The invention provides a method for cultivating radix notoginseng in a bamboo stand. The method comprises the steps of bamboo stand selection, bamboo stand clearing, radix notoginseng seed treatment and seedling culture, planting, field management and harvesting. According to the method, the slope of the bamboo stand for radix notoginseng cultivation is 5-25 degrees, bamboo plantation density is controlled to be 15-200 pieces per mu, bamboo shoots are harvested in spring based on the principle of reserving the sparse and big and controlling the dense and small, 15-20 new bamboos are left, a sound radix notoginseng growth environment is guaranteed, the quality of radix notoginseng is improved, and green ecological organic radix notoginseng is cultivated; by cultivating radix notoginseng under a bamboo forest, forest land resources can be sufficiently utilized, farmland is not used, and radix notoginseng cultivation space is enlarged; meanwhile, radix notoginseng can be shaded by the bamboo forest, a good natural environment is provided, sun shelter building is not needed, and production cost is reduced greatly; besides, there is no weed under the bamboo forest, manual weeding is not needed, and therefore production cost can be further reduced.
