The sizes of the inner and outer spiral blades are matched, and the positions of the inner and outer penetrating holes formed on the blades are consistent. The central inner cylinder is communicated with an external liquid storage tank 3, and a control switch is arranged on a communicated pipeline and used for controlling whether liquid in the liquid storage tank flows into the central inner cylinder or not. The installation of the device is completed by placing the central inner cylinder 201 in the central outer cylinder 101 and the inner helical blade 202 in the outer helical blade 102.

During or after the excavation of the planting pit by using the device provided by the invention is finished, liquid can be injected or infiltrated into the planting pit, and the method specifically comprises the following steps: when the cylinder body is rotated, particularly when the inner cylinder body is rotated to enable the inner and outer permeation holes on the inner and outer spiral blades to be mutually overlapped, a control switch on a pipeline is opened, liquid in the liquid storage tank 3 flows through the central inner cylinder 201, the inner permeation through holes 203 and the outer permeation holes 103, and then a reinforcing layer is formed after the liquid permeates into the planting pits. The liquid is usually a microorganism-treated liquid, and may be, for example, an aerobic microorganism-treated liquid or a facultative anaerobic microorganism-treated liquid. After the liquid injection or the liquid seepage is completed, the control switch is closed, and when the inner and outer permeation holes are staggered by rotating the cylinder body, the liquid in the liquid storage tank does not flow out any more, as shown in fig. 3(a) and 3 (b).
