[0002] Plant rhizosphere exudates are a complex and diverse system encompassing a wide range of organic and inorganic substances released into the soil by plant roots during growth. Broadly speaking, rhizosphere exudates refer to all organic matter released into the soil during root growth, but are sometimes narrowly defined as soluble organic matter that enters the soil through exudation. Root exudates also include low-molecular-weight primary metabolites (such as sugars, amino acids, and organic acids), secondary metabolites (such as phenolics, flavonoids, and terpenes), and inorganic molecules (such as carbon dioxide and water).

The upper end of the chromatography column is also connected to a first liquid inlet funnel, and the lower end is also connected to a recovery bucket. A fifth switch is provided on the connecting pipeline between the lower end and the recovery bucket. This utility model has a simple structure and is easy to operate, facilitating the recycling or identification of root exudates.

[0023] See also Figures 1 to 4 In this embodiment, a plant rhizosphere secretion collection device includes a fixed chassis 1 and a flowerpot body 2 arranged on the top of the fixed chassis 1. A filtering and collecting structure for conveniently collecting plant rhizosphere secretions is provided between the flowerpot body 2 and the fixed chassis 1. The filtering and collecting structure includes a connecting bottle 4 that is threadedly connected to the inside of the flowerpot body 2 and extends to the bottom thereof. A collecting bottle 5 is fixedly connected to the side of the connecting bottle 4 close to the fixed chassis 1. A first filter membrane 7 is provided on the inner bottom wall of the flowerpot body 2. A liquid collecting funnel 6 is clamped inside the connecting bottle 4, and the inner wall of the connecting bottle 4 is in contact with the outer surface of the liquid collecting funnel 6.

[0024] Among them, a threaded ring that is compatible with the outer surface of the connecting bottle 4 is provided on the inner wall of the flowerpot body 2, and a through hole connected to the connecting bottle 4 is provided on the inner bottom wall of the flowerpot body 2. The bottom of the connecting bottle 4 is connected to the interior of the collecting bottle 5. The connecting bottle 4 is a hollow, uncovered cylinder. A fixing plate 9 is fixedly connected to the inner wall of the liquid collecting funnel 6, and a small seepage hole 10 is provided inside the fixing plate 9. A second filter membrane 8 is provided on the upper surface of the fixing plate 9. A liquid collection tube 3 connected to the interior of the collecting bottle 5 is fixedly connected to one side of the collecting bottle 5. The end of the liquid collection tube 3 away from the collecting bottle 5 is slidably connected to a sealed glass cover extending into the interior thereof, which is convenient for the staff to extract the secretions inside the collecting bottle 5. By setting the sealed glass cover, dust can be prevented from falling into the liquid collection tube 3.

[0025] It should be noted that the first filter membrane 7 is in contact with the inner bottom wall of the flower pot body 2, and a threaded groove is provided on the opposite side of the connecting bottle 4 and the liquid collecting funnel 6. The filter pore diameters of the first filter membrane 7 and the second filter membrane 8 are both less than 0.2 μm. The collecting bottle 5 and the connecting bottle 4 are an integrally molded structure. The connecting bottle 4 is made of glass and can be sterilized by using high-pressure steam.

[0026] In addition, by setting the first filter membrane 7, on the one hand, the downward growth of plant roots inside the flowerpot body 2 can be inhibited, and on the other hand, the soil can be prevented from falling, while facilitating the collection of secretions. At the same time, by setting the second filter membrane 8, impurities such as microorganisms can be prevented from penetrating and polluting the secretions.

[0027] In this embodiment, the collecting bottle 5 is fixedly connected to an insertion block 11 extending into the interior thereof near the side of the fixed chassis 1, and a return spring 12 is fixedly connected to the interior of the fixed chassis 1. The return spring 12 is fixedly connected to an elastic block 13 extending into the interior thereof at one end near the insertion block 11. There are four return springs 12 and four elastic blocks 13, and the four elastic blocks 13 and the return spring 12 are evenly distributed around the insertion block 11.

[0028] Among them, the outer surface of the insertion block 11 is provided with a card groove adapted to the elastic card block 13, and the upper surface of the fixed chassis 1 is provided with a positioning groove adapted to the insertion block 11. By setting the reset spring 12 and the elastic card block 13, and then setting the insertion block 11, the elastic card block 13 can be clamped and fixed to the insertion block 11, thereby facilitating the fixing of the entire device on the fixed chassis 1.

[0029] The working principle of the above embodiment is:

[0030] First, the staff sterilizes all the components of the device and assembles the treated components in sequence. First, the second filter membrane 8 is placed inside the liquid collecting funnel 6, and the liquid collecting funnel 6 is fixed inside the connecting bottle 4. Then the connecting bottle 4 and the collecting bottle 5 are fixed to the bottom of the flower pot body 2. At this time, the device is fixed on the fixed chassis 1 through the insertion block 11, and the plants are planted inside the flower pot body 2. After the plants grow to the required period, methanol is dripped downward along the stems of the plants close to the soil. After methanol extracts the plant root secretions, it is dripped into the second filter membrane 8 in the liquid collecting funnel 6 through the first filter membrane 7. The solution obtained after two filtrations flows into the collecting bottle 5 through the liquid collecting funnel 6 to collect the secretions for subsequent testing.
