Description

Technical Field

[0001] This utility model relates to the field of seedling trait measurement technology, and in particular to a multi-parameter trait measurement device for seedlings in molecular breeding. Background Technology

[0002] In the cutting-edge field of molecular breeding, the precise measurement of multi-dimensional parameters of seedlings has always been a crucial link in promoting the advancement of breeding technology. Among these, the determination of parameters related to plant photosynthesis is of paramount importance. Photosynthesis in plants is not only the energy source for their growth and development but also a core physiological process that determines crop yield and quality. In the process of molecular breeding, measuring devices such as plant photosynthesis meters are used to measure plant photosynthetic parameters.

[0003] However, while traditional plant photosynthesis measuring instruments can measure parameters such as leaf surface temperature, leaf photosynthetic rate, and leaf transpiration rate, they still have some problems in practical applications. For example, in strong sunlight outdoors, the instrument's display screen is easily interfered with by strong light, making the data on the screen difficult to read. This affects the data reading efficiency and makes it difficult to ensure the smooth progress of the measurement work. In terms of portability, the main body and the measuring handle need to be carried separately. If the measuring handle is placed directly on top of the main body, it will create the risk of the measuring handle falling, which not only increases the risk of loss but also brings many inconveniences to the user. Therefore, it is difficult to meet the portability needs of breeders when they travel to multiple locations. Utility Model Content

Through the cooperation of a light-shielding component and a limiting component, the device effectively shields the display screen from strong sunlight during measurement. This allows for viewing the data on the screen even in strong sunlight, preventing disruption to data reading efficiency and ensuring the smooth progress of the measurement work. Furthermore, the clamping groove and clamping component allow for secure clamping of the measuring handle when carried outdoors, reducing the likelihood of the handle falling or being lost and providing significant convenience to the user.

[0010] This invention provides a device for measuring multiple parameters of seedling traits in molecular breeding, which has the following beneficial effects:

[0011] 1. Through the cooperation of the light-shielding component and the limiting component, when encountering strong sunlight during the measurement process, simply pull the handle backward and then move the moving frame plate upward to unfold the foldable light-shielding cloth. The unfolded foldable light-shielding cloth can then effectively shield the display screen from the light, allowing the data displayed on the screen to be viewed even in strong sunlight, avoiding affecting the data reading efficiency and thus ensuring the smooth progress of the measurement work.

[0012] 2. With the design of the clamping groove and clamping components, when carrying the device out, simply pull the movable clamping block upwards, place the measuring handle between the movable and fixed clamping blocks, and then release the movable clamping block.

Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1: Please refer to Figures 1 to 5 :

[0029] This invention proposes a multi-parameter trait measurement device for seedlings in molecular breeding, comprising: a plant photosynthesis meter body 1, with a display screen 101 on the top of the plant photosynthesis meter body 1; a light-shielding component 2 located on the outside of the display screen 101 on the top of the plant photosynthesis meter body 1; a clamping groove 102 is formed on the right side of the front end face of the plant photosynthesis meter body 1, and a clamping component 3 is provided inside the clamping groove 102, with a measuring handle 5 clamped on the clamping component 3, which can be connected to the plant photosynthesis meter body 1 via a cable; the light-shielding component 2 includes a foldable light-shielding cloth 201, a movable frame plate 202, an L-shaped sliding rod 203, a limiting insertion hole 204, and a rectangular sliding sleeve 205, with the lower end of the foldable light-shielding cloth 201 fixedly connected to the plant photosynthesis meter body 1. The top of the main body 1 of the plant photosynthesis measuring instrument is covered by a foldable light-blocking cloth 201 located outside the display screen 101. A movable frame plate 202 is fixedly connected to the upper end of the foldable light-blocking cloth 201, and an L-shaped sliding rod 203 is fixedly connected to the rear side of the movable frame plate 202. A rectangular sliding sleeve 205 is slidably connected to the outside of the L-shaped sliding rod 203 and fixed to the upper part of the rear end face of the main body 1 of the plant photosynthesis measuring instrument. A limiting component 4 is installed on the rear end face of the rectangular sliding sleeve 205. Limiting holes 204 are uniformly opened on the rear end face of the L-shaped sliding rod 203. An L-shaped cable support 103 is uniformly fixedly connected to the lower part of the right end face of the main body 1 of the plant photosynthesis measuring instrument. The L-shaped cable support 103 is used to support the cable connecting the main body 1 of the plant photosynthesis measuring instrument and the measuring handle 5.

[0030] The limiting component 4 includes a rectangular sliding shell 401, a rectangular sliding block 402, a pull handle 403, and a limiting rod 404. The rectangular sliding shell 401 is fixedly installed on the rear end face of the rectangular sliding sleeve 205, and the rectangular sliding block 402 is slidably connected inside the rectangular sliding shell 401. The pull handle 403 is fixedly connected to the upper end of the rectangular sliding block 402, and the limiting rod 404 is fixedly connected to the front end of the rectangular sliding block 402. The limiting rod 404 passes through the front side wall of the rectangular sliding shell 401 and the rear side wall of the rectangular sliding sleeve 205. When the limiting component 4 is in the limiting state, the limiting rod 404 is inserted into one of the limiting holes 204. At this time, the L-shaped sliding rod 203 and the movable frame plate 202 can be effectively limited.

[0031] Example 2, based on Example 1, such as Figure 1 and Figure 4As shown, the clamping component 3 includes a fixed clamping block 301, a movable clamping block 302, a rectangular slide cylinder 303, and a rectangular slide column 304. The fixed clamping block 301 is fixedly installed on the bottom surface inside the clamping groove 102. Three rectangular slide cylinders 303 are uniformly fixedly connected to the top surface of the movable clamping block 302, and a rectangular slide column 304 is slidably connected inside each rectangular slide cylinder 303. The upper ends of the three rectangular slide columns 304 are fixedly connected to the top surface inside the clamping groove 102. A spring is provided inside each rectangular slide cylinder 303 at the lower end of the rectangular slide column 304. The measuring handle 5 is clamped between the fixed clamping block 301 and the movable clamping block 302. With the setting of the clamping component 3, when going out, only the main body 1 of the plant photosynthesis measuring instrument needs to be carried, which not only reduces the probability of the measuring handle 5 falling off and being lost during the carrying process, but also brings great convenience to the user.

[0032] The working principle of this embodiment is as follows: When using this device, if the breeder is traveling to multiple locations, first pull the movable clamp 302 upward, then place the measuring handle 5 between the movable clamp 302 and the fixed clamp 301, and then release the movable clamp 302. At this time, the movable clamp 302 moves downward under the action of the spring force inside the rectangular slide cylinder 303, thereby clamping and fixing the measuring handle 5. Then, only the main body 1 of the plant photosynthesis measuring instrument needs to be carried, thus meeting the carrying needs of the breeder when traveling to multiple locations.

[0033] Upon arrival at the measurement location, pull the movable clamp 302 upwards, then remove the measuring handle 5 from between the movable clamp 302 and the fixed clamp 301 for use. Then, use the measuring handle 5 to measure the leaf surface temperature, leaf photosynthetic rate, leaf transpiration rate and other trait parameters of the seedlings during the breeding process.

[0034] During the measurement process, when encountering strong sunlight, first, manually pull the handle 403 backward, moving the rectangular sliding block 402 and the limiting rod 404 backward, so that the limiting rod 404 is pulled out from the limiting hole 204. Then, move the moving frame plate 202 upward, so that the foldable light-blocking cloth 201 is in the unfolded state. Then, release the handle 403, so that the limiting rod 404 is inserted into the limiting hole 204. Then, through the unfolded foldable light-blocking cloth 201, the display screen 101 can be effectively shielded from the light. At this time, the data displayed on the display screen 101 can be viewed in the strong sunlight.
