In order to solve the problems of large longitudinal dimension and poor stratification effect of no–till planter separated layer fertilizer furrow opener, a control position separated layer fertilizer furrow opener is designed by consisting of main opener and shallow tail tube. The horizontal position of fertilization was controlled by adjusting the position of the shallow tail pipe position A discrete element model has been built by EDEM to simulate the process of cutting soil furrowing and separated layer fertilizing. The theoretical analysis and simulation results of the soil tillage resistance of the open and lateral fertilizers showed that the lateral fertilizers used in the open ditches had relatively higher soil tillage loadings and smaller load fluctuations. The simulation analysis of stratification and fertilization efficiency of opener was carried out. The results showed that lateral fertilizer application had better stratification effect of fertilizer and more concentrated particle spatial distribution. Field test results show that the control stratum fertilization opener can achieve the function of stratified fertilization, The mean of fertilization depth difference and coefficient of variation of fertilization depth difference of lateral position mode and normal position mode is 4.7 cm, 3.9 cm and 5.1%, 10.8%, and lateral position has a more conspicuous and stable layered performance. The field test results were in agreement with the simulation results.
