Continuous production test device of fresh plant food under simulated space microgravity effect

Abstract

The invention discloses a test device for realizing continuous production of fresh plant food under the simulated space microgravity effect, and mainly aims to make a research on the problem of supplying the fresh plant food to astronauts in a long-time and long-distance deep space manned spacecraft (such as a Mars landing spacecraft). The device consists of a trumpet-shaped variable-diameter light shade, a mobile circular planting module, a nutrient solution supplying pipeline and a power rotary unit. By using the device, the test research on high-efficiency continuous growth of different types of fresh plant food (such as leaf vegetables, root-stem vegetables and solanaceous vegetables) under the simulated space microgravity effect can be performed, and the test basis is provided for solving the problems of supplying the fresh plant food to the astronauts and making the astronauts physically and mentally healthy in the deep space manned spacecraft.

Description

technical field [0001] The invention relates to an experimental device for continuous production of fresh vegetable food under the effect of simulated space microgravity, which is mainly used to explore and study the continuous supply of fresh vegetable food in a long-term, long-distance deep-space manned exploration spacecraft. The microgravity effect is suitable for the cultivation of various plant foods, and the structure is simple. Background technique [0002] With the development of aviation life support technology, people are more and more aware of the importance of fresh plant food for astronauts in deep space exploration spacecraft. Fresh plant-based food can not only provide visual and psychological comfort to astronauts in a limited space, but more importantly, it can also provide astronauts with fresh green vitamins and biologically active substances to meet their physiological needs and reduce or avoid taking synthetic vitamins potential danger. The aerospace ...

AI Technical Summary

Problems solved by technology

Due to the gravity of the earth, it is necessary to simulate the microgravity effect of the space environment through rotation in the study of space-oriented fresh plant food supply devices under ground conditions. Most of the current plant cultivation rotation devices are based on scientific research, in order to study the effect of microgravity on plant growth. It was established based on the influence of development and genetic variation, and did not take into account the continuous needs of astronauts for fresh plant food, so continuous production cannot be achieved

Although some ground rotary plant cultivation devices can achieve continuous production, they can only be used for the cultivation of a few types of leafy vegetables, and cannot cultivate a large number of other types (such as nightshades, rhizomes) candidate plants suitable for space cultivation.
