Technical Field
The invention relates to experimental equipment, in particular to an ecological circle culture method suitable for an extraterrestrial space.
Background
The amount of resources on the earth is huge, but due to the development of society, the absolute amount of population is increased, and the resource development is further expanded, so that the occupation amount of the resources on the earth per capita is reduced year by year.
With the further development of scientific technology, the possibility that human beings face other stars is gradually evolving towards reality, and at the present time that earth resources are gradually lacked due to excessive development, it is a realistic problem to provide scientific research in the present time to research how to utilize star-cultured organisms (animals and plants) other than the earth.
The environment of other stars in the outer space is different from the earth, and is not suitable for the growth and reproduction of the terrestrial organisms, so that an environment needs to be researched, the environment can be used for the outer space and the earth except for the terrestrial organisms to culture the organisms so as to obtain the data of the organisms cultured on the earth except for the terrestrial organisms, and a theoretical basis is provided for utilizing resources on the earth except for the terrestrial organisms.
Therefore, there is a need for an ecosphere cultivation method suitable for extraterrestrial space, which can create and simulate an environment relatively suitable for the growth or cultivation of organisms on extraterrestrial stars, provide conditions for the extraterrestrial space ecological cultivation, and can form an extraterrestrial space ecosphere to ensure the smooth progress of the extraterrestrial space biological experiment process.
