analysis results showed that Artemisia selengensis stalks can be considered to be anisotropic *** results also showed that the compressive strength and elastic modulus decreased with the height of stalk position,while the deformation *** addition,with the increase in the stalk diameter,the bending
