High-pressure cultivation system

Abstract

The invention relates to a high pressure cultivation system, in particular to the high pressure cultivation system keeping an atmospheric pressure environment higher than the standard atmospheric pressure in a cultivation chamber and having a certain amount of air circulation quantity. The system comprises an airtight cultivation chamber which is communicated with a high pressure air source through an air inlet duct; and an air flow controller and an air valve are arranged between the high pressure air source and the air inlet duct. The cultivation chamber is also communicated with a plurality of pressure control pipes through an air outlet duct; the liquid for controlling the atmospheric pressure inside the cultivation chamber is injected in the pressure control pipes; and the level altitude of the injected liquid in the pressure control pipes is lower than that of the air outlet duct. The system can not only keep the constant atmospheric pressure higher than the standard atmospheric pressure inside the cultivation chamber, but also make the air in the cultivation chamber circulate continuously in a constant flow quantity and control the direction of the air flow in the cultivation chamber.

Description

technical field [0001] The invention relates to a greenhouse cultivation system, in particular to a high-pressure cultivation system for maintaining an air pressure environment higher than standard atmospheric pressure and a certain air circulation flow in a cultivation chamber. Background technique [0002] Dust-free bacteria cultivation can significantly improve the safety and quality of crop products, and increasing the pressure value of the plant cultivation environment can significantly inhibit the entry of external germs and pests, reduce the occurrence of germs, diseases and pests in the plant production process, and have a greater change in plant productivity potential.

Problems solved by technology

At present, there are many ways to control the gas pressure in a closed container, most of which are monitored by electronic instruments, and the air pressure in the container is maintained by using an air blowing pump or an air compressor. When the air pressure in the container reaches the set pressure value, the air blowing pump or air The compressor stops working, so that the air pressure in the container can be effectively controlled, but with this method, the air pressure value in the container may be a changing process, and the gas in the container does not form a circulating flow, even if the container is set out Gas port, the air pressure value is also difficult to adjust and maintain at a constant level, which makes it difficult to maintain a constant air pressure and a certain flow of gas circulation in the container at the same time
