Eco-friendly Biodegradable Mulching Sheet and Manufacturing Method Thereof

摘要

The present invention relates to an eco-friendly biodegradable pulp mulching paper and a manufacturing method thereof. The eco-friendly biodegradable pulp mulching paper, which has a structure that a mixture is attached to a pulp base paper, comprises: a pulp base paper weighed in 40 to 60 g/m^2, manufactured by a wood mechanical pulp process; a mixed water of 400 liters for mixing a mixture attached to the pulp base paper; a fermented soybean of 2 to 5 kg, containing Bacillus subtilis introduced to the mixed water for biodegradation; a treacle of 2 to 5 kg, introduced to the mixed water for feed of the Bacillus subtilis; charcoal powder of 30 to 50 kg, mixed with the mixed water for controlling the transmittance amount of sunlight and humidity; an adhesive mixture of 80 to 120 kg, having a carbohydrate-based adhesive and an albumin adhesive mixed in a ratio of 1 : 3 to 3 : 1 with the mixed water to be introduced; a CMC binder of 0.8 to 1.2 kg, introduced to the mixed water to bind a composition, and dissolved in water of 20 L to increase viscosity; a cellulose dispersing agent of 80 to 120 g, introduced to the mixed water; and boron and zinc separately having 250 to 500 g, introduced to the mixed water as a trace element fertilizer. The eco-friendly biodegradable pulp mulching paper is produced by selecting the amount of mixture components to be suitable for an environment or soil condition in which crop grows, or the kind of the crop to be attached to the pulp base paper (200) in a uniform thickness to have a dry weight of 4 to 8 g/m^2.
