ABSTRACT:
Disclosed are an even-irrigation apparatus for an underground root zone and an even-irrigation method using the same for evenly supplying water into the root zone of a variety of crops. The even-irrigation apparatus includes a plurality of irrigators buried in the entire underground root zone, to directly and evenly supply water into the root zone. Once water is introduced into a pressure-reduction valve after passing through a main pipe, limb pipe and capillary pipe connected in sequence, the water is supplied to the irrigators by way of a plurality of diverged-capillary pipes. With this even-irrigation of water, unnecessary consumption of water due to adsorption of the water into the surrounding soil except for the root zone is minimized, enabling effective irrigation of water and even growth of roots of crops. Further, even nutrition throughout the roots enables balanced growth of crops.
