Specifically, in order to facilitate the distinction, the three groups of the partition net cylinders are defined as a first net cylinder 21, a second net cylinder 22 and a third net cylinder 23 from inside to outside, and the three partition net cylinders are coaxially arranged, wherein the inside of the first net cylinder 21 forms a non-rhizosphere soil zone, the interlayer between the first net cylinder 21 and the second net cylinder 22 forms a partition zone, and the interlayer between the second net cylinder 22 and the third net cylinder 23 forms a rhizosphere soil zone. The non-rhizosphere soil zone and the rhizosphere soil zone are separated by the partition zone, which can improve the accuracy of subsequent detection of the non-rhizosphere soil and the rhizosphere soil zone.

[0038] Further, the potting cylinder 1, the first net cylinder 21, the second net cylinder 22 and the third net cylinder 23 can be assembled in a direct placement manner. Specifically, the bottoms of the potting cylinder 1, the third net cylinder 23 and the second net cylinder 22 are provided with positioning grooves matched with the third net cylinder 23, the second net cylinder 22 and the first net cylinder 21 respectively, so as to facilitate the placement of the partition net cylinders.

[0039] The working principle of the utility model is as follows:

[0040] ​During implementation, soil is filled into the gaps between the various partitioned mesh cylinders, and vegetables are planted in the planting area formed between the third mesh cylinder 23 and the second mesh cylinder 22. When the vegetables mature, the insertion part 411 of the connector is rotated out partially so that the top block 414 of the clamping member corresponds to the end part 3 at the top of the first mesh cylinder 21. At this time, the position of the top block 414 is adjusted by rotating the push rod 413 so that the top block 414 is clamped on the outside of the end part 3, wherein the protrusion 4141 of the top block 414 is inserted into the insertion groove 31. Then, the push rod is used to adjust the position of the top block 414. The rod 413 drives the insertion part 411 to rotate and unscrew in the annular groove, causing the insertion part 411 to move upward in the annular groove, which in turn moves the first mesh cylinder 21 upward until it is removed from the potting cylinder 1, thus obtaining the soil in the non-rhizosphere soil area. Then, the insertion part 411 is screwed into the annular groove, so that the top block 414 corresponds to the end part 3 of the second mesh cylinder 22 and the third mesh cylinder 23 in sequence. Using the above steps, the soil in the separation area and the rhizosphere soil area are taken out in sequence for separate testing. Finally, the potting cylinder 1 is lifted and taken out by holding the handle 5.

[0041] In summary, the potted plant rhizosphere soil zoning sampling device of this utility model has the following technical advantages: 1. The zoning component of this utility model separates the non-rhizosphere soil area from the rhizosphere soil by setting several sequentially nested dividing mesh tubes inside the potting tube, so that non-rhizosphere soil or rhizosphere soil can be collected in the corresponding dividing mesh tubes; 2. The sampling component of this utility model has a connecting member that can move up and down along the potting tube, and a clamping member that can fix the dividing mesh tube, thereby driving the dividing mesh tube to move upward until it is removed from the potting tube, so as to realize the zoning sampling of the potted plant rhizosphere soil; 3. The several dividing mesh tubes of this utility model increase in height from the outside to the inside, so that the top of each layer of dividing mesh tube has sufficient connection position, so that the user can use the sampling component to remove each dividing mesh tube separately, thereby obtaining the soil of each area separately, without causing non-rhizosphere soil and rhizosphere soil to mix during removal, thus improving the accuracy of soil testing in each area.

[0042] Therefore, compared with the existing potted plant rhizosphere soil zoning sampling technology, the potted plant rhizosphere soil zoning sampling device provided by this utility model has obvious technical advantages.
