Irrigation Method with Semi Permeable Membrane, Irrigation Container and Irrigation System Made of Semi Permeable Membrane and Their Application

摘要

An irrigation method with semi permeable membrane includes the steps: making into long irrigation time container (15) or long irrigation time container irrigation system made of semi permeable membrane for irrigation in the field of framing and forestry; repeatedly or continuously adding water to the long irrigation time container or long irrigation time container irrigation. It makes use of the physical character of semi permeable membrane, and bases the principle of the potential energy of two sides of semi permeable membrane driving water to directional move. The outside wall (1) of the long irrigation time container is made of semi permeable membrane by heating, mechanical sealing or blowing molding, and water inlet (4) is formed on said outside wall. Multiple of the long irrigation time containers are connected by water feeding pipeline formed by main pipe-line (12) and sub-pipelines (13) attached to main pipe-line, to form network long irrigation time container irrigation system. Each long irrigation system time container of the system corresponds to a water supply head. The long irrigation time container with snap sealing (2, 3) that can be opened and closed repeatedly is applied in salina to clear away salt and alkali.
