由于免耕播种地表有残茬、秸秆和杂草覆盖，土壤坚硬，免耕播种机的仿形量较大，普通的仿形机构已不能满足仿形的平稳性要求。为此，采用液压式加载仿形深度控制系统，实现玉米垄作免耕播种机下压力和仿形量的调节，保证了玉米垄作免耕播种的播种深度和机器稳定性，克服了目前免耕播种作业的缺点，满足了免耕播种作业质量要求。

Because of residues、roots and hard soil over the field , complex profile modeling ,normal profile modeling was dissatisfied with stable requirements of profiling .This paper designed a hydraulic control system to control sowing depth , adjust to down pressure and profile modeling .The system could get rid of disadvantages of current no-till planter opera-tion, control sowing depth and operation stability , and meet the operation requirements of no-till planting .
