In the embodiment, the adhesive is carboxymethyl cellulose aqueous solution, and the application amount of the carboxymethyl cellulose relative to the plant residue is 0.2-0.6g 8729kg-1.
Specifically, the carboxymethyl cellulose aqueous solution has the characteristics of good thickening, suspension, adhesion, water retention and the like, the CMC is added into the pressing plate, so that the CMC can combine with water in soil to prevent the water from evaporating, and the water is released into the soil again along with the degradation of the CMC by microorganisms.
In this embodiment, the partition plates 4 are respectively located at one side of the waterside plants 1, the shallow water regions 2 and the deep water regions 3, the surface of the partition plate 4 at one side of the waterside plants 1 is provided with a plurality of water permeable holes 41 which are arranged in a straight line, the thickness of the partition plate 4 at one side of the waterside plants 1, the shallow water regions 2 and the deep water regions 3 is gradually increased, and the degradation efficiency of the partition plate 4 in the deep water regions is reduced by using the partition plate 4 with large thickness.
In this embodiment, the surface of the protective film 5 is provided with planting holes 52, the protective film 5 can be made by three methods, i.e., an ultrasonic fusion welding packaging machine, a hot-press sealing method or a sewing method, which integrates bag making and material feeding functions, continuously, and the like, the nutrient particles 51 are positioned between the two layers of PLA corn fiber cloth, and the nutrient particles 51 are slow-release granular fertilizers.
Specifically, the double-layer PLA corn fiber cloth is laminated and combined by ultrasonic fusion welding, hot-press sealing or sewing, and the nutrient particles 51 are wrapped, so that the slow-release particles can be slowly released in the protective film 5 for plants to grow and absorb, and soil conservation and fertilizer release are realized.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
