The invention relates to the cultivation technical field and particularly discloses a method for improving Ginseng land through coal cinders. The method comprises step 1, performing once rotary tillage on old Ginseng land according to the 30 cm of depth, removing impurities and raking and step 2, uniformly laying the 10 to 40 meshes of granularity of coal cinders after crushing on the raked Ginseng land after the once rotary tillage and weed and impurity removal according to the 2 to 18 kg of use level, performing three times of repeated rotary tillage according to the 30 cm of depth to enable the uniform rotary tillage to be performed on the coal cinders and the old Ginseng land soil, producing a Ginseng bed according to the 30 cm of height and raking the ridge surface to be fine and smooth through a rake to obtain the coal cinder improvement Ginseng land. According to the method for improving the Ginseng land through the coal cinders, the emergence rate and the survival rate of seedlings of Ginseng and American Ginseng are significantly improved, the growth and the Ginseng monomer saponin accumulation are promoted, and the problem of continuous cropping obstacles of the Ginseng, the American Ginseng and other plants of the old Ginseng land can be effectively solved.
