PURPOSE: A mulching mat improved in both coating characteristics on a resin laminated surface and hydrophilic characteristics on a soil coated surface to improve rice transplanter workability and a control value against weeds is provided. Therefore, it permits easy application to paddy fields and ordinary fields and is biodegradable within several months, thus to generate no environmental pollution and to increase mechanical workability. CONSTITUTION: Resin obtained by copolymerizing or blending thermoplastic resin having total or partial degradation properties with a hydrophilic compound of the formula of H-(O-R1)L-OH is coated on paper and then wound. In formula, L is a repeating unit, R1 is aliphatic hydrocarbon containing 2 carbons. The degradable thermoplastic resin is natural material and recycled pulp of starch, cellulose, polyhydroxybutylate and polyhydroxyvaleate; and biodegradable aliphatic polyesters, polylactic acid, polybutyleneadipate-co-terephthalate, polyester urethane copolymer, a photodecomposable resin containing a photocatalyst in polyethylene or a mixture containing two or more of them. 본 발명은 이앙기 작업성과 잡초 방제가를 향상시키기 위해 수지 적층면에 대한 코팅특성과 토양 피복면에 대한 친수특성을 동시에 개선시킨 농업용 매트에 관한 것으로, 본 발명의 멀칭매트는 이앙 및 직파용 논 토양 적용이 모두 용이하며 특정한 크기의 롤 형태로 표준화시켜 농업의 기계적 작업성과 멀칭성 그리고 운반성을 크게 향상시킨 것이며, 또한 멀칭매트로써 기본적인 잡초방제 효과와 지온상승 효과를 동시에 나타내고, 멀칭후 수개월 이내에 자연 생분해됨으로써 환경오염이 없는 농업을 제공할 수 있고, 제초제와 같은 고독성 농약을 사용하지 않고 농작물을 재배할 수 있으므로 친환경 농산물 생산에 매우 적합한 농업용 소재이다.
