Asarum seedlings have weak unearthing ability and strict requirements on soil, so humus soil under the forest is mostly selected as seedling field. Humus soil has the advantages of moist, good structure and strong ventilation, which is suitable for the growth of Asarum seedlings. In general, the emergence rate of seedlings raised on humus soil can reach more than 90%. Asarum seedlings should not choose farmland soil, the physical and chemical properties of farmland soil is not as good as humus soil, easy to harden, seedlings are not easy to be unearthed after sowing, easy to dry bud, even if they come out, the growth is not easy to be strong. The specifications of seedling beds and the requirements for light transmittance are the same as seed fields. Nursery beds should be harvested
