Gentiana loureiri introduction and cultivation method and substrate

Abstract

The invention discloses a gentiana loureiri introduction and cultivation method and a substrate. Through preserving an ungerminated gentiana loureiri seed, the germination percentage (achieve more than 82 percent) and the emergence rate of the seed are ensured; through adjusting the seeding time and the seeding method, the emergence rate and the survival rate of gentiana loureiri are improved; and through carrying out introduction and cultivation in a country of origin with the altitude of 100-300 m by utilizing the self-prepared substrate, the introduction survival rate and the growth rate of the gentiana loureiri are effectively improved. By applying the gentiana loureiri introduction and cultivation method and the substrate, the gentiana loureiri is introduced and cultivated in a drilling field, so that the scale planting is realized, the resource amount of gentiana loureiri plants can be quickly recovered, and the yield and the quality of gentiana loureiri medicinal materials are effectively ensured so as to to provide enough raw materials for new anti-tumor drug development and relevant pharmaceutical enterprises.

Description

technical field [0001] The invention relates to the cultivation of a rare plant of South China gentian, in particular to a method for introducing and cultivating South China gentian and a substrate. Background technique [0002] South China gentian (Gentiana loureiri (G.Don) Gri seb.), also known as Zihuadiding, is a plant of the genus Gentianae in the family Gentianae. It is mainly distributed in Guangdong and Guangxi. It grows on hillside roadsides, barren hillsides and under forests. 300-2300 meters. South China gentian is mainly used for influenza, sore throat, appendicitis, boils and swollen toxins, carbuncle on the back, unknown swollen toxins, and external use to treat poisonous snake bites. It is a common product for Guangdong coast and overseas Chinese. Clearing away heat and detoxification, reducing swelling and dissipating stagnation is superior to northern chrysanthemum. Wu Min et al.’s research on the chemical constituents of South China gentian shows that it ...

AI Technical Summary

Problems solved by technology

However, because South China gentian is still difficult to successfully cultivate artificially, its raw materials mainly come from wild resources, and there have not been other natural products that can replace South China gentian. Bottleneck in the development of new anticancer drugs

At present, the wild resources of gentian in South China are scattered and the biomass is small, and the output of wild resources is far from meeting the production needs. Therefore, it is urgent to conduct systematic research on the introduction and cultivation technology of gentian in South China, and replace wild resources with cultivated resources, so as to protect rare and endangered species. Wild resources provide sufficient raw materials for relevant pharmaceutical companies
