摘　　要：水稻芽种物理特性的试验研究是水稻精量播种装置设计的基础。目前,对水稻种子的物理特性研究较多集中在干基稻种以及包衣丸化后稻种的研究,而对水稻发芽后的物理特性研究甚少。为此,以黑龙江省常见的水稻品种为试验材料,对芽种的三轴尺寸、千粒质量、静止角及自流角进行了测量。试验得出在含水率为23%条件下各品种水稻芽种的三轴尺寸、千粒质量分布范围及芽种的自流角和静止角的分布区间,旨在为今后播种机具的设计提供最为基本的理论参数和依据。Study on the physical properties of rice-bud-seeds is the basis of sowing machine design , Study the physical characteristics of rice seeds Research focuses on the physical characteristics of dry seed and after pelleted rice physical characteristics , and less on the physical characteristics of rice after germination studies .This paper is commonly used rice seed in Heilongjiang province for the trial materials ,For The three dimensions , thousand seed weight , angle of repose and angle of auto-flowing were studied .Experiments in the the distribution of the interval water content was 23%of all varieties of rice seeds The three dimensions , thousand seed weight , angle of repose and angle of auto-flowing ,It will provide the most basic theoretical parameters and the basis for the future design of a seeder .
