요약 : 최근 산불발생지 복원, 탄소중립을 위한 대규모 조림 등으로 용기묘의 효율적인 대량 생산의 중요성이 인식되고 있다. 용기묘 양묘 시 포트 상단에 이끼류가 발생하여 “moss cap”을 형성하고 관수와 시비를 차단하여 묘목품질과 생산효율을 감소시켜 문제가 되고 있다. 기존의 이끼제거제는 화학제품으로 묘목 약해와 환경오염의 우려가 있다. 따라서 본 연구는 친환경 소재를 이용한 이끼제거제 개발을 목적으로 하였다. 13가지 친환경 물질을 선정하여 예비실험을 진행하였고 선발된 6가지 물질을 이끼를 이식한 상수리나무 1-0묘에 처리하여 이끼제거율과 재발율, 묘목약해, 생장변화, 토양특성변화, 토양 잔류농약 검사를 실시하였다. 묘목약해는 육안판별, 전해질 누출법, DAB Staining법으로 피해를 진단하였다. Terpinyl acetate 등은 상수리나무 양묘에서 이끼제거율이 100%를 나타내었고, 묘목 생장과 약해, 토양에 거의 영향을 미치지 않았다. 이상의 결과는 친환경 이끼제거제의 개발 및 고품질 용기묘 생산에 기여할 것이다.

Abstract : Recently, the importance of efficient mass production of container seedlings has been recognized due to the restoration of forest fire sites and large-scale afforestation for carbon neutrality. When growing container seedlings, moss grows on the top of the pot, forming a “moss cap” and blocking irrigation and fertilization, reducing seedling quality and production efficiency, which is a problem. Existing moss removers are chemical products and have the potential to damage seedlings and pollute the environment. Therefore, this study aimed to develop a moss remover using eco-friendly materials. A preliminary experiment was conducted by selecting 13 eco-friendly materials, and 6 selected materials were treated in 1-0 oak trees with moss transplanted to test moss removal rates, recurrence rates, seedling weaknesses, growth changes, soil characteristics changes, and soil residual pesticides. Damage to seedlings was diagnosed using visual discrimination, the electrolyte leakage method, and the DAB staining method. Terpinyl acetate showed a 100% moss removal rate in oak tree nurseries and had little effect on seedling growth and soil. The above results will contribute to developing eco-friendly moss removers and producing high-quality container seedlings.
