| 摘要 |
The present invention refers to a novel irrigation system with plastic film applied in furrows for collecting rain water or water irrigated by irrigation systems simulating rain; the invention is characterised in that it comprises a plastic film installed in valleys located between furrows where an amount of soil has been previously poured from the side portions of adjacent furrows, thus forming a hump for supporting the film on the furrows; the hump forms a convex channel useful for collecting rain or irrigated water and leading it to the high portion close to the bulk of the adjacent furrows, directly to the root system of crop plants; the film is installed in a manual or mechanical manner, the side portions of the plastic film being buried at pressure in the flanks of the adjacent furrows, said side portions being therefore buried in order to be safely placed in the soil; the plastic film covers the whole part of the valleys and part of the furrow flanks, the crop plants being subs equently located on the bulk of the furrows.
