Abstract: According to the problem of straw blocking of no-tillage winter wheat planting in corn residue and weed-covered fields in annual double cropping areas of China, this paper put forward an anti-blocking method that the combined opener was adopted embedded with driving disc, and the driving disc anti-blocking unit was designed for no-tillage wheat planter. Furthermore, the key parameters were analyzed and determined. The field experiment showed that the driving disc unit was effective in solving straw blocking and ensuring the passing ability of no-tillage wheat planter. Compared with strip-chopping wheat no-tillage planter, the driving disc no-tillage wheat planter improved the stubble-cutting rate by 11.2% and decreased soil disturbance by 58.8%. Compared with the fields planted by strip-chopping and traditional planters, the fields planted by driving disc no-tillage wheat planter have the highest soil moisture in 0-20 cm depth and the greatest number of tiller and secondary root, indicating this new planter can meet the requirements of agronomy in two-crop a year regions effectively.
