Space Plant Cultivation Device

Abstract

The invention provides a plant cultivation device in space, comprising an incubator, the incubator is divided by a longitudinal partition to form two chambers on the left and right, the left chamber is provided with upper and lower layers, and the upper layer is provided with a moist cultivation tray for red duckweed, The lower layer is provided with a vegetable moist cultivation tray, and the right chamber is provided with a seedling cultivation tray, a red duckweed cultivation tray, and a vegetable moist cultivation tray. An LED light board is provided above the seedling cultivation tray, and the right chamber is also provided with a Provide a bladder-type liquid collection tank for plant culture fluid and a peristaltic pump for driving the flow of culture fluid, invent a plant culture fluid supply system and LED lighting system and Its monitoring system can set online parameters, automatically store and record, and intelligently control the system. It can meet the needs of space science experiments for the study of these plant groups, individual photosynthetic efficiency, and high-efficiency production cycle of biomass and their changes in space microgravity environments. And the needs of key technology experiments on the space station.

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
