Abstract:
In order to improve the mechanization level of plot-sowing experiment,reduce the labor during the breeding experiment,a kind of plot-sowing precision seeder could be adjust row and seed spacing was designed,with the insert-metering device at its core,which could complete deep-fertilization,precision-sowing,earth-covering and rolling in one circle.According to the standard of JB/T51017-1999 Quality Classification of Precision Seeder for Inter-cultivation Crop,the result indicated that qualified index,repeat-seeding index,miss-seeding index and variable index of the seeder could reach the superior-product standard.According to optimization,the best optimum performance was at the situation that the seed spacing of 7.5 cm and the speed of 3.6 km.h-1.
