PROBLEM TO BE SOLVED: To provide a subirrigation system causing no depletion of a permeation function by clogging by utilizing permeation function of soil itself.
SOLUTION: The subirrigation system includes a water-barrier member 16 for keeping the water content of soil in a cultivation land 100 in a proper state for the growth of a plant. The water-barrier member 16 is formed into a top-opened container shape and has a water reserving function. The inside of the water-barrier member 16 is fed with water from a water tank via a feed water pipe, thereby forming a soil portion 26 in a gravity water state. The gravity water in the water-barrier member 16 has its water level 28 administered properly to a desired level by a water level administrator disposed in the feed water pipe. The gravity water, as administered to the desired water level, in the water-barrier member 16 is suitably sucked up into the soil of the upper layer by the capillary phenomenon. As a result, a soil portion 30 in the capillary water state having the proper water content is formed in the cultivation land 100.
