Space plant culture device

Abstract

The invention provides a space plant culture device comprising a culture box which is partitioned into a left chamber and a right chamber via a longitudinal partition. The left chamber is provided with an upper layer and a lower layer, an azolla moist cultivation tray is arranged on the upper layer, a vegetable moist cultivation tray is arranged on the lower layer, the right chamber is provided with a seedling cultivation tray, an LED lamp panel is arranged above the azolla moist cultivation tray, the vegetable moist cultivation tray and the seedling cultivation tray, and the right chamber is further provided with a bag-type solution collecting box used for providing a culture solution and a peristaltic pump used for driving the culture solution to flow. The space plant culture device is provided with a plant culture solution supply system, an LED illumination system and a monitoring system which are complete and needed for growth of azolla and short small salad vegetables in the whole growth period, on-line parameter setting, automatic record storing and intelligent system controlling can be realized, population, individual photosynthetic efficiency and biological-yield efficient production cycle of the plants as well as change rules in space microgravity environment of the plants can be researched, and requirements on spatial scientific experiments and space station key technology experiments can be met.

Description

technical field [0001] The invention relates to a space plant cultivation device. Background technique [0002] The Controlled Ecological Life Support System (CELSS for short) is an advanced system that humans can rely on for long-term, long-distance, multi-crew manned spaceflight activities in the future. Cultivating plants on the space station is the premise of carrying out the research of the CELSS system, and it is also the key research field of various countries on the space station in recent years. In the entire existing manned cabin, astronauts can only eat compressed food all day long, and cannot eat fresh food, which seriously affects the physical and mental health of astronauts in microgravity, and also affects their long-term stay on the space station in the future. Therefore, it is imperative to introduce green plants in the flight cabin. It can not only absorb the CO2 produced by the astronauts’ respiration and release O2, but also harvest fresh vegetables for ...

AI Technical Summary

Problems solved by technology

[0004] The present invention improves the problem that the existing space plant cultivation device has a short cultivation time and cannot adapt to the cultivation of plants throughout the growth period. The present invention adopts a plant wet cultivation method and configures a closed culture solution perfusion supply system to realize the long-term cultivation of small plants. required growth monitoring and integrated environmental monitoring functions, designed to be applied to in-orbit flight tests
