System and Method for Irrigation

摘要

A method for subsurface irrigation having the steps of; providing one or more hydrophobic porous uncoated tubes having a hydro head (HH), locating the tubes with at least a portion of their length within the rhizosphere of plants to be irrigated, and passing an aqueous irrigation liquid into the tubes during the growth phase of the plants to be irrigated at an applied pressure at or below HH. The tubes may be located in the proximity of seeds which become the plants to be irrigated following their germination. In this embodiment, aqueous irrigation fluid is passed into the tubes during a germination phase of the seeds at an applied pressure that is at least 10% higher than the applied pressure during the growth phase of the plants.

1. A method for subsurface irrigation of plants or seeds comprising the steps of;
i. providing one or more porous tubes that are not coated with a hydrophilic material into which an aqueous irrigation fluid is supplied to one or more of the tubes, wherein the tubes comprise materials having a hydrohead (HH); ii. locating the tubes with at least a portion of their length in the proximity of a plurality of plants to be irrigated that are in their growth phase; iii. passing the aqueous irrigation liquid into the tubes during said growth phase of the plants to be irrigated, at an applied pressure (Pgrowth) at or below HH;wherein the tubes are in fluid contact with each other and are configured in a configuration such that the aqueous irrigation fluid enters the tube configuration and is pressurized therein such that the minimum length of tubing between the irrigation fluid entry point and at least one of the plants to be watered is 61 meters and the HH of at least a portion of the one or more tubes is at least 100 cmwc.
