AI Technical Summary

Technical Problem

Existing gas collection devices cannot create a stable dark environment in microcosms such as moss, resulting in the collected gas containing a combination of products of photosynthesis and respiration, which affects the accuracy of data and the reliability of research results. In addition, the complex structure and cumbersome operation of the devices reduce collection efficiency.

Method used

A collection hood composed of concentric transparent cylinders was designed. The inner cylinder serves as a gas flow channel and is equipped with a lifting ring and a light-shielding cloth. By switching the lifting state of the light-shielding cloth, flexible simulation of light and dark environments can be achieved. Combined with a transmission system of screw, motor and positioning rod, the stability and ease of operation of the device are ensured.

Benefits of technology

This technology enables precise collection of gases emitted by moss respiration under different light conditions, improving the accuracy and efficiency of data collection, simplifying the operation process, and reducing the workload of researchers.
