초록

작물의 멀칭재배에 활용이 가능한 생분해성 비닐의 생분해 특성과 작물 재배에 따른 특성 변이를 검정한 결과는 다음과 같다. 1. 천연고분자인 벼 부산물(왕겨와 쌀겨)을 이용하여 상업적으로 이용이 가능하고 생분해가 가능한 멀칭 비닐을 제조하였다. 2. 생분해성 멀칭 비닐의 특성 검정을 위한 표준 생분해도 측정결과 셀룰로오스 대비 75%의 생분해가 되어 친환경 기준을 충족함을 확인하였다. 3. 생분해성 멀칭 비닐의 기계적인 특성은 기존 멀칭비닐과 비교해서 인장강도와 인장력에서 우수함을 보였고, 파단점 비후 비교에서도 생분해성 비닐은 지속적인 힘을 유지시켜야 늘어나는 특성을 보였다. 4. 작물을 대상으로한 시험에서 기계화도 가능하며, 인장강도와 인장력을 통한 분해력 비교에서 작물에 따라 시간이 지남에 따라 인장강도와 인장력에 차이를 보임을 관찰할 수 있었고, 작물의 토양 피복도가 생분해에 영향을 미침을 확인하였다.

The main challenges for the development of agricultural bio-degradable mulching film concern the degradation during the lifetime of cultivated crops. A set of rice by-product (rice-hull and rice-bran) based bio-degradable mulching films was developed and tested, following the measurement of standard bio-degradability rate and adaptability in a large scale field experiment. The standard bio-degradability of bio-film passed the KS (Korea standard) regulation. The result of mechanical analysis of bio-degradable mulching film presented a higher mechanical strength and elongation rate compared with polyethylene film. In addition, bio-film could be degraded into fragments within 4 months under the field condition of several upland crops. Bio-degradable mulching film indicated great potential as a new source of agricultural bio-degradable material.
