[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1 to 4, the present utility model provides a technical solution: a device for measuring soil nutrient migration, including: a box body 1, several groups of box bodies 1 are provided, several groups of box bodies 1 are distributed up and down, a box bottom 4 is provided on the surface of the box body 1, nutrient passing holes 5 are opened on the surface of the box bottom 4, several groups of nutrient passing holes 5 are provided, and several groups of nutrient passing holes 5 are evenly distributed. A plugging flange 2 is fixed at the top end of the box body 1, and a plugging groove 3 is opened at the bottom end of the box body 1. The plugging flange 2 has a "return" - shaped structure, the plugging groove 3 has a rectangular groove structure, and the outer ring side length of the plugging flange 2 is equal to the groove side length of the plugging groove 3.

[0021] During actual use, first load different soils into several groups of box bodies 1, then insert the plugging flange 2 provided at the top end of one group of box bodies 1 into the plugging groove 3 opened at the bottom end of another group of box bodies 1, and stack several groups of box bodies 1 in sequence. This process can sort the box bodies 1 containing different soils up and down according to pre - setting to obtain the required simulation environment. Then, add nutrient solution to the top - most group of box bodies 1. The nutrient solution passes through the nutrient passing holes 5 and penetrates the box bottom 4. At the same time, the size of the nutrient passing holes 5 prevents the soils in each group of box bodies 1 from passing through. After standing for a period of time, separate each group of box bodies 1 in sequence and detect the soils in each group of box bodies 1, then the migration efficiency of nutrients at different depths in different soils can be obtained.

[0022] Embodiment 2: On the basis of Embodiment 1, in order to achieve firm assembly and disassembly between each group of box bodies 1, a limiting rod mounting hole 6 is opened on the surface of the box body 1. The limiting rod mounting hole 6 is communicated with the plugging groove 3. A limiting rod 8 is opened on the surface of the plugging flange 2. One end of the limiting rod 8 is movably inserted into the limiting rod mounting hole 6, and the other end of the limiting rod 8 is movably inserted into the limiting hole 7. A sleeve 9 is fixed on the surface of the box body 1. A cavity 10 is provided on the surface of the sleeve 9. The cavity 10 is communicated with the limiting rod mounting hole 6. A spring plate 11 is slidably connected in the cavity 10. The spring plate 11 is fixed on the surface of one end of the limiting rod 8. A spring 12 is provided in the cavity 10. One end of the spring 12 abuts against the inner wall of the cavity 10, and the other end of the spring 12 abuts against the surface of the spring plate 11. A pull rod hole 14 is opened at one end of the sleeve 9 away from the box body 1. The pull rod hole 14 is communicated with the cavity 10. One end of a pull rod 13 is movably inserted into the pull rod hole 14. The other end of the pull rod 13 is fixed on the surface of the spring plate 11 away from the limiting rod 8. A pull ring 15 is fixed at the end of the pull rod 13 away from the spring plate 11.

[0023] When assembling the two sets of boxes 1, pull the pull ring 15 on the upper set of boxes 1 to extend the pull rod 13 from the pull rod hole 14. The pull rod 13 drives the spring plate 11 to move in the cavity 10 opened on the surface of the sleeve 9, so that one end of the limiting rod 8 enters the cavity 10, and the other end is flush with the opening of the limiting rod mounting hole 6. At this time, the spring 12 is compressed. Then, the insertion flange 2 at the top of the lower set of boxes 1 is inserted into the insertion groove 3 at the bottom of the upper set of boxes 1, and the limiting rod mounting hole 6 opened on the surface of the upper box 1 is aligned with the limiting rod mounting hole 6 opened on the surface of the lower box 1. Align the holes 7, then release the pull ring 15. The spring 12 pushes the spring plate 11, which in turn pushes the limiting rod 8, so that one end of the limiting rod 8 is inserted into the limiting hole 7, and the other end of the limiting rod 8 stays in the limiting rod mounting hole 6, thus completing the secure assembly of the two sets of boxes 1. When it is necessary to disassemble the two sets of boxes 1, pull the pull ring 15 again. The pull ring 15 pulls the pull rod 13 out of the pull rod hole 14. The pull rod 13 drives the limiting rod 8 to move in the same direction through the spring plate 11, so that the limiting rod 8 is withdrawn from the limiting hole 7, thus completing the disassembly of the two sets of boxes 1.

[0024] In actual use, first, different soils are filled into several sets of boxes 1. Then, the insertion flange 2 at the top of one set of boxes 1 is inserted into the insertion groove 3 at the bottom of another set of boxes 1. Several sets of boxes 1 are stacked in sequence. This process can be pre-set to arrange the boxes 1 containing different soils vertically to obtain the required simulated environment. Then, nutrient solution is added to the top set of boxes 1. The nutrient solution passes through the nutrient passage hole 5 through the bottom 4 of the box. At the same time, the size of the nutrient passage hole 5 is such that the soil in each set of boxes 1 cannot pass through. After standing for a period of time, the boxes 1 are separated in sequence, and the soil in each set of boxes 1 is tested to obtain the migration efficiency of nutrients at different depths in different soils. When it is necessary to assemble two sets of boxes 1, pull the pull ring 15 on the top set of boxes 1 to make the pull rod 13 extend from the pull rod hole 14. The pull rod 13 drives the spring plate 11 to move in the cavity 10 opened on the surface of the sleeve 9, so that the limit is reached. One end of rod 8 enters cavity 10, and the other end is flush with the opening of the limiting rod mounting hole 6. At this time, spring 12 is compressed. Then, the insertion flange 2 at the top of the lower set of boxes 1 is inserted into the insertion groove 3 at the bottom of the upper set of boxes 1, and the limiting rod mounting hole 6 on the surface of the upper box 1 is aligned with the limiting hole 7 on the surface of the lower box 1. Then, the pull ring 15 is released, and spring 12 pushes spring plate 11, which in turn pushes the limiting rod 8. Push the lever so that one end of the limiting rod 8 is inserted into the limiting hole 7, and the other end of the limiting rod 8 stays in the limiting rod mounting hole 6, thus completing the secure assembly of the two sets of boxes 1. When it is necessary to separate the two sets of boxes 1, pull the pull ring 15 again. The pull ring 15 pulls the pull rod 13 out of the pull rod hole 14. The pull rod 13 drives the limiting rod 8 to move in the same direction through the spring plate 11, thereby causing the limiting rod 8 to exit from the limiting hole 7, thus completing the separation of the two sets of boxes 1.
