Outer-space plant culturing column and special outer-space planting system provided with the same

Abstract

The invention discloses an outer-space plant culturing column and a special outer-space planting system provided with the same, and belongs to the technical field of soilless culturing. The outer-space plant culturing column and the special outer-space planting system aim at solving the problem that the long-term requirement of spacemen for fresh vegetables and the oxygen supply requirement of the spacemen can not be met during existing outer space traveling. A central drip irrigation pipe, a one-way permeating lining, a root system growing layer, a water partition film, a honeycomb-shaped supporting net and a planting layer are sequentially connected from inside to outside to form a cylinder. A water inlet pipe and a water delivery pipe are both arranged in an inner cavity of the central drip irrigation pipe. A water inlet control valve is installed at the upper end of the water inlet pipe. A soil humidity sensor is located inside the outer-space plant culturing column. A top filtering layer is arranged on a first tray, a bottom filtering layer is arranged on a second tray, a nutrition blending tank is located on the top filtering layer and communicated with one end of a nutrition detection device, the other end of the nutrition detection device extends into the water delivery pipe, and a bottom water pump and a top water pump are located below the bottom filtering layer and above the top filtering layer respectively. The outer-space plant culturing column and the special outer-space planting system are used for outer-space vegetable soilless culturing.

Description

technical field [0001] The invention relates to a space plant cultivation column and a space-specific planting system equipped with the cultivation column, belonging to the technical field of soilless cultivation. Background technique [0002] Although the types of aerospace food are becoming more and more abundant, they are still mainly dry food, rehydrated food, canned food, etc., which are generally high in calories and can be stored for a long time. The fresh fruits and vegetables that can be carried are very limited, because every kilogram Food to the International Space Station costs nearly £14,000. Planting ingredients in space will solve the problem of supplying fresh ingredients in future long-distance space travel, and can reduce the cost of transporting food. [0003] The transportation cost of conventional soil planting is high, and it is not convenient for watering, and it is easy to bring pollution to space. It also requires people with certain professional s...

Problems solved by technology

[0003] The transportation cost of conventional soil planting soil is high, and it is not convenient for watering, and it is easy to pollute the space

It also requires people with certain professional skills to plant and manage, which consumes time and energy

Although it has been reported that vegetables can be grown in space, it is only on an experimental scale, and it is difficult to meet the long-term needs of astronauts for fresh vegetables and oxygen supply requirements. At present, they are generally planted on a flat surface, which wastes space and lacks ornamental features.
