Description

Technical Field

[0001] This utility model relates to the technical field of plant community photosynthesis detection equipment, and in particular to a plant community photosynthesis detection box system. Background Technology

[0002] Existing plant photosynthesis monitoring chambers do not have the function of supplying carbon dioxide and cannot regulate the carbon dioxide concentration inside the chamber. This makes it impossible to study the photosynthetic capacity of plants under different carbon dioxide concentrations under the existing plant photosynthesis monitoring chamber conditions. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a carbon dioxide supply system for a photosynthesis detection box array, so as to solve the technical problem of creating carbon dioxide concentration conditions as required for plants in different photosynthesis detection boxes in the study of plant photosynthetic capacity.

[0004] The carbon dioxide supply system for the photosynthesis detection box array of this utility model includes a carbon dioxide supplier, a main supply pipe connected to the carbon dioxide supplier, and a supply branch pipe connected to the main supply pipe. The supply branch pipe is connected to the photosynthesis detection box and is equipped with an electric valve.

[0005] The carbon dioxide supply system of the photosynthesis detection box array also includes a carbon dioxide concentration sensor for detecting the carbon dioxide concentration in the photosynthesis detection box, and the carbon dioxide concentration sensor is connected to the controller of the electric valve.

[0006] Furthermore, the carbon dioxide supply system of the photosynthesis detection box array also includes a pressure balancing structure installed on the photosynthesis detection box to balance the internal and external air pressure.

[0007] Furthermore, the pressure balancing structure is a relaxed thin film disposed on the window and the sealing window of the photosynthesis detection box.

[0008] The beneficial effects of this utility model are:

[0009] The carbon dioxide supply system of the photosynthesis detection box array in this invention can independently regulate the carbon dioxide concentration in each photosynthesis detection box, so that the carbon dioxide concentration rises to the required concentration value, thereby providing different carbon dioxide concentration conditions for studying the photosynthetic capacity of plants. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the carbon dioxide supply system for the photosynthesis detection box array. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] In this embodiment, the carbon dioxide supply system for the photosynthesis detection box array includes a carbon dioxide supplier 1, a main supply pipe 2 connected to the carbon dioxide supplier, and a branch supply pipe 3 connected to the main supply pipe. The branch supply pipe is connected to the photosynthesis detection box, and an electric valve 4 is installed on the branch supply pipe. In specific implementations, the carbon dioxide supplier 1 can be an existing device such as a carbon dioxide compressed gas cylinder or a carbon dioxide generator.

[0013] The carbon dioxide supply system for the photosynthesis detection box array also includes a carbon dioxide concentration sensor 5 for detecting the carbon dioxide concentration inside the photosynthesis detection box. The carbon dioxide concentration sensor is connected to a controller 6 for the electric valves. In specific implementations, each electric valve can have its own controller, or multiple electric valves can share a single controller.

[0014] In practical work, different carbon dioxide concentrations can be set for each photosynthesis detection box as needed. The carbon dioxide supplier 1 outputs carbon dioxide gas, and the controller 6 controls the electric valve 4 to open so that the carbon dioxide gas enters the photosynthesis detection box through the supply branch pipe 3. When the carbon dioxide concentration sensor 5 detects that the carbon dioxide concentration has risen to the set value, the controller 6 controls the corresponding electric valve 4, thereby adjusting the carbon dioxide concentration in the corresponding photosynthesis detection box to the set value.

[0015] As an improvement to the above embodiment, the carbon dioxide supply system of the photosynthesis detection box array further includes a pressure balancing structure disposed on the photosynthesis detection box to balance the internal and external air pressure. In this embodiment, the pressure balancing structure consists of a window and a relaxed film 7 for sealing the window disposed on the photosynthesis detection box. The air pressure inside the photosynthesis detection box may affect the plant's ability to perform photosynthesis. If the air pressure is too high, the stomata on the plant leaves may partially close, thereby reducing the plant's photosynthesis. This improvement addresses this by providing a relaxed film 7 on the photosynthesis detection box. When carbon dioxide gas is supplied into the photosynthesis detection box, the increased air pressure inside the box drives the relaxed film 7 to expand outward, thereby increasing the internal space. This allows the air pressure inside the box to decrease and return to a state equal to the external air pressure, thus avoiding the problem of increased air pressure inside the box caused by supplying carbon dioxide.

[0016] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and such modifications or substitutions should all be covered within the scope of the claims of this utility model.
