Abstract: Gansu zokor is a kind of underground rodent widely distributed in the Loess Plateau. It does not hibernate in winter and summer, and has a wide range of feeding habits. However, its active feeding range is relatively fixed. In this paper, the principle of TBS system, which is widely used in the prevention and control of ground rodents in farmland, is used to explore the effect and feasibility of fence in the prevention and control of Gansu zokor. The results showed that each fence could reduce the damage of Gansu zokor to potato in the treatment area and increase the yield of potato. The closed bamboo underground fence had a good blocking effect on Gansu zokor, which could completely block the feeding damage of Gansu zokor in the treatment area, but the metal net underground fence could not completely block the migration of Gansu zokor. There was no Gansu zokor moved into the closed bamboo underground fence treatment area, and the damage rate was 0%. The average damage area in the open metal net underground fence with trapping holes treatment area was 1.8 m2, and the damage rate was 7.2%, and the trapping holes could not trap Gansu zokor. The average damage area in the open metal mesh underground fence treatment area was 2.47 m2, and the damage rate is 9.87%. The yield of potato increased by 33.06%, 28.54% and 19.73%, respectively. This study provides a very high guiding significance for exploring the fence system for the prevention and control of Gansu zokor.
