[0018] Wherein, a solenoid valve 7 is provided between the main pipeline 3 and the branch pipeline 4;

[0019] The branch pipe 4 is connected to the capillary pipe 5 via a dripper 8 .

[0020] The water storage container 1 involved in this embodiment is connected to a water source and is made of plastic, which is low in cost. The water storage capacity is selected according to the number of crops to be irrigated, which is flexible and practical.

[0021] The switch 2 is used to control the on and off of the main pipeline 3;

[0022] The main pipe 3, the branch pipe 4 and the capillary pipe 5 are all made of plastic, the cost is controllable, and the pipe diameter and number are selected according to the number of crops to be irrigated;

[0023] The Dijian 6 is a commercially available product, priced at about RMB 1 per piece. It adopts a labyrinth long flow channel arrow handle structure, a diaphragm-type steady flow, and the drip irrigation height can be adjusted to adapt to soilless cultivation containers of different heights.

[0024] The solenoid valve 7 is used to control the on-off of the branch pipeline 4;

[0025] The main structure of the dripper 8 includes a truncated cone-shaped base 81 and a branch pipe end 82 and a capillary end 83 arranged at both ends thereof. The branch pipe end 82 is connected to the branch pipe 4 through a chamfer, and the capillary end 83 is connected to the capillary pipe 5 through a chamfer.

The size matches the branch pipe 4 and the capillary pipe 5.

[0026] The soilless cultivation automatic drip irrigation device of this embodiment is suitable for hanging vine cultivation of watermelon or melon. When used:

[0027] Connect the solenoid valve 7 provided on each branch pipe 4 to the substrate humidity sensor provided at the bottom of a certain cultivation pot under each branch pipe 4 (i.e., among the several cultivation pots under each branch pipe 4, only one cultivation pot is provided with a substrate humidity sensor, and the solenoid valve 7 corresponds to the substrate humidity sensor one by one);
