膜孔灌 使用水力自动定量的田间均衡分水计量装置,把水均等地分到各灌水畦,然后利用地膜输水,通过放苗孔和专用灌水孔给作物分水计量的灌水方法,叫做膜孔灌。为消除膜侧旁渗,需要在每幅地膜的两侧,利用膜间空地筑起畦埂,并把膜边上翘埋入畦埂中,使水流集中在膜槽内流动,在流动过程中实现均匀灌水。新疆的膜孔灌有三种形式,如图所示。 Membrane hole irrigation using hydraulic automatic quantitative field equilibrium water metering device, the water equally divided into the irrigation 畦, and then the use of plastic membrane water, through the hole and special irrigation holes to the crop water metering irrigation method, called membrane Hole irrigation. In order to eliminate the membrane side of the infiltration, the need for film on both sides of each film, the use of space between the membrane erected 畦 埂, and the film upside down buried 畦 埂 in, so that the flow of water concentrated in the membrane flow in the flow process Achieve even irrigation. There are three forms of film hole irrigation in Xinjiang, as shown in the figure.
