In the watering tank, the water in the water collecting container 3 can be transported to the drip strip 2, and since the water collecting container 3 is located above the height space of the drip strip 2, the controller only needs to open the water supply solenoid valve 21, and then The use of gravity self-flow water supply, thereby reducing power consumption. Wherein, in the infrastructure construction process, the annular water blocking enclosure 4 may be an annular water retaining plate, a ring-shaped plastic film, an annular water retaining band or an annular soil retaining wall, and the performance entity of the annular water blocking enclosure 4 in this embodiment No restrictions. In addition, the height dimension of the annular water blocking enclosure 4 in this embodiment is determined according to the growth depth of the root type of the local weed species, so as to ensure that the depth of the surface dry soil layer does not meet the requirements of weed growth, and the drip irrigation belt The depth of burial depends on the depth of growth of the crop roots, and the growth depth of the crop roots is greater than the depth of weed roots, so that the drip irrigation belt 2 only supplies water to the crops, ensuring that the soil layer remains arid at a specific depth on the surface.
