The invention relates to a bag cultivation method for interplanting radix tetrastigme in fruit-bearing forest land in a bionic mode. The method includes the steps of site selection, digging of planting furrows, manufacturing of special radix tetrastigme cultivation bags, processing of special radix tetrastigme cultivation media, bagging of the special radix tetrastigme cultivation media, planting of radix tetrastigme seedlings, placement of the cultivation bags, cultivation management, harvesting and the like. Radix tetrastigme is planted in the fruit-bearing forest land in the bionic mode through the special radix tetrastigme cultivation bags and the special radix tetrastigme cultivation media. The method achieves bionic cultivation directly due to the nature climatic conditions of the fruit-bearing forest land, is low in cost and easy to implement, the situation that as facilities such as greenhouses and pots are excessively adopted for cultivation, the quality of radix tetrastigme is reduced can be avoided, root tubers are prevented from being damaged in the digging process, and the problem of crop rotation obstacles is solved. The radix tetrastigme bag cultivation method does not conflict with growth of fruit trees, no greenhouse or tillage is needed, radix tetrastigme medical root tubers approaching to wild root tubers are planted out by full utilization of superior nature growth conditions of the fruit-bearing forest land, the quality is good, and yield is high.
