| 摘 要： | 水稻芽种物料特性的研究是水稻芽播机设计的基础.当今对水稻芽种物料特性的研究很少。本文以湖南省常用的水稻品种为试验材料,对芽种的三轴尺寸、休止角和滑动摩擦角进行了测量。试验得出：芽种的三轴尺寸为长度在8-10mm,宽度在2.5-3.5mm,厚度在2.2mm左右;含水率相差不大的不同品种的水稻芽种的休止角和滑动摩擦角有一定差别,而同品种不同含水率下的休止角和滑动摩擦角差别比较大,随着含水率的减小休止角也相应的减小。

| Abstract: | Study on the material-properities of rice-bud-seeds is the basis of sowing machine design, but the study of the material-properities for rice-bud-seeds is very few now. This paper is commonly used Hybrid rice seed in Hunan for the trial materials, the rice-bud-seeds of the three-axis size, stop-angle and gliding friction angle was measured. |
