본 실험은 생물반응기를 통해 대량증식된 사계성 딸기 조직배양묘의 적정 순화용기를 선발하기 위해 실시하였다. 순화용기는 플라스틱투명용기, 플러그 트레이, I-포트 및 흑색비닐포트 등 4가지를 사용하였다. 토양함수율 10%이상 지속일수는 플라스틱 투명용기가 5일, 흑색비닐포트가 3-4일, 플러그 트레이 2일, I-포트가 1일 순이었다. 생존율은 흑색비닐포트가 80%, 플라스틱투명용기가 70%, I-포트가 55% 및 플러그 트레이가 15% 순으로 나타났다. 또한 생육량은 플라스틱 투명용기가 가장 왕성하였고, 흑색비닐포트와 플러그 트레이는 비슷하였으며, I-포트가 가장 저조하였다. 런너 발생은 흑색비닐포트가 주당 3.3개로 가장 많았으며, 플라스틱투명용기가 2.9개, 플러그 트레이가 1.6개 및 I-포트가 1.2개 순으로 나타났다. 총 생산비용은 흑색비닐포트가 44,405,300원/10a로 I-포트의 51,064,700원/10a보다 6,659,400원/10a이 더 절감되었으며, 총 생산주수도 흑색비닐포트가 102,718주/10a로 I-포트의 72,452.9주/10a보다 30,265.1주/10a 더 생산되었다. 또한 주당 생산비용은 흑색비닐포트가 432.3원으로 I-포트의 704.8원에 비해 272.5원의 감소하였다. 따라서 생물반응기를 통해 대량증식된 사계성 딸기 조직배양묘의 순화용기는 흑색비닐포트가 적당하였다.

This study is to investigate the effect of split application and adapted fertilization application cultivation in stable medicinal herbs production of Acorus graminens S. And it accomplished one's purpose to GAP guide manual established standard method of cultivation technology, contribute to the enlargement of farm's income. Method of fertilization application were conducted under five condition compose to standard application(N-P-K-Compost: fermented mixed oil cake fertilizer applied at $4-2-6-300kg.10a^{-1}$, twofold application(N-P-K-Compost applied at $8-4-12-600kg.10a^{-1}$) cultivation. Compost (fermented mixed oil cake fertilizer) and fused phosphate applied at 100% of basal fertilizer in April 14. The split application level of standard application and twofold application(N-K) applied at 100%, 50%, 40% of basal fertilizer in April 14, 50% and 40% of top dressing were three times application (N-K) in June 1, July 15, August 15, 25% and 20% respectively. Transplanting with Naju varieties in May 12 by growing pot seedling for 40 days in 2015. Planting density were spaced 30 cm apart in rows 30 cm apart with black vinyl mulching on open cultivation. Plot design randomized block 3 repetition. Therefore, growth characteristics by 50% and 40% of top dressing were three times application (N-K) compared to standard application and twofold application (N-K) applied at 100% basal fertilizer, aerial part as a result were so many such amount of growth as number of leaf per plant, etc., Length of diameter and main root of subterranean part growth increment rising highest. Dried roots yields treated standard fertilizer 100% application($250kg.10a^{-1}$) compared to 100% from twofold application (N-K) applied at 50% basal fertilizer, 50% and 40% of top dressing were three times application increased by 16%, 20%. respectively.
