[0002] The continuous labeling monitoring device for plant carbon isotopes is mainly used to study and monitor the absorption, assimilation and conversion of carbon during plant respiration. The device can provide real-time and continuous data to help understand the response of plants to environmental changes and their role in the carbon cycle. By introducing labeled carbon isotopes, it is possible to track how plants absorb and utilize carbon from different sources. By measuring the respiration rate of plants and monitoring the changes in carbon dioxide concentration around the plants, the net carbon absorption of the plants is calculated, providing data support for understanding the carbon balance of the ecosystem, providing important data for ecology, plant physiology and climate change research, and helping to understand the important role of plants in the carbon cycle.

The transparent sealed box comprises an inlet, an air inlet, and a drain outlet; the 13CO2 generation system is airtightly connected to the box; the CO2 concentration control and monitoring system comprises a CO2 detector (17) and a high-purity air cylinder (14); the aquatic plant culture and 15N labeling device comprises water containing 15N markers and a hydroponic box for aquatic plants; and the sampling system comprises a gas sampling device and a water sampling device. This isotope dual labeling device can simultaneously and continuously collect gas and water samples, accurately control the CO2 concentration and the 15N marker concentration, and can simultaneously simulate the environmental conditions of elevated atmospheric CO2 concentration and eutrophication of water bodies, and explore the relevant issues of carbon and nitrogen cycles in the complex system of atmosphere-plant-water-microorganism under such environmental conditions.

When the sealing plate 13 enters the interior of the inlet 12, the inlet 12 can be sealed by the rubber ring 48, and at the same time, the sealing block 47 will be driven to enter one end of the sliding groove 45 to seal and protect one end of the sliding groove 45.

[0054] Working principle: First, when using the continuous labeling monitoring device for plant carbon isotopes to label and monitor the carbon isotopes of plants, the plant to be monitored is placed in the storage groove 23, and then the storage groove 23 is placed in the square groove 22, and then the support plate 14 is used to support the plant, and the driving motor 21 is electrically connected to the controller 2. The driving motor 21 is controlled by the controller 2 to drive the threaded rod 20 to rotate, and the threaded rod 20 rotates to move the threaded cylinder 19, and the threaded cylinder 19 moves to drive the support plate 14 to move. When the support plate 14 moves, it drives the guide groove 17 to slide on the guide plate 18, so that the support plate 14 moves smoothly, and the support plate 14 drives the square groove 22 to move. When the square groove 22 moves, the pull rope 39 will The sliding block 42 is driven to move. When the sliding block 42 moves, the bracket 43 will drive the roller 44 to rotate inside the sliding rail 46, thereby assisting the sliding block 42 to move smoothly. When the support plate 14 is almost completely entered into the box body 1, one side of the sliding block 42 will first contact one end of the sliding groove 45, and then the sliding block 42 will be limited. The sliding block 42 will limit one end of the pull rope 39, and the support plate 14 continues to move, the position of the pull rope 39 will slide, pulling the square block 36 to move, and the movement of the square block 36 drives the sealing ring 37. The square block 36 cooperates with the sealing ring 37 to extract the air inside the negative pressure groove 28, thereby forming a negative pressure inside the negative pressure groove 28, and the position of the storage groove 23 will be limited by the rubber plate 27, thereby effectively avoiding The position of the storage slot 23 is not shaken, which improves the stability of plant storage and effectively avoids accidental shaking of plants during monitoring, causing tipping and plant damage. At this time, the support plate 14 continues to slide into the box body 1. Since the bottom of the square block 36 is in limited contact with the movable slot 35, the square block 36 will drive the support block 24 to move downward, and then drive the storage slot 23 to move downward in the square slot 22, further improving the stability of plant storage. When the support plate 14 completely enters the interior of the box body 1, the sealing plate 13 will enter the inlet 12 to seal the inlet 12. There are three groups of gas storage tanks 6 for storing ordinary carbon dioxide and labeled carbon dioxide. Ordinary carbon dioxide is used for basic carbon isotope measurement, and labeled carbon dioxide is used for basic carbon isotope measurement. It is used to track the absorption and assimilation process of plants to carbon sources. By turning the No. 1 valve 7 on the corresponding gas storage tank 6 to control the opening and closing of the gas storage tank 6, different carbon dioxide can be released into the gas collecting tank 8. The gas will enter the box 1 through the gas supply pipe 10, so that the plant can absorb the gas. The carbon dioxide concentration inside the box 1 is monitored and analyzed by the detection component 16. The absorption of different isotopes by plants during the respiration process can be analyzed to evaluate the dynamic changes of carbon and its circulation process in the ecosystem. Through real-time monitoring by the continuous labeling monitoring device for plant carbon isotopes, the response of plants to environmental changes and the function of their carbon cycle can be effectively studied. The detection component 16 is a sensor that can monitor the carbon dioxide absorption status inside the box 1.When the monitoring of the plants is completed, or when the plants are replaced for monitoring, the output end of the driving motor 21 moves in the opposite direction, which will cause the support plate 14 to slide toward the outside of the box body 1. The movement of the support plate 14 drives the sealing plate 13 to slide outward, and the inlet 12 is no longer sealed. At the same time, the pull rope 39 drives the sliding block 42 to reset, and the pull rope 39 no longer generates tension on the square block 36. The reset of the driving spring 38 will push the square block 36 to reset, so that the inside of the negative pressure groove 28 is no longer negative pressure, and the storage groove 23 is no longer limited. At the same time, the damper 34 and the reset spring 32 will reset, which will push the support block 24 to reset, and then the storage groove 23 will be pushed upward by the support block 24. When the support plate 14 drives the plant to move out of the box body 1, the reset of the support block 24 will push the storage groove 23 to a height that is convenient for the staff to take. The staff can directly take out the storage groove 23, or directly replace and take out the plants inside the storage groove 23, which improves work efficiency and reduces labor intensity.
