| Abstract: | Quantity of nematode colony in and between sweet potato caves, between individual plants and lines, in different earth layers in every sample position has been investigated in 5-year-long sweet potato continuous-plant field at different time before and after transplant. Horizontal and vertical distribution characteristics of plant-parasite nematode and non-plant-parasite nematode colony were analyzed, and sampling method for occurrence dynamic study of nematode colony in sweet potato field was put forward. |
