油用牡丹茎秆穿刺力学特性试验研究
Experimental Study on Puncture Mechanical Property of Oil Peony Stem
摘要
Abstract
The puncture mechanical property of oil peony stem was studied to provide a basis for the efficient harvest of the pod of oil peony.The oil peony of Fengdanbai variety in Luoyang was picked as the research object,the mechanical strength of oil peony stem was measured by the texture analyzer.The physical characteristic parameters such as stem puncture force,diameter and relative moisture content,as well as the content of chemical components such as cellulose,hemicellulose and lignin were analyzed.Then,the puncture force was used as an experimental index to explore the effects of puncture position,relative moisture content and puncture speed on the puncture force of stem.The results showed that the puncture force of stem increased significantly with the increased of stem diameter.With the increased of relative mois-ture content,the puncture force decreased gradually.Besides,there was a positive correlation between puncture force and puncture speed.In the chemical components of stem,the average value of lignin content was the highest(24.980%),followed by cellulose content(17.269%),and finally hemicellulose content(16.935%).The relative moisture content had a significant effect on the puncture force,but the puncture position and puncture speed have no significant effect with the puncture force.The research results could provide a reference for the study of puncture mechanical properties of oil peony stem.关键词
