[0038] Embodiment 2:

[0039] On the basis of embodiment 1, please refer to Figure 2 、 7 The inner wall of the communication part between the extrusion bag 6 and the liquid passage pipe 10 is further fixedly connected with a self-pressing sealing member 11, the self-pressing sealing member 11 comprises a fixed seat 1101, the middle part of the inner wall of the fixed seat 1101 is provided with a flow channel, and the inner wall of the flow channel is fixedly connected with two silica gel sealing balls 1102 in abutment with each other, before the expansion pushing rod 402 is pressed downward by the filling starting member 5, the two silica gel sealing balls 1102 are tightly extruded together by the elastic force of the silica gel sealing balls 1102, so as to play a sealing role, and after the expansion pushing rod 402 is pressed downward by the filling starting member 5, the expansion force of the expansion pushing rod 402 compresses the extrusion bag 6 to make the biological fertilizer 601 overcome the silica gel sealing balls 1102 and extrude into the soil in the cultivation cylinder 2, so that the cultivation object can absorb;
