Adaptability test of graphite lubricant in nest eye soybean precision seeder
In order to solve problem of seed blockage and jamming in use of a precision seeder for sowing large particle soybean variet-ies such as New Soybean No.26,viewpoint of using graphite lubricant in nest eye seeders was proposed,and its effect on soybean seed germination was explored.Seed germination rate test,angle of repose measurement test,and seeding device seeding test were designed separately to analyze effect of graphite lubricant on soybean sowing.Results showed that graphite lubricant had no effect on soybean ger-mination rate,but had a positive effect on soybean seed angle of repose and sowing amount.The use of graphite lubricant does not af-fect germination rate of soybeans,but can increase seed flowability and effectively reduce hole rate of soybean sowing.It could provide theoretical basis and technical support for use of soybean seeders and improvement of sowing efficiency.
