Problems solved by technology

Large-scale pharmaceutical production using wild warmland moss will face many problems: First, the natural growth process is often affected by changes in the natural environment, and there will be various mutated individuals or groups, which will affect the consistency and consistency of resource yield and resource traits. stability; secondly, different harvest periods and different origins will affect the stability of the quality of medicinal materials; more importantly, the distribution of wild plant resources in nature is scattered, and there is almost no phenomenon of large-scale flakes. Wild plants have become an important resource for development. On the one hand, it is difficult to meet the needs of the market by relying on wild resources alone. On the other hand, under the pressure of development and utilization, they are easily destroyed and pose a direct threat to the survival of species.
However, in the prior art, there is no culture technique for a large number of gametophytes in test tubes of Physcomitrella plants, and there is no relevant technical report on culturing the Physcomitrella plant tissue into gametophytes.

Abstract

The invention discloses a method of manual extensive-reproduction of rhodobryum giganteum gametocyte, which includes steps in the following order: (1) sterilizing the surface of the rhodobryum giganteum gametocyte which grows in a natural environment with unexpanded leaf blades; cutting the stem tip and inoculating to the culture medium of inducing the gametocyte to generate the protonema and culturing for 40-60 days; (2) transplanting the protonema obtained in step (1) to the extensive-reproduction protonema culture medium and culturing for 40-60 days; (3) transplanting the extensive reproduced protonema in step (2) to the culture medium of inducing the protonema to generate the gametocyte and culturing for 40-60 days. The invention initiates the development of the method of manual extensive-reproduction of rhodobryum giganteum gametocyte and bridges the gap of the prior art. The manual extensive reproduction not only greatly facilitates the production of high intensification and high density industrialization, but also facilitates automatization of production control; which achieves the mass production of manual extensive-reproduction of rhodobryum giganteum in a short time and provides a market guarantee for the pharmacy field with significant economic benefits.
