Novel micro-irrigation belt

The utility model relates to a water-saving irrigation component, in particular to a novel micro-irrigation belt, belonging to the improvement of a drip irrigation belt flow channel structure. The inner wall surfaces at the lower edge of the pipe wall of the micro-irrigation belt are fixedly connected through ascending weld lines which are longitudinally arranged and descending weld lines which are longitudinally arranged in parallel to the ascending weld lines; a cavity channel is formed by the pipe walls of the front micro-irrigation belt and the rear micro-irrigation belt between the ascending weld lines and the descending weld lines, the ascending weld lines and the descending weld lines; the pipe walls at the two sides of the cavity channel are fixedly connected through weld point arrays which are evenly distributed and longitudinally arranged; a micro-irrigation flow channel is formed in the cavity channel by the weld point arrays consisting of weld points; two adjacent rows of weld points are arranged
