The main method at present is through root sampling inspection. For herbaceous plants, conducting root system research is an important means to understand the growth of plants. Relatively speaking, root sampling is more difficult. In the past, people often used excavation methods, whole specimen methods, profile methods, glass wall methods, mesh bag methods, etc. to take samples, but these methods are relatively cumbersome, time-consuming and labor-intensive, so sampling devices appeared to sample the soil.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example 1

[0048] Please also read Figures 1 to 10 Now, a specific embodiment of a soil-taking device provided by the present invention is described. The soil-taking device comprises: a soil-taking barrel 1, a protective component 2, and a handle 3. One end of the soil-taking barrel 1 is provided with a soil-cutting blade 13, and the other end is a connecting end 12. An anti-slip structure 14 is provided on the inner wall of the soil-taking barrel 1. The diameter of the end of the soil-cutting blade 13 on the soil-taking barrel 1 is smaller than the diameter of the connecting end 12. The protective component 2 is connected to the soil-taking barrel 1 and is provided at the connecting end 12; the handle 3 is connected to the protective component 2.

[0049] One end of the soil sampling tube 1 is a cutting end 11, and the other end is a connecting end 12. The soil sampling tube 1 is a truncated cone structure. The diameter of the cutting end 11 is smaller than the diameter of the connecting end 12. During the sampling process, the area of ​​the soil sampling tube 1 that the soil sample contacts becomes larger, making the soil sample gradually fluffy. The volume of the fluffy soil sample increases, preventing the soil sample from slipping. The anti-slip structure 14 is used to prevent the soil sample from slipping from the soil sampling tube 1. The cutting end 11 of the soil sampling tube 1 is provided with a soil cutting blade 13 with a sharp lower edge, which facilitates the soil sampling tube 1 to penetrate deeply into the soil. Sampling process: Put the soil sampling tube 1 on the herbaceous plant to be taken, and ensure that the plant is in the center of the soil sampling tube 1, press it vertically downward through the handle 3, and when the required depth is reached, drive the soil sampling tube 1 to rotate through the handle 3 to separate the soil body, and then gently lift it up to complete the soil sampling. For example, the soil sampling tube 1 has a tube height of 20 cm, an outer diameter of 11.2 cm, an inner diameter of 10.8 cm, a diameter of the cutting end 11 of 10.4 cm, and a tube thickness of 0.2 cm. It should be understood that the terms "upper", "lower", "inner", "vertical", etc., indicating positions or positional relationships based on the positions or positional relationships shown in the drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0050] Compared with the prior art, this soil sampling device is suitable for experimental research on plant growth conditions. The diameter of the cutting end 11 of the soil sampling tube 1 is smaller than the diameter of the connecting end 12. When the soil sample entered the soil sampling tube 1, it is gradually tightened into the soil sampling tube 1 due to the cutting of the soil cutting blade 13. As the soil sampling tube 1 moves downward, the soil sampling tube 1 gradually widens, preventing the soil sample from slipping. The anti-slip structure 14 on the inner wall of the soil sampling tube 1 increases the friction force on the soil sample. This soil sampling device has a high soil sampling success rate and high efficiency, and solves the problem of the existing root sampler that the soil sample often slips, affecting the soil sampling effect, or repeated soil sampling causes the plant roots and stems to be damaged during the soil sampling process. At the same time, the present invention has a simple structure and significant effect, and is suitable for wide promotion.
