트랙터 부착용 유채 파종기 개발

초록

Suitable rapeseed cultivation techniques of domestic agriculture are essential for stable security, supply and demand of rapeseed. This research develops rapeseed seeder for Bio-diesel and analyzed the seeding performance improving existent granule fertilizer applicator. The relational expression of metering groove size and discharge rate per time displayed high corelation of coefficient of determination 0.988. Also, the scattering types were analyzed by the forwarding speed and discharge rates. Validity application width was decided 7.0 m by analyzing application uniformity about application width 7.6 m, 6.6 m, 5.6 m. All average coefficient of variation values showed less than 20%. It was the best application uniformity in the condition of work speed 1.3 m/s and sowing rate 19.0 g/s. It was better average coefficient of variation values under 10% at superposition application of rapeseed seeder. Also, Scattering amount rate of right and left was within 0.89~1.0
