| 摘要 |
An irrigating device formed from an absorbent product, such as a polymeric pulp or hydrophilic textile contained within a filtering envelope, such as a woven, knitted or non-woven fabric. The device is placed in the ground in communication with a source of water which may be above or below ground. The irrigation device provides for a uniform rate of irrigation of the soil in which it is placed, requires less water than conventional irrigation devices providing the same overall coverage, and is not subject to dogging or blockage, as with conventional irrigation devices.
