The invention provides a sealwort forest lower half wild efficient cultivation technology. The sealwort forest lower half wild efficient cultivation technology comprises the following steps that S1, a forest land is selected, wherein the forest land is selected, wherein the forest land is provided with loam, ventilation, light transmission, yellow soil or red soil with the PH value ranging from 6.5 to 7.5 and the slope ranging from 25 degrees to 40 degrees or is provided with a gentle zone, wherein the loam is in a moist and shaded environment, the soil layer is deep, loose and fertile, and the drainage and water retention performance is good; s2, selection and treatment of seed stems: selecting robust polygonatum rhizome which is moist yellow in color, free of plant diseases and insect pests, free of broken skin and provided with a terminal bud for planting, cutting a tip tender part into a plurality of sections, cutting each section into two sections, having 1-3 bud eyes and being about 50g in weight, dipping or soaking a cut by using a liquid medicine, and planting after airing and slurry collection. By means of the cultivation method, dry branches and fallen leaves and animal and plant bodies provide enough nutrients for growth of the polygonatum sibiricum every year, labor and management and protection work such as fertilization, frame building and weeding are reduced, seedlings and seeds are bred, high efficiency and sustainability are achieved, and the total cost is reduced.
