Abstract
In order to improve wheat seeding uniformity, a 7.5 cm rows-spacing seed-filling groove style precision seed-metering device is designed to replace traditional external groove-wheel seed-metering device. Size and number of seed groove, upper curve of curb plate to transfer seed, upper curve of blocking plate to clear seed and the diameter and width of seed metering wheel parameters are analyzed and computed. Field experiment of the seeder indicates that 7.5 cm row-space seeder seeds more uniformitier compared with the 15 cm row-space seeder in the same seeding amount. Primary and secondary roots number of seedlings of 7.5 cm row-space is relatively large. It had stocky stem and high tillering ability. By estimation yield, the yield of 7.5 cm rows-spacing increases 8.9% more than 15 cm rows-spacing.
