红麻蒴果力学特性试验与分析

Test on the mechanical properties of kenaf capsule

选用福建漳州黄/红麻基地种植的红麻品种,对采集的蒴果进行物理学统计,并对蒴果在顶部与中间位置进行力学特性测试试验。试验表明蒴果在顶部与底部受到压载时,红麻蒴果从中间靠近顶部的位置开始破裂,进而产生裂纹使红麻种子从蒴果中脱出;在蒴果中间位置受到压载时,红麻蒴果从顶端靠近中间的位置开始破裂,进而破裂蒴果;使蒴果破裂的均值挤压力,在顶端位置为240N,在中间位置为130N。

The kenaf varieties of Huang/kenaf base at Zhangzhou,Fujian Province were selected to conduct the physical statistic analysis,and the mechanical properties tests of the capsule at the top and the middle position were carried out.When the top and bottom of the capsule under the ballast,the capsule was broken near the top of the middle position,and thus generated cracks so that the red kenaf seed prolepses.When the capsule in the intermediate position under the ballast,the capsule rupture location was near the middle of the top position,and then ruptured capsule.The mean squeezing pressure at the top position is 240 N,and is 130 Nat the intermediate position.
