CAPILLARY ROOT ZONE IRRIGATION SYSTEM

摘要

A capillary system (20) for providing water, nutrient solutions and gases such as air to the root zone of plants. The system uses one or more conduits (10) having perforations (11) spaced apart therealong, with the conduits (10) being held in pockets (14). The pockets (14) are formed with an upper layer (12) of capillary cloth and a lower layer (13) of capillary cloth and/or a water impermeable material. The conduits (10) are provided with a means for connection to a supply of water and the like. In use, the capillary system (20) is buried to an appropriate depth in soil below the plants to be irrigated. The upper layer (12) of capillary cloth is wet by the flow out of the perforations (11) and serves to distribute water evenly to the roots. Fluid flow control means e.g. valve is optionally provided to control flow through the conduits.
