DETAILED DESCRIPTION

[0040] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0041] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the invention belongs.

[0042] Reference Figure 1-Figure 5 , a recyclable ground film bonded to a drip irrigation tape, comprising:

[0043] A ground film base layer 101, wherein the ground film base layer 101 is an existing ground film layer;

[0044] A plastic net 102, wherein the plastic net 102 is bonded to the ground film layer 101;

[0045] The plastic net 102, the drip irrigation tape 103 is bonded to the other side of the ground film base 101; and

[0046] The plastic net 102 is evenly provided with a plurality of hexagonal holes, and the ground film base layer 101, the plastic net 102 and the drip irrigation tape 103 are bonded by vinyl glue.

[0047] A recyclable ground film bonded to a drip irrigation tape mainly consists of three parts, namely: a ground film base layer 101, a plastic net 102 composed of multiple hexagons, and a general plastic net 102. The above three parts are bonded with vinyl glue, preferably vinyl glue. Cyanoacrylate glue, epoxy resin glue, polyurethane glue, etc. are used as alternative glues based on market feedback and cost.

[0048] For example, the size of a recyclable mulch film bonded to a drip irrigation tape is selected as follows: taking the (2050×0.01) mm mulch film which is the most widely used for cotton planting in Xinjiang as a reference, 3 drip irrigation tapes are laid on 2.05-meter mulch film, and 2 drip irrigation tapes are pasted on 1.2-meter, 1.4-meter, etc. wide mulch films.

[0049] The plastic net 102 is preferably composed of multiple hexagons, because the regular hexagons are evenly stressed and not easy to tear when being pulled during recycling. Squares, rectangles, triangles and other polygons are selected as alternatives according to different environmental needs. The size of the hexagon and the sides (rectangles) that make up the hexagons are selected according to actual needs. The diameter of the hexagon is preferably in the range of 5 cm to 10 cm. The sides (rectangles) of the hexagons are preferably 5 mm to 2 cm wide and 0.1 mm to 5 mm thick. The width and thickness of the sides (rectangles) of the hexagons are other sizes, which can be selected according to different needs.

[0050] It should be noted that some users are slow to accept new things. Moreover, farmers and enterprises that plant on a large scale have problems with losses. They cannot recover their funds and even lose their lives. For general mulch, ordinary mulch, polyethylene and other materials commonly used by farmers are selected. For general drip irrigation tape, ordinary drip irrigation tape, polyethylene and high-pressure polyethylene and other materials are selected. The appearance and material of general mulch and general drip irrigation tape remain unchanged. The material of plastic net is nylon 66, polypropylene, etc. The material of plastic net is the same as that of plastic rolling belt, which can also achieve the effect of leaving as little residue as possible when recycling mulch.

At present, there are many factories that make ordinary mulch and ordinary drip irrigation tapes. Basically, there are factories in every county and even every township, with mature machinery and technology. The production machinery of ordinary mulch and ordinary drip irrigation tapes can be purchased according to needs, and existing equipment does not need to be purchased.
