Description

Technical Field

[0001] This utility model relates to the field of indoor wheat identification, and in particular to an indoor identification platform for wheat cold resistance that is temperature and light adjustable and eliminates position effects. Background Technology

[0002] Indoor identification of wheat cold resistance is a technical method that systematically evaluates the cold resistance of wheat varieties by simulating low-temperature stress under controlled environmental conditions. This method typically utilizes artificial climate chambers or customized culture devices to precisely control parameters such as temperature, light, humidity, and wind speed. It then conducts multi-dimensional evaluations using physiological, biochemical, and morphological indicators, ultimately achieving standardized, high-throughput identification of cold resistance phenotypes. This overcomes the limitations of traditional field identification, which is affected by environmental fluctuations, and provides reliable data support for the breeding of cold-resistant varieties and the study of their mechanisms.

[0003] Traditional methods for assessing wheat cold resistance often involve planting in natural low-temperature environments or using simple incubators. These methods are frequently affected by inaccurate temperature control, uncontrollable wind speed, and unstable environmental parameters. Furthermore, existing equipment struggles to eliminate position effects and cannot provide intelligent environmental control and dynamic monitoring, resulting in extremely poor repeatability and failing to meet the need for accurate assessment of wheat cold resistance.

[0004] Therefore, in view of the problems that traditional wheat cold resistance identification methods often use natural low-temperature environment planting or simple incubators, which are often affected by inaccurate temperature control, uncontrollable wind speed and unstable environmental parameters, and the existing equipment is difficult to eliminate position effect, resulting in extremely poor repeatability and difficulty in meeting the needs of accurate wheat cold resistance identification, a temperature and light adjustable indoor wheat cold resistance identification platform that also eliminates position effect can be designed.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment: a temperature and light adjustable indoor wheat cold resistance identification platform that also eliminates position effects includes a fixed frame 1; it also includes a turntable 15. Rubber and plastic insulation boards 2 are respectively arranged on the left and right sides of the fixed frame 1, and the same rubber and plastic insulation board 2 is arranged at the rear end of the fixed frame 1. A windproof polyester cloth 3 is arranged at the front end of the fixed frame 1, and a breathable gauze 4 is arranged on the top of the fixed frame 1. A support frame 5 is arranged on the top of the fixed frame 1, and a nylon mesh 6 is arranged on the outer surface of the support frame 5. Multiple round holes 7 are opened on the top of the nylon mesh 6. A motor 14 is fixedly connected to the bottom of the fixed frame 1, and the output end of the motor 14 is fixedly connected to the turntable 15. The turntable 15 is rotatably connected to the fixed frame 1. The motor 14 drives the turntable 15 to rotate. This temperature and light adjustable wheat cold resistance identification platform reduces airflow disturbance through the windproof polyester cloth 3 on the front and forms a buffer layer with the double-layer roof design to reduce vertical wind speed fluctuations. At the same time, the perforated design in the central area of ​​the nylon mesh 6 promotes air convection and balances the temperature gradient between the upper and lower parts, ensuring the stability of the low temperature environment. Meanwhile, the turntable 15 drives the plants to rotate periodically, eliminating the microenvironmental differences between the edge and the center. This makes the temperature control of natural low-temperature planting or simple incubators more precise, the wind speed control more controllable, and reduces large environmental fluctuations and position effects. It significantly improves the environmental uniformity and data repeatability of cold resistance identification, providing a reliable technical platform for the accurate evaluation of wheat cold resistance.

[0024] Please see Figures 2-4In this embodiment, two connecting frames 8 are fixedly connected to the inner side of the fixing frame 1. A cold light source LED tube 9 is fixedly connected to the inner side of the connecting frame 8. The dual-sided light reduces the shadow effect of unidirectional light and makes the plant receive light evenly. It works with the turntable 15 to further balance light absorption. Two temperature sensing probes 11 are set at the bottom of the wooden board 16. The dual probes at the center and 30cm from the edge can monitor the radial temperature difference and provide real-time feedback on environmental parameters. If an abnormal temperature is detected, automatic intervention is performed. Four fixing rods 12 are fixedly connected to the four corners inside the fixing frame 1. A high-sensitivity anemometer 13 is fixedly connected to the top of the fixing rods 12 to ensure that it does not interfere with the plant or the turntable 15. It quantifies the uniformity of wind speed in the device, ensures low wind speed and no turbulence, and avoids wind stress interfering with the cold resistance assessment.

[0025] Please see Figures 1-3 In this embodiment, a wooden board 16 is fixedly connected to the top of the turntable 15, and a slide rail 17 is provided between the wooden board 16 and the fixed frame 1. The plant is placed on the wooden board 16 and rotates with the turntable 15, so that the plant periodically exchanges positions, eliminating the environmental difference between the edge and the center, and making the data more reliable.

[0026] During operation, the windproof polyester fabric 3 on the front reduces airflow disturbance, while the breathable gauze 4 and nylon mesh 6 of the double-layered roof form a buffer layer with a 20cm spacing, reducing vertical wind speed fluctuations. Simultaneously, the perforated central area of ​​the nylon mesh 6 allows for air convection to balance the temperature gradient within the device. The rubber and plastic insulation boards 2 on the sides and back effectively reduce external temperature interference, meeting the low-temperature requirements of cold resistance tests. The turntable 15 rotates the wooden board 16 and the plants, allowing the plants to periodically exchange positions, eliminating environmental differences between the edges and the center. During use, the plant container is placed on the wooden board 16, and two cold-light LED tubes 9 reduce unidirectional light. The shading effect ensures uniform light exposure for the plants, and the turntable 15 further balances light absorption. Two temperature sensors 11 monitor radial temperature differences and provide real-time feedback on environmental parameters. If an abnormal temperature is detected, automatic intervention is initiated. A high-sensitivity anemometer 13 is positioned at the four corners and installed at a height of 1.2m to ensure no interference with the plants or the turntable 15. This quantifies the uniformity of wind speed within the device, ensuring low wind speeds and no turbulence, thus avoiding wind stress interference with cold resistance assessment. The plants are placed on a wooden board 16 and rotate with the turntable 15, causing the plants to periodically change positions, eliminating environmental differences between the edges and the center, and making the data more reliable. The temperature is controlled by the controller 10.

[0027] Through the above steps, the windproof polyester fabric 3 on the front reduces airflow disturbance, and the breathable gauze 4 and nylon mesh 6 of the double-layered roof form a buffer layer with a 20cm spacing, reducing vertical wind speed fluctuations. At the same time, the perforated area of ​​the nylon mesh 6 allows the air convection to balance the temperature gradient inside the device. The rubber and plastic insulation boards 2 on the sides and back effectively reduce external temperature interference, which is suitable for the low-temperature requirements of cold resistance tests. The turntable 15 drives the wooden board 16 and the plant to rotate, which allows the plant to periodically exchange positions and eliminate the environmental differences between the edge and the center. This solves the problem that traditional wheat cold resistance assessment often uses natural low-temperature environment planting or simple incubators, which are often affected by inaccurate temperature control, uncontrollable wind speed and unstable environmental parameters. Furthermore, existing equipment is difficult to eliminate position effects, resulting in extremely poor repeatability and making it difficult to meet the requirements for accurate assessment of wheat cold resistance.
