It is an effective way to reduce chemical fertilizer consumption by changing the fertilization method from traditional strip fertilization to applying fertilizer to concentrated growth zone around the roots of the corn plant. A kind of full layer and hole fertilization of corn seeder was designed. The virtual prototype of fertilizer distributor was designed, and the physical engine in Solidworks was used to carry out the motion simulation of the batch fertilizer and the discharge pipe, and optimize the discharging mechanism to make the fertilizer discharge faster and more concentrated, so that the fertilizer can be applied into the soil in 0.15s. LS-DYNA was used to simulate and analyze the falling fertilizer status of intermittent fertilizer mechanism of the layer and hole fertilization system, and the distribution of fertilizer in soil applied by the layered fertilizer pipe, with the MAT147 soil model and smoothed particle hydrodynamics （SPH）algorithm. The simulation results showed that the mechanism can apply fertilizer to the depth from 7cm to 23cm under the surface of soil, and concentrate in a cylindrical space with diameter of 150mm. The amount of fertilizer in this space was increased with the increase of depth, and the quantity was maximum in the deepest layer, it met the practical application requirements of corn plant growth and reduced unnecessary fertilizer waste. Soil bin test and field test were carried out, and the results agreed well with the simulation results. This novel layer hole fertilization can effectively reduce the consumption of chemical fertilizer.
