Experimental Research on Physical Characteristics of Seeds of Polygonatum cyrtonema Hua
摘要
Abstract
In order to obtain the design parameters of Polygonatum cyrtonema Hua seeder,the physical characteristics of P.cyrtonema Hua seeds in Guizhou Province,such as 1 000-grain weight,specific gravity,three-dimensional size,moisture content,seed vigor,sliding friction angle,sliding friction factor and angle of repose,were studied.The results showed that the water content of P.cyrtonema Hua seeds was 34.46%,the average length,width and size were 4.65 mm,4.04 mm and 3.52 mm respectively,the sphericity was 86.95%,the average 1 000-grain mass was 44.98 g,the angle of repose was 26.29,and the sliding friction angles(stainless steel,plexiglass,aluminum alloy and plastic)were 15、13.7、16 and 17.3 respectively,The seed vigor is 97.25%.This study fills the gap in the study of important characteristic parameters of P.cyrtonema Hua seeds and provides theoretical basis for the design of the structure and performance parameters of Polygonatum cyrtonema Hua seeder.关键词
