Technical Field

[0001] This utility model relates to the field of sampling and collection technology, and in particular to a device for collecting corn root exudates. Background Technology

[0002] As a globally important food, feed, and industrial raw material crop, maize's root exudates (such as organic acids, sugars, and amino acids) play a crucial role in nutrient absorption, soil microbial interactions, and stress response. Accurately collecting and analyzing maize root exudates is a core prerequisite for revealing the mechanisms of maize-environment interaction, cultivating high-light-efficiency and stress-resistant varieties, and optimizing fertilizer management.

[0003] However, existing corn root exudate collection devices mainly rely on soil culture, hydroponics, or sand culture systems. Soil culture devices extract exudates directly from the soil, which easily leads to the mixing of soil particles and microbial metabolites, resulting in insufficient purity of the exudates. Therefore, a corn root exudate collection device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that soil cultivation devices directly extract secretions from the soil, which easily mix in soil particles and microbial metabolites, resulting in inconsistent secretion purity.

A filter layer 4 is provided inside the cultivation trough 2 above the fixed mesh plate 3, which can stabilize the filter layer 4 and thus filter secretions. A sterile substrate layer 5 is provided inside the cultivation trough 2 above the filter layer 4, which can be used to plant corn seedlings. An inclined plate 6 is fixedly connected inside the cultivation trough 2 below the fixed mesh plate 3. A trapezoidal plate 7 is fixedly connected to one side wall of the cultivation trough 2 below the inclined plate 6. The bottom inner wall of the cultivation trough 2... Furthermore, a funnel groove 9 is provided near the center, which allows secretions to fall onto the surface of the inclined plate 6. The secretions can then slide onto the trapezoidal plate 7 and fall into the funnel groove 9. An arc hole 10 is provided at the bottom of the funnel groove 9, and a collection groove 12 is provided on one side wall of the incubator 1 near the bottom. The arc hole 10 is connected to the collection groove 12, which allows the secretions in the funnel groove 9 to drip from the arc hole 10 into the collection groove 12. A U-shaped cavity 19 is provided inside the incubator 1 and on one side of the collection groove 12. Cooling pipes 20 are installed at equal intervals inside the U-shaped cavity 19, which can cool the inside of the collection groove 12.

[0021] Example 2: Figures 1-3 As shown, baffles 8 are fixedly connected to both sides of the trapezoidal plate 7; a solenoid valve 11 is installed inside the incubator 1 and on one side of the arc hole 10; a base plate 14 is provided at the bottom of the collection tank 12, and a placement groove 15 is opened at the top of the base plate 14; a sealing plate 16 is embedded and installed on one side wall of the incubator 1 and located in the collection tank 12, and the base plate 14 and the sealing plate 16 are fixedly connected; a drain head 13 is fixedly installed on the top inner wall of the collection tank 12 and located in the arc hole 10; a handle 17 is fixedly connected to the surface of the sealing plate 16; a control panel 18 is fixedly installed on one side wall of the incubator 1 and above the sealing plate 16; a temperature sensor 21 is fixedly installed on the bottom inner wall of the U-shaped cavity 19.

[0022] In this embodiment, baffles 8 are fixedly connected to both sides of the trapezoidal plate 7, which can limit the secretions; a magnetic valve 11 is installed inside the incubator 1 on one side of the arc hole 10, which can control the opening and closing of the arc hole 10; a base plate 14 is provided at the bottom of the collection tank 12, and a placement slot 15 is opened at the top of the base plate 14, which can facilitate the placement of the collection bottle; a sealing plate 16 is embedded and installed on one side wall of the incubator 1 at the collection tank 12, and the base plate 14 and the sealing plate 16 are fixedly connected.

[0023] The working principle of this embodiment is as follows: In use, corn seedlings are first planted in the sterile substrate layer 5 of the culture tank 2, allowing the roots to grow naturally within the sterile substrate layer 5. The substances secreted by the corn roots pass through the filter layer 4 and the fixed mesh plate 3 in sequence, slide along the inclined plate 6 under the action of gravity, and flow into the funnel trough 9 after being limited by the baffle 8 of the trapezoidal plate 7. The solenoid valve 11 is opened through the control panel 18, and the secretions flow into the collection bottle in the placement tank 15 through the arc hole 10 and the drain head 13. The refrigeration pipe 20 in the U-shaped cavity 19 operates under the monitoring of the temperature sensor 21, maintaining the temperature in the collection tank 12 within a suitable range to prevent the secretions from deteriorating. When it is necessary to replace the collection bottle, the handle 17 is pulled to move the sealing plate 16 and the bottom plate 14 out, and the collection bottle in the placement tank 15 can be replaced. After the replacement is completed, the bottom plate 14 is pushed back into the collection tank 12, and the solenoid valve 11 and the refrigeration pipe 20 are controlled through the control panel 18 to achieve continuous and pure collection of root secretions.
