Problems solved by technology

This method is complex in structure and high in cost
In addition, after the organisms grow in a certain closed negative pressure environment for a certain period of time, they will consume a certain amount of oxygen, resulting in a decrease in the oxygen concentration in the negative pressure environment, which will affect the growth of organisms.

Embodiment 1

[0017] In embodiment 1, such as figure 1 , 2 As shown, the present invention includes a culture box 39 and a negative pressure compensating device. Described culture box 39 is used for placing breeding container, can design corresponding cross-sectional area according to demand, culture box 39 upper end openings, negative pressure compensating device lower end opening, the upper end of cultivating box 39 and the lower end of negative pressure compensating device are respectively provided with mutually. The matching thread structure enables a sealed connection between the culture box 39 and the negative pressure compensation device through the thread structure.

[0018] The negative pressure compensating device includes a cylindrical tank body 17 with an open lower end, and the tank body 17 is provided with a partition plate 10 and a piston 7 . The partition 10 is fixed in the middle of the tank body 17 , and divides the inside of the tank body 17 into upper and lower cavitie...

Abstract

The invention discloses a low pressure seed processing apparatus, and belongs to the technical field of biology. The low pressure seed processing apparatus is characterized by comprises a culture boxand a negative pressure compensation device. The negative pressure compensation device comprises a cylindrical tank with an opening in the lower end. A partition plate and a piston are arranged in thetank. The partition plate is fixed on the middle position of the tank and divides the interior of the tank into two cavities: an upper cavity and a lower cavity. The piston is arranged in the upper cavity. The edge of the piston and the inner surface of the tank are connected in an airtight mode. The middle of the piston is provided with a vertical central hole. A piston rod penetrates the central hole. A No.5 spring is arranged between the piston and an upper flange. The periphery of the piston rod is provided with one or more spring pieces. A gas separation film is arranged on the lateral wall of the tank in the lower cavity. The partition plate is provided with a valve body. Compared with the prior art, a low pressure culture environment with a constant oxygen content can be provided.

Description

technical field [0001] The invention relates to a biological cultivation device, in particular to a low-pressure seed treatment device. Background technique [0002] Studies have found that organisms treated with low pressure can produce different growth effects under normal pressure. For example, Cyclocarya paliurus seeds can end their dormancy inhibition after a certain negative pressure treatment and promote seed germination. Lettuce grows under certain low pressure conditions. After a period of adaptation, the growth was more vigorous than that under normal pressure, and the leaf width was also significantly larger than that of lettuce grown under normal pressure. Therefore, devices that can provide a low-pressure environment are often used in biotechnology. In addition, some agricultural or biological scientific research needs to simulate the hypoxic and low pressure conditions on the plateau. [0003] At present, the low-pressure environment is mainly realized by the...
