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.

Abstract

The invention discloses a low-pressure seed treatment device, which belongs to the field of biotechnology, and is characterized in that it includes a culture box and a negative pressure compensation device; the negative pressure compensation device includes a cylindrical tank with an open lower end, and a Partition plate and piston; The partition plate is fixed in the middle of the tank body, and the tank body is divided into upper and lower chambers, namely the upper chamber and the lower chamber; the piston is located in the upper chamber, and the periphery of the piston and the tank body The surface is airtightly connected; a vertical central hole is provided in the middle of the piston, and the piston rod passes through the central hole; a No. 5 spring is provided between the piston and the upper flange; one or more a spring piece; a gas separation membrane is provided on the side wall of the tank at the position of the lower chamber; a valve body is provided on the partition. Compared with the prior art, it can provide a stable low-pressure culture environment with constant oxygen content.

Description

Technical field [0001] The present invention relates to a biological culture device, in particular a low-pressure seed treatment apparatus. Background technique [0002] Biological found after the low-pressure process capable of producing different effects of the growth at atmospheric pressure, e.g. paliurus seed after a certain negative pressure treatment capable of inhibiting the end of its sleep promoting seed germination, lettuce grown after a low pressure under certain after a period of time to adapt to the growth more robust than the atmospheric pressure, which is significantly larger than the width of the width of the blade leaf lettuce grown under normal pressure. Therefore, in biological research art device to provide a low pressure environment often used. In addition, agricultural or biological research need to simulate the hypoxic conditions of low pressure plateau. [0003] Currently low pressure environment primarily through the aspirator, barometer detected by the p...
