[0002] Adult Populus euphratica has a well-developed root system, especially the horizontal lateral roots, which extend in all directions from the 30-60 cm soil layer and can be more than 10 meters long. Cutting the root system of Populus euphratica is a common method to promote the reproduction of root tillers and guide their growth. Studies have shown that cutting the lateral roots of Populus euphratica during a certain growth period can greatly promote the growth of its root system, promote the reproduction ability of Populus euphratica root tillers, and enhance the rate of reproduction and renewal of Populus euphratica.

[0003] There are two main methods of root pruning. One is manual root pruning, which has high labor costs and low work efficiency. The other is to use an excavator to dig and pruned the roots. However, the width of the trench dug by the excavator often exceeds 50 cm, affecting the normal evaporation and water utilization of the poplar. In addition, the excavator's bucket can easily damage the main root system of the poplar.

[0019] The other end of the forearm 4 is hinged to the root cutting mechanism 2, and the two ends of the forearm cylinder 6 are respectively hinged to the upper arm 3 and the forearm 4, and are used to adjust the angle of the forearm 4. The end of the forearm 4 hinged to the root cutting mechanism 2 can be considered as the free end of the excavator arm.

[0020] In order to adjust the angle of the root cutting mechanism 2, an angle adjusting cylinder 7 is also connected between the small arm 4 and the root cutting mechanism 2, and the two ends of the angle adjusting cylinder 7 are respectively hinged to the small arm 4 and the root cutting mechanism 2.

[0021] The root cutting mechanism 2 specifically includes a saw blade drive device, a frame 8 and two cutting blades 9 installed in parallel on the frame 8. The distance between the two cutting blades 9 is 25-35 cm, and the two cutting blades 9 are used to extend into the soil to perform root cutting. Among them, the cutting blade 9 is a circular saw, and the circular saw 9 extends out of the bottom surface of the frame 8 by 55-65 cm to cut the shallow roots.

The fuel gear motor 10 drives the two cutting blades 9 to rotate, and uses oil as energy, which is convenient for field operations. In other embodiments, the saw blade driving device can also be a drive motor, and a battery is used to power the drive motor, but its safety and field operation performance are not as good as the fuel gear motor 10.

[0023] In order to improve the stability of the root cutting mechanism 2 during operation, the fuel gear motor 10 is arranged between the two cutting blades 9, and the fuel gear motor 10 and the fuel tank 11 are arranged on the frame 8 one after the other.
