[0040] In an embodiment of the present invention, before sowing corn, select the positions to be set between the ridges or between the corn rows in each test plot for marking. Each plot is repeated four times, and four positions are determined to install the device of the present invention. A total of 40 sets of the device of the present invention are installed in 10 plots. At each position, dig a soil pit according to the size of the root window 1, place the root window 1 into the dug soil pit, make the observation window 7 close to the soil surface, fill some of the dug soil into the gap between the soil and the non-observation surface 13 and compact it to prevent the root window 1 from shaking. Then place the top cover 2 on the top of the root window 1, and the four sides of the top cover 2 should exceed the top range of the root window 1 to prevent rainwater from impacting the contact surface between the device and the soil. After the installed root window 1 is stabilized for a period of time, sow the seeds at a position 0.03 m away from the outside of the observation surface 13 on the corn planting row.
[0041] When it is necessary to observe the root system, at a certain point, first remove the top cover 2, place the movable inner shell 3 inside the root window 1, and then connect the movable fixer 4 with the second connector 12 to the first connector 11. In this embodiment, it is to hang the in-vehicle mobile phone holder with a sub-button on the first mother button; then wirelessly connect the controller 9 to the image acquisition device 8, and fix the image acquisition device 8 on the movable fixer 4.
