Plant cultivation system under environmental condition of controlled ecological life support system

Abstract

The invention relates to a plant cultivation system, especially a plant cultivation system for an integrated test platform of a controlled ecological life support system under long-term manned flight space environmental conditions such as spaceports, extraterrestrial spacecrafts and planet bases. The plant cultivation system comprises a condensate water storage tank, a submersible pump, a control unit assembly, an acid liquid storage tank, an alkali liquid storage tank, a mother solution A storage tank, a mother solution B storage tank, a mother solution C storage tank, a four-channel peristaltic pump, a single-channel peristaltic pump, a nutrient solution storage tank, a sensor assembly, a centrifugal pump, a manual adjusting valve assembly, an illumination system, a plant cultivation bed assembly, a nutrient solution collection tank and the like. Under the monitoring control of the control unit assembly, the preparation of the nutrient solution required for cultivating the plant is finished in the condensate water storage tank, the acid liquid storage tank, the alkali liquid storage tank, the mother solution A storage tank, the mother solution B storage tank and the mother solution C storage tank. The nutrient solution storage tank, the centrifugal pump, the manual adjusting valve assembly, the illuminating system, the plant cultivation bed assembly, the nutrient solution collection tank and the centrifugal pump form a nutrient solution delivering pipeline for the cultivation plant. The plant cultivation system disclosed by the invention is not only suitable for a controlled ecological life support technical test platform, but also can be used for providing a new technical path for high-efficiency intensive agricultural production.

Description

technical field [0001] The invention relates to a plant cultivation system, in particular to a research field of environmental control and life protection technology for long-term manned spaceflight, in particular to plants under manned space conditions such as space stations, extraterrestrial spacecraft, and planetary bases. cultivation system. Background technique [0002] Judging from the current development level of aerospace technology, it is not impossible for human beings to land on extraterrestrial planets such as the moon or Mars, but the key problem is that they cannot stay for a long time. One of the important bottlenecks is the lack of basic conditions for the survival of the crew---food , continuous supply of oxygen and water. The fundamental way to solve this problem is to establish a corresponding long-term manned spaceflight life support system - controlled ecological life support system. [0003] The controlled ecological life support system is based on bi...
