Based on the agronomic characteristics of yearly maize-wheat rotation in Huanghuaihai Plain, a new-concept no-till planter, named 2BMDF-8 no-till wheat-maize planter, has been developed by Shandong University of Technology to solve an extremely important problem, such as standing maize stubble in one pass in two-crop rotation areas of Shandong Province in China. The combine anti-blocking device that is composed of power chopping axle and the planting unit of double-disc opener was designed. The test results of field performance showed that the machine could accomplish many working procedures, such as stubble chopping, furrow opening, seeds and fertilizer placement etc, in one pass, so the operation cost could be decreased by about 30%. The machine worked well for planting wheat into fields with standing maize stubble and maize stubble shattered. The powered chopping axle resolved the anti-blockage problem that ahead of shank the double-disc opener unit reduced the blockage between planting units. Meanwhile the variations in seed depth reduced to 18.8% and 19.3% respectively. Therefore, this machine will be a good solution to no-till wheat-maize planting in two crop rotation areas.
