초록

본 연구는 기존 채소 정식기를 활용하여 기계화율이 낮은 종실용 들깨를 대상으로 육묘 기계정식 재배 시 적합한 상토, 트레이, 육묘일수를 설정하고자 2017년부터 2018년까지 2년간 수행하였으며, 주요 결과를 요약하면 다음과 같다. 1. 들깨의 지상부 생육은 수도용 경량인 R1 상토가 가장 좋았으며, 주요 성분비는 질석(Vermiculite) 41.0%, 코코피트(Cocopeat) 31.0%, 황토(Red-yellow soil) 20.0%, 피트모스(Peatmoss) 5.7% 등을 포함하고 있다. 2. 묘를 직접 뽑아서 공급하는 반자동 정식기를 사용할 경우 128~220공 트레이와 수도용 경량 상토에서 23일 육묘가 적정한 것으로 판단된다. 3. 128공 전용트레이를 사용하는 꽂아내기식 정식기는 매트형성과 초장을 고려하면 수도용 경량 상토에서 23일 정도 육묘가 적정한 것으로 나타났다. 4. 220공 전용트레이를 사용하는 밀어내기식 정식기는 줄기를 잡고 정식하기 때문에 초장이 15 cm 이상 되어야 가능하다. 220공에서 15 cm 이상으로 육묘하는 것이 어려워 기계정식에는 부적정한 것으로 판단된다.

The purpose of this study was to analyze the growth characteristics of perilla according to the materials of the seedbed for the development of seedling plug technology suitable for the mechanical transplantation of perilla. Perilla (Perilla frutescens var. japonica Hara) cultivars Deulsaem and Sodam were used in this experiment. The composition ratios of 170 products from 16 companies published in the 'Korean Association of Seedbed Media' homepage were compared according to usage and type, and 11 products that corresponded to the average were selected. The seedbed was classified according to the seedbed for paddy rice as light-weight, semi-weight, and weight, and based on the seedbed for horticulture, as light-weight and ultra-light. The seedlings were placed in 72-cell (semi-automatic), 128-cell (automatic) and 220-cell (automatic) plug trays. We selected 2 light-weight seedbeds of paddy rice and 2 light-weight seedbeds of horticultural products with the highest plant growth. We analyzed plant height and mat formation of the perilla roots. Results showed that the perilla height and mat formation were the best in light-weight seedbeds of paddy rice (product R1). Therefore, light-weight seedbeds of rice (product R1) were suitable for perilla plant transplantation. The estimated major components were vermiculite 41.0%, cocopeat 31.0%, peat moss 5.7%, and red-yellow soil 20.0%. The mechanical transplantation of perilla significantly boosts plant growth and reduces sowing and thinning efforts. However, continuous evaluation of newly introduced, commercial seedbeds is needed.
