Abstract

The effect of biodegradable mulching film on the growth and development of garlic were investigated in order to develop eco-friendly weed control techniques. The treatments included biodegradable film (Bio-De) and black (Black-PE), green (Green-PE), transparent (Trans-PE) polyethylene mulching films. Non-mulched, bare soil (Non-mulching) was used as a control. Light transmittance value among tested mulching films was the highest in Trans-PE (86.1%) followed by Bio-DE and Green-PE, and the lowest value was observed for the Black-PE (1.1%). All mulching films without exclusion elevated soil temperature, especially Trans-PE and Bio-DE compared to bare soil. Plant height and mean bulb weight were increased due to mulching films with the highest values observed for Trans-PE and Bio-DE treatments. After seven months of field application there were no significant degradation signs on PE plastic films, whereas it was easy to see horizontal cracks on the Bio-DE film surface after five month of usage.

난지형 마늘 재배시 잡초발생 억제와 친환경 방제기술을 개발하기 위하여 생분해성 필름을 이용한 멀칭재배효과를 구명하고자 수행하였다. 멀칭 필름의 투광률은 흑색 PE 필름은 1.1%, 녹색 PE 필름은 26.1%, 투명 PE 필름은 86.1%, 생분해성 필름은 75.4%로 흑색 PE 필름의 경우 대부분의 광이 투과되지 못하였지만 녹색 PE 필름은 일부 광이 투과되었고 생분해성 필름과 투명 PE 필름은 투광률이 높았다. 지온은 무멀칭구에 비해 멀칭구가 높았고 투명 PE 필름, 생분해성 필름이 가장 높게 나타났다. 초장과 구중에서도 지온이 높게 유지되었던 멀칭구가 높았고 투명 PE 필름, 생분해성 필름이 가장 높았다. 멀칭재료별 소실상태는 멀칭 7개월까지 비닐 및 부직포멀칭구는 외관상 크게 소실되는 것을 없었으나, 생분해필름은 멀칭 5개월 이후 필름표면에 가로로 미세한 줄이 나타났고 쉽게 찢어지는 것을 볼 수 있었다.
