Method for cultivating vegetables in space environments

Abstract

A method for cultivating vegetables in space environments includes simulating a space station environment according to special environmental conditions of cosmic space such as intense radiation (cosmic rays), micro-gravity, high vacuum, weak magnetic field (alternating magnetic field), vibration-free and sterility, growth habit and fertility characteristics of vegetables on the earth, and natural ecological conditions of the earth; creating water, fertilizer, air, heat and light conditions suitable for plants to grow through artificial control so as to achieve the purpose of production of the vegetables in the space environment. The method for cultivating the vegetables in the space environments is composed of a cultivation cabin greenhouse, suitable environment system control, a dense optical fiber system, temperature and humidity control, a carbon dioxide concentration regulation system, a nutrient solution circulation system and greenhouse external condition monitoring so as to achieve the control on humidity, temperature, carbon dioxide concentration, oxygen, nutrients and light intensity which are needed for plant growth. The method for cultivating the vegetables in the space environment is applicable to the cultivation of plants such as vegetables and flowers in the space environments such as large spacecrafts, international space stations, the moon and the mars as well at to space breeding.

Description

technical field [0001] The invention relates to a cultivation method in a special environment belonging to the field of plant cultivation. The invention is suitable for cultivating vegetables, flowers and other plants in outer space such as large-scale spacecraft, the international space station, the moon, Mars, etc., and can carry out space breeding at the same time. Background technique [0002] The aerospace industry is an emerging industrial sector that human beings develop into space, and it has both military and civilian uses. With the development of aerospace technology, the aerospace industry will enter a new stage of large-scale development and utilization of outer space. In terms of civilian use, various application satellites that directly serve the national economy and people's lives are developing in the direction of high performance and multi-purpose, in order to obtain greater economic and social benefits. [0003] Human beings will use the microgravity, hig...

Problems solved by technology

At present, foreign crop space breeding is still in the research stage, and no practical crop varieties have been bred for large-scale application in production. However, my country has conducted more comprehensive research and application, and space breeding research has reached the world's leading level.
