MULCHING SHEET DERIVED FROM STRAW

摘要

The present invention relates to a new type of agricultural perforated or airless mulching sheet derived from straw, which according to the present invention has a thickness of 0.3 to 6.0 mm, a basis weight of 60 to 1200 g / m ² , and a dry state. A porous mulching sheet having a tear strength in the dry state of 15 to 80 kg / cm and a tear strength in the wet state of 5 to 35 kg / cm is provided, optionally at least on one surface of the solvent. 1 to 6 g / m 2 (thickness 0.3 to 1.8 μm) based on the dilution resin solution may include a thin film coating layer of resin, and may optionally support fertilizer and / or pesticide components, and the mulching sheet of the present invention may be straw As it is manufactured by recycling, it is environmentally friendly and biodegradable, so it does not need to be collected by separate labors. It has the advantage that it is easy to impart functionality, such as to support fertilizers and / or pesticides, and can greatly contribute to solving the rural environmental problems that are becoming serious by reducing the amount of the conventional polyethylene mulching film.
