[0010] Reference Figure 1 Figure 2 Figure 3 Figure 4 The aforementioned experimental device for identifying the resistance of peanut hairy roots to root rot pathogens includes an experimental chamber 1, a sealing cover 2, a locking device 3, a fungicide injection device 4, a fixed pad 5, a movable insert plate 6, and a fixed partition plate 7. The device is characterized in that: the sealing cover 2 is rotatably connected to the middle of the rear surface of the experimental chamber 1; the sealing cover 2 is connected to the upper surface of the experimental chamber 1 by a locking device 3; several fungicide injection devices 4 are evenly distributed horizontally at the front of the upper surface of the experimental chamber 1; and the front of the lower surface of the experimental chamber 1... A fixed pad 5 is connected in the middle. A movable insert plate 6 is inserted in the middle of the front edge of the upper surface of the experimental box 1. Several fixed partitions 7 are evenly distributed horizontally on the lower surface inside the experimental box 1. The experimental box 1 includes an outer box 1-1, threaded holes 1-2, notches 1-3, and slots 1-4. Several threaded holes 1-2 are evenly distributed horizontally in the middle of the front edge of the upper surface of the outer box 1-1. Several notches 1-3 are evenly distributed horizontally in the front edge of the upper surface of the outer box 1-1. Inside the outer box 1-1... The lower surface and the front edges of the left and right side surfaces are each provided with a slot 1-4. The movable insert plate 6 is inserted into the slot 1-4. The movable insert plate 6 is made of glass. The locking device 3 includes a rotating plate 3-1, a hook 3-2, a locking post 3-3, and a rotating shaft 3-4. The hook 3-2 is connected to the middle of the front surface of the rotating plate 3-1. The locking post 3-3 is inserted into the center of the upper surface of the hook 3-2. The rotating shaft 3-4 is connected to the middle of the rear of the lower surface of the rotating plate 3-1. The rotating shaft 3-4 is rotatably inserted into the locking device. On the upper surface of the cover plate 2, the clamping post 3-3 is connected to the upper surface of the outer box 1-1. The inoculation device 4 includes a threaded tube 4-1, a pull strap 4-2, a chuck 4-3, and a rubber plug 4-4. The pull strap 4-2 is connected to the upper part of the side surface of the threaded tube 4-1. The chuck 4-3 is connected to the middle of the other end of the pull strap 4-2. The rubber plug 4-4 is connected to the center of the lower surface of the chuck 4-3. The rubber plug 4-4 is inserted into the upper surface of the threaded tube 4-1. The threaded tube 4-1 is inserted into the threaded hole 1-2.
[0011] In use, the staff first places the peanut seedling roots inside the front surface of the outer box 1-1 on the experimental chamber 1, while simultaneously securing the stems and roots within the notch 1-3. The partition 7 is then fixed to separate the roots of each peanut seedling. Next, the movable insert 6 is inserted into the slot 1-4 to seal the front surface of the outer box 1-1. The staff then opens the sealing cover 2 and fills the outer box 1-1 with soil. After each compartment is filled, the sealing cover 6 is placed on the rear surface of the outer box 1-1. The rotating plate 3-1 on the locking device 3 is then rotated on the rotating shaft 3-4. Finally, the hook 3-2 is inserted into the locking post 3-3 to secure the seal. After the cover plate 6 is fixed, the staff separates the chuck 4-3 from the threaded tube 4-1 on the inoculation device 4 and pulls the rubber stopper 4-4 out of the threaded tube 4-1. Since the chuck 4-3 and the threaded tube 4-1 are connected by the pull strap 4-2, the chuck 4-3 will not be lost. Then, the root rot pathogen is injected into the outer box 1-1 through the threaded tube 4-1. Then, the rubber stopper 4-4 and the chuck 4-3 are inserted into the threaded tube 4-1. Then, the outer box 1-1 is tilted forward by the fixing pad 5 so that the root rot pathogen can flow quickly to the roots of the peanut seedlings. Finally, the staff observes and records the experimental effect through the movable insert plate 6.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
