Suitable rapeseed cultivation techniques of domestic agriculture are essential for stable security, supply and demand of rapeseed. This research developed a rapeseed seeder for bio-diesel and analyzed the seeding performance improving an existent granule fertilizer applicator. The relational expression of metering groove size and discharge rate per time displayed high correlation with a coefficient of determination of 0.988. Also, the scattering types were analyzed by forwarding speed and discharge rate. Validity application width was decided as 7.0 m by analyzing application uniformity at application widths of 7.6 m, 6.6 m, 5.6 m. All average coefficients of variation values were less than 20%. The best application uniformity was obtained in the condition of a work speed of 1.3 m/s and a sowing rate of 19.0 g/s. It was better average coefficient of variation values under 10% at superposition application of rapeseed seeder. Also, scattering amount rates of right and left were within 0.891.0. |
