The invention provides a well-type
irrigation system. The
system is composed of a well and a water-level controller or a
water supply bottle, wherein the well comprises a
water holding tank (an water-impermeable container), a
water delivery pipeline, a supporting and water-level observation well and a
buoy; the water-level controller comprises a water
inlet valve, a bearing
pipe, a switch valve and a floating body; the bearing
pipe is connected with the
water delivery pipeline; the interior of the bearing
pipe is provided with the floating body located above a water outlet; the floating body is connected with and controls to open and close the water
inlet valve; and the selectable
water supply bottle is composed of a
water bottle, a movable straight pipe part and a height adjuster, is directly and invertedly arranged on the supporting and water-level observation well of the well, and can be used in coordination or mutual replacement with the water-level controller to automatically supply water by utilizing a
pressure control principle. Thus, according to the invention, depending on the principles of
penetration force and communicating pipes, the well is buried in soil; when the
water level in the
water holding tank is no higher than the opening of the
water holding tank, water upward seeps from the bottom part of the water
holding tank; and when the seepage
water level is beyond the opening of the water
holding tank, exterior soil is subjected to
irrigation with water.
