Method for planting radix tetrastigme under crown

The invention relates to a method for planting radix tetrastigme under the crown, which is capable of improving yield and selenium content. The method comprises the steps of forest land selection, seedling selection, seedling raising, transplanting, daily management, pest control and harvesting management. In the steps of seedling selection and seedling raising, a cuttage propagation method is adopted, a 3-5-year-old wild radix tetrastigme is excavated from March to June each year, branches with no disease, robust growth and axillary buds are selected, and are cut into scions which have lengthof 10 cm and have two tender axillary bud segments, oblique lower cuts of the scions are wrapped in a greenhouse by a first matrix rich in culture solution, the scions are cultured for 10-15 days, and roots of radix tetrastigme seedlings are dropwise added with a culture solution three times in the morning, at noon and in the evening; then the seedlings are transferred into a second matrix for culturing for 30-40 days; a
