Aiming at the problem of low seedling rate during maize breeding test and uneven seeding of existing striped seed drainers,optimized the design on the basis of existing striped planter.Increase the homogeneity of the row by adding the homogeneous lattice to the cone.The influence of tilt angle,number of average lattice and speed of the cone on the planting performance of the average format cone was analyzed and simulated.The experimental results show that when the speed of the cone is 0.8 rad/s,the inclination angle of the cone is 48.1°,and the average number of cone cells is 30,the optimal performance of the seed arrangement,the variation coefficient of the homogeneity of the cone arrangement decrea-ses to 20.295%.Field experiments show that the uniformity variation coefficient of the homogeneous vertebral platter is re-duced by 18.73%,and the platting performance of the platter is significantly improved,which can meet the test require-ments of the district.
