<p>The invention relates to a pipe with valve for controlling water flow, seeping irrigator and a method for controlling water flow thereof. The pipe with valve is provided with outer layer (11) and core (12) that is formed of porous medium (121) or capillary bundle (12) for acting as capillary. The orifice diameter of the medium (121) or the capillary bundle (12) is in the range of 0.1 to 200 micron and the length of the pipe is 100 times of the orifice diameter. Water flow, which is influenced by the environmental pressure, can be accurately controlled in such a range that the crops are automatically irrigated with fixing water flow.</p> |
