[0020] Embodiment

[0021] Please refer to the attached Figures 1 to 4, this application provides a rhizosphere soil microorganism collection device based on non-destructive testing, including a vertical column 1, a collection hopper 2 and a scraping head 3. The lower end of the vertical column 1 is buried in the rhizosphere soil. After taking out the vertical column 1, a cylindrical soil pit is formed in the rhizosphere soil. The collection hopper 2 is connected with a first handle 4, and the scraping head 3 is connected with a second handle 5. The scraping head 3 is used to scrape off the rhizosphere soil on the side wall of the soil pit, and the collection hopper 2 is used to collect the scraped rhizosphere soil. The vertical column 1 is pre-buried in the rhizosphere soil to be sampled. When it is necessary to collect soil microorganisms, the vertical column 1 is pulled out of the soil. After pulling out the vertical column 1, a soil pit is formed in the rhizosphere soil. The collection hopper 2 and the scraping head 3 are inserted into the soil pit through the first handle 4 and the second handle 5. The scraping head 3 is used to collect the soil on the side wall of the soil pit and the rhizosphere soil deeper inside away from the side wall. The collection hopper 2 is located below the scraping head 3, and the scraped soil falls into the collection hopper 2. The collection hopper 2 is taken out of the soil pit to obtain a soil sample. Since the vertical column 1 is pre-buried in the rhizosphere soil, the root system of the plant is blocked by the vertical column 1. After taking out the vertical column 1 for collection, it can prevent damage to the plant root system during the collection process and achieve the effect of non-destructive sampling and testing. After the collection, the vertical column 1 can be reinserted into the soil pit for the next microorganism collection. Sampling can be carried out at different depths of the soil pit to obtain microorganism samples at different soil depths. The vertical column 1 is a hollow column body, and the upper end of the vertical column 1 is provided with an opening, and the opening is provided with a sealing cover 12. The sealing cover 12 is threadedly connected with the vertical column 1. The hollow column body can reduce the production cost and the weight of the vertical column 1. When pre-burying and using, the sealing cover 12 can be opened, and then soil is filled into the hollow vertical column 1 and the sealing cover 12 is covered. Filling the soil can improve the strength of the vertical column 1 on the one hand, and on the other hand, it can make the heat conduction performance of the vertical column 1 close to that of the surrounding soil, which is beneficial to maintaining the physical properties of the surrounding soil and does not affect the test results.

The control switch 8 is used to control the switch of the lighting lamp 6.

[0022] Specifically, a plurality of convex rings 13 are provided on the outer periphery of the top of the column 1. After the column 1 is buried in the soil, the convex rings 13 are embedded in the soil, which can prevent rainwater from flowing downward along the outer edge of the column 1, and is beneficial to maintaining the physical properties of the surrounding soil.

[0023] Specifically, the middle and lower part of the column 1 is frustum-shaped, and the diameter of the lower end of the column 1 is smaller than that of the upper end. It is convenient to bury the column 1 in the soil and also convenient to put the column 1 back into the soil pit again after sampling.
