Abstract：There are electrical differences between the shallow buried bamboo shoots and the soil layer in the growing area, which lays a rock physics foundation for the electric exploration to detect the growth position and size of the winter bamboo shoots. Parallel electric numerical simulation tests of bamboo shoots were carried out with two different observation systems: the Union Jack shape and the circle shape. The results showed that it was feasible to use the parallel electric method to detect the spatial spreading position of winter bamboo shoots above them based on the two observation systems, and the detection effect of the Union Jack shape observation system was better. The effective detection depth was about 0. 30 m, and the detection effect was especially significant for winter bamboo shoots with a buried depth of about 0. 20 m. The field tests fully verified the detection effect of parallel electrical method of the Union Jack shape observation system on winter bamboo shoots.This study could provide a new method for the root system exploration of winter bamboo shoots.
