Abstract

The invention provides a method for harvesting branches and leaves of Taxus yunnanensis. During harvesting, the shrubs and grasses under the yew tree are cleared, position marks are made on the main trunk at the position of 1 / 2±10cm of the height of the crown, and the crown above the position mark Harvest all the branches and leaves, keep only the trunk, spray the copper sulfate solution with a mass concentration of 2 to 5% on the wounds of the harvested branches for disinfection treatment, and apply a protective agent after the solution is dry; or apply protection directly to the wound. According to the routine tree management of the harvested Taxus yunnanensis plants to promote the regeneration of branches and leaves, until they grow for 2 to 3 years, they will be harvested repeatedly. Utilizing the method can ensure that both the harvesting amount and the regrowth amount reach the maximum, and has the characteristics of low cost, simple operation, easy grasp of the method, large profit and the like.

Description

technical field [0001] The invention relates to a method for harvesting medicinal raw material forests, in particular to a method for harvesting branches and leaves of Yunnan yew medicinal raw material forests, and belongs to the technical field of forest management. Background technique [0002] Taxol (Taxol) is Taxus ( Taxus ) plant-specific secondary metabolites, due to its unique anti-cancer properties, it has become a broad-spectrum natural anti-cancer drug with high efficiency and low toxicity, and has been used in more than 40 countries for ovarian cancer, metastatic breast cancer, and non-small cell lung cancer and Kaposi's sarcoma and other cancer treatment. Taxus yunnanensis is the species with the highest paclitaxel content in the genus Taxus. Therefore, yew yunnanensis has extremely high medicinal value and economic value. However, due to the weak competitiveness of Taxus yunnanensis populations, slow natural regeneration, limited geographical distribution, and...
