[0002] Corn is an important food and feed crop in my country, and also the world's highest-yielding crop. Currently, its planting area in my country is around 300 million mu (approximately 20 million hectares), ranking third among food crops after rice and wheat. A large amount of organic matter is introduced into the soil through the roots and litter, which is a major pathway influencing the underground material cycle and energy flow. Plant root exudates and absorbents play a crucial regulatory role in soil nutrient cycling by affecting various chemical elements in the roots. This is essential for maintaining crop growth and ecosystem stability. Corn faces various adversities during its growth, such as drought, floods, and pests and diseases. Root sampling can analyze the root response mechanisms of corn under adversity conditions, providing clues for cultivating resilient varieties. Therefore, a single-plant root in-situ sampling device for corn is proposed to facilitate sampling of corn plant roots for research and testing. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Refer to Figure 1-4 A corn single-plant root in-situ sampling device includes a sampling placement sleeve 1, with a central plant perforation 2 in the middle of the sleeve 1. Multiple side-fixed sliding rods 3 are fixedly installed on the side of the sleeve 1, and sliding sleeves 4 are slidably sleeved on the side-fixed sliding rods 3. An arc-shaped bucket 7 is installed on the sliding sleeve 4 via a power drive assembly. An adjusting rod 11 is installed on the side-fixed sliding rods 3 via a position adjustment fixing assembly. An arc-shaped adapter block 12 is fixedly installed at the end of the adjusting rod 11. A linkage assembly is provided between the adjusting rod 11 and the sliding sleeve 4. When the sampling placement sleeve 1 is passed through the corn plant and contacts the ground, the adjusting rod 11 is moved. At this time, the arc-shaped adapter block 12 will contact the corn plant stem. Since the thickness of the corn plant stem varies, the root extension position at the bottom varies. The thicker the stem, the wider the root extension range, requiring a larger sampling range.

[0016] Furthermore, the position adjustment and fixing assembly includes a strip hole 8 on the top of the sliding sleeve 4, a fixing rod 9 fixedly installed on the top of the side fixing slide rod 3, the top of the fixing rod 9 movably passing through the strip hole 8, an adjusting sleeve 10 fixedly installed on the top of the fixing rod 9, an adjusting rod 11 movably installed inside the adjusting sleeve 10, a positioning bolt 14 provided on the adjusting sleeve 10, and multiple positioning screw grooves 13 opened on the top of the adjusting rod 11, one end of the positioning bolt 14 being threaded into the positioning screw groove 13, and the positioning bolt 14 being threaded into a corresponding positioning screw groove 13. The positioning screw grooves 13 are arranged relatively densely, which can fix the position of the adjusting rod 11 during fine adjustment.

[0017] Furthermore, the linkage component includes an adjusting drive rod 15 rotatably installed between the sliding sleeve 4 and the adjusting rod 11. The arc-shaped adapter block 12 contacts the corn plant stalk. At this time, under the linkage action of the adjusting drive rod 15, the sliding sleeve 4 is driven to slide on the side fixed slide rod 3, which can automatically adjust the position of the arc-shaped bucket 7, thereby quickly adjusting the sampling range.

[0018] Furthermore, the power drive assembly includes a fixed frame 5 fixedly installed at the end of the sliding sleeve 4. A telescopic cylinder 6 is installed on the fixed frame 5. The output end of the telescopic cylinder 6 is fixedly connected to the top of the arc-shaped bucket 7. The arc-shaped bucket 7 is set at an inward tilt. Multiple arc-shaped buckets 7 are arranged to form a ring. Multiple standing counterweight plates 16 are fixedly installed on the side of the sampling placement sleeve 1. When the telescopic cylinder 6 is started, it drives the arc-shaped bucket 7 to move down. At this time, the worker can stand on the standing counterweight plate 16. By increasing the counterweight, it is easy for the arc-shaped bucket 7 to extend into the soil for digging and sampling. After digging, the entire sampling placement sleeve 1 is lifted up, so that the corn plants can be sampled in situ. During the sampling process, in order to ensure the accuracy of the sampling, samples are taken from plants in different locations in the field.

[0019] In use: During the production process of corn plants, in order to facilitate the observation of root growth at different stages, it is necessary to sample the roots of the corn plants for experiments. The sampling sleeve 1 is inserted through the corn plant, and the adjusting rod 11 moves to make the arc-shaped adapter block 12 contact the corn plant stem. According to the different thicknesses of the corn plant stem, the position of the arc-shaped bucket 7 can be automatically adjusted under the linkage of the adjusting rod 15, so that the sampling range can be quickly adjusted. The telescopic cylinder 6 is activated to drive the arc-shaped bucket 7 to move down. At this time, the worker can stand on the standing counterweight plate 16. By adding counterweight, it is easier for the arc-shaped bucket 7 to extend into the soil for digging and sampling. During the sampling process, in order to ensure the accuracy of the sampling, samples are taken from different locations of the plants in the field. It is convenient to use.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
