Endangered plant sphaeropteris lepifera propagation technology and field regression method

Abstract

The invention relates to an endangered plant sphaeropteris lepifera propagation technology and a field regression method. The technical problems that spore propagation of sphaeropteris lepifera is difficult, and the requirements of spores for matrix water-retaining property, air permeability and nutrient supply are harsh are solved. A disinfection scheme is continuously optimized for a long time, meanwhile, a culture medium is changed, sterile filter paper is explored to be placed in a culture dish, the growth conditions of the spores of the sphaeropteris lepifera are regulated and controlled, and the breeding effect of accelerating the spores to the gametophyte period is achieved. Meanwhile, through precise control after transplanting and matching with special equipment, a stable breeding system of the sphaeropteris lepifera is formed, and the technical problem of sphaeropteris lepifera breeding is effectively solved.

Description

technical field [0001] The application relates to the field of plant protection, in particular to a breeding method and special equipment applied to the endangered plant pen holder tree. Background technique [0002] Endangered plants refer to plants that are facing the crisis of extinction due to changes in the environment. According to plant researchers, the extinction of species and the formation of new species are a natural evolutionary process. Due to changes in the earth's environment, some species cannot adapt to the new environment. While extinct, some new species adapting to the new environment are formed at the same time. The survival of plants, as an indispensable link in biodiversity and ecosystems, has been subject to the pressure of internal and external troubles, and a large number of plants are going to be endangered silently. The reasons for the endangerment of plants are very complex, but external factors such as improper human activities, climate change an...

AI Technical Summary

Problems solved by technology

This method undergoes long-term tissue culture, and explant disinfection can easily pollute the pen holder tree and affect its vitality. The survival rate of this culture method is low, and it is impossible to form a large number of propagation systems.

In fact, we found that the tissue culture and reproduction of the leaves of the pen container tree and other parts of the leaves encountered bottlenecks, serious pollution, and the problem of long-term "pollution" cannot be overcome, and it is not easy to form a stable culture system

[0006] At the same time, the growth of the pen container tree after transplanting is also greatly affected by the environment. Too high or too low temperature will affect its growth. At present, only the breeding method of the pen container tree has been studied. There is a lack of comprehensive and systematic research on the measures applicable to the protection of endangered plants
