The traditional rhizosphere soil collection method has many limitations when applied to medicinal plants. When the traditional digging method is used to obtain rhizosphere soil, the plant root system is greatly damaged, the growth of medicinal plants is disturbed, the sample purity is low, and the subsequent research is not conducive. Although the micro-root window technology combined with the soil collection method can be observed and collected in situ, the equipment is expensive, the operation is complex, and the soil purity is affected by many factors. The PVC frosted plate method has certain convenience in potting, but it cannot collect multiple parts of the plant root during the growth of the plant. SUMMARY

[0004] To achieve the above purpose, the technical idea adopted by the utility model to solve its technical problems is:
[0005] The device is composed of an internal culture cylinder and an external rotatable sampling cylinder. Rotating the sampling cylinder can accurately control the coincidence degree of the two cylinder walls, and the soil collection amount can be flexibly adjusted. Water can be sprayed through the sampling port to guide the roots to grow towards the cylinder wall during plant growth. Along the growth direction of the plant roots, three sampling ports are vertically arranged to collect soil at different positions, which helps to accurately obtain rhizosphere soil at specific positions during different growth periods and deeply explore the interaction between roots and soil.
[0006] The cylindrical and adjustable sampling port design has multiple advantages. When not collecting, the sampling ports are staggered to form a stable space in the culture cylinder, reducing external interference; when collecting, it causes less root damage than digging, which is beneficial to the growth of rare or long-term medicinal plants, and occasional rotation of the sampling port can increase soil permeability.
[0007] The sampling port is in the shape of a small inner and large outer horn, which is suitable for different types of soil, small inside to prevent soil particles from falling, and large outside to facilitate operation. The transparent culture cylinder and sampling cylinder facilitate observation of root growth and soil collection process, so that timely adjustment can be made to improve the accuracy and effectiveness of soil collection and provide strong support for the research of rhizosphere soil of medicinal plants.

[0025] The technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments, and not all the embodiments.
[0026] In the description of the utility model, it needs to be understood that the terms "front", "back", "left", "right", "up", "down", "top", "bottom", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.
[0027] Reference Figs. 1-3 The utility model provides a kind of rhizome medicinal plant root soil collection tool, including culture cylinder 10 and the sampling cylinder 20 of being set to culture cylinder 10 outside.
[0028] Specific implementation, culture cylinder 10 is cylindrical, its height range is set between 35 and 55 centimeters, and the thickness of cylinder wall is maintained at 2 to 3 centimeters.The culture cylinder is made of transparent acrylic material, which has certain transparency, so that the user can clearly observe the growth condition of plant root system.Sampling cylinder 20 is also cylindrical, its height is slightly lower than culture cylinder, in the interval of 30 to 50 centimeters, to facilitate operator to adjust the soil or plant in culture cylinder 10, and the inner diameter is slightly larger than the outer diameter of culture cylinder 10, so that culture cylinder 10 can rotate flexibly in sampling cylinder 20, and the two are closely fitted, effectively prevent soil residue from falling into the gap between them.Sampling cylinder 20 also uses transparent acrylic material, which is convenient for observation during sampling.A bearing 30 is arranged at the bottom of the inside of sampling cylinder 20, and the bottom of culture cylinder 10 is fixed on the upper end of bearing 30, so that culture cylinder 10 can rotate smoothly and stably in sampling cylinder 20.
[0029] Specific implementation, three sampling ports one 11 are arranged on the cylinder wall of culture cylinder 10 in vertical direction, to facilitate sampling of rhizosphere soil of plants in different growth stages, and the specific number of sampling ports can be adjusted according to specific needs.Each sampling port one 11 is a strip-shaped opening with a horn-shaped shape, which gradually increases from inside to outside, and the length is designed to be between 10-15 centimeters, and the inside width of the opening is 2-3 centimeters.The edge has a curvature to avoid scratching or damaging the root system during the growth of the plant root system.Two protrusions 12 are further arranged on the upper end surface of culture cylinder 10, and the distance between the two protrusions 12 is equal to the length of sampling port one 11, so that when culture cylinder 10 rotates in sampling cylinder 20, the position of protrusion 12 can be observed to accurately determine the position of sampling port one 11 for convenient sampling.
[0030] Three sampling openings two 21 are formed on the corresponding positions of the cylinder wall of the sampling cylinder 20. The sampling openings two 21 are also strip-shaped openings and are in the shape of a trumpet mouth, and the openings gradually increase from inside to outside. The length of the sampling openings two 21 is between 5-8 cm, and the width is equal to the height of the outside of the sampling opening one 11. When the two openings coincide, a smooth soil collection channel is formed, which facilitates the multi-angle collection of soil by the operator using a tool. When a scraper is used for collection, the soil can also slide along the slope to avoid being stuck in the gap.
[0031] Working principle: first, the rhizome medicinal plant is planted in the culture cylinder 10. During the growth of the plant, the growth of the root system can be observed in real time through the transparent culture cylinder 10 and the sampling cylinder 20. The culture cylinder 10 is rotated to spray appropriate moisture through the sampling opening, and the plant rhizome is guided to grow in the direction of the sampling opening. After spraying, the two sampling openings are staggered, and the device is covered with a shading cloth to facilitate plant growth.
[0032] When the soil at the root is needed to be collected, the culture cylinder 10 is rotated so that the sampling opening one 11 on the culture cylinder 10 coincides with the sampling opening two 21 on the sampling cylinder 20, forming a soil collection channel. The culture cylinder 10 can also be rotated so that the sampling opening two 21 slides on the sampling opening one 11, which facilitates the sampling of rhizosphere soil in different areas. At this time, the operator can collect soil samples through the channel by using a scraper and other tools.
[0033] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
