Abstract: The spatial and temporal distribution characteristics of wheat fine roots in the apple wheat intercropping were conducted in the hilly region of TaiHang Mountain. The results showed that the wheat roots system were characterized with densely and sparsely distributed zone vertically, belonging to 0.40 cm and 40.80 cm in soil depth, where the amount of the fine roots accounted for 81.93 % and 18.07% of the total respectively; the horizontal difference of fine roots, characterized with the closer to the tree row and the higher wheat fine root density was more significant with the wheat stage; the filling stage was the turning point in the wheat root growth.
