Abstract

This study was conducted to compare the physicochemical properties of newly developed artificial medium and conventional plug medium and to investigate the proper irrigation interval to produce the high quality tomato seedlings. The five existing artificial media (organic medium coir, mixed medium Tosilee and Q plug, and inorganic medium LC and rockwool) and four newly developed artificial medium (mixed medium TP-S1 and inorganic medium PU 14-S1, PU-7B, and PU 15-S1) were used to grow tomato ‘Yegwang’ with irrigation interval of one-day (14 times), two-day (7 times), and three-day (5 times) for 14 days. The pH was the significantly highest in the PU 15-S1. All growing medium measured were in the range of pH 5.17-6.90. EC was the highest in the Q plug. The initial germination rate was the highest in the PU 15-S1. The final germination rate and mean daily germination were not significantly different in all growing medium except for the PU 14-S1. Growth of tomato seedlings at 15 days after sowing was the greatest in the Q plug. At 29 days after sowing, seedlings were also the greatest in the Q plug, followed by rockwool and PU-7B. Also, growth was better in the one-day interval treatment. As a result, we confirmed the applicability of the artificial medium to tomato plug seedlings in this experiment, and seedlings were the greatest in the Q plug. Therefor, it is considered that adding nutrients to the artificial medium of the newly developed medium PU-7B, and applying the irrigation one-day interval can produces high quality tomato seedlings similar to using Q plug.

본 연구는 우량묘 생산을 위해 신개발된 인공배지와 육묘용 배지의 이화학적 특성을 비교하고 적정 관수 간 격을 구명하기 위해 수행되었다. 5종의 기존 인공배지 (유기배지인 coir, 혼합배지인 Tosilee와 Q plug, 그리고 무기배지인 LC와 rockwool)와 4종의 신개발 배지(혼합 배지인 TP-S1, 그리고 무기배지인 PU 14-S1, PU-7B, PU 15-S1)를 이용하여 토마토(Solanum lycopersicum L.) ‘예광’을 육묘하였으며, 14일간 1일(14회), 2일(7회) 그리고 3일(5회) 간격으로 관수 처리하였다. pH는 PU 15-S1 배지에서 유의성 있게 가장 높았으며, 모든 배지 에서 pH 5.17-6.90의 범위였다. EC는 Q plug 배지에서 가장 높게 나타났다. 초기발아율은 PU 15-S1 배지에서 가장 우수하였다. 최종발아율과 평균발아수는 PU 14-S1 배지를 제외하고는 모든 배지에서 유의적인 차이가 없었 다. 파종 후 15일째 토마토 묘의 생육은 Q plug 배지에 서 우수하였다. 파종 후 29일 째 묘의 생육 또한 Q plug 배지에서 유의적으로 우수하게 나타났고, 다음으로 rockwool과 PU-7B 배지에서 우수하였다. 또한 생육은 1 일 간격 처리에서 가장 우수한 경향을 보였다. 결과적으 로 본 실험에서 토마토 육묘 시 인공배지의 적용가능성 을 확인하였으며, 묘의 생육은 Q plug 배지에서 가장 우 수하였다. 신개발된 PU-7B 인공배지에 양분을 첨가하고 1일 간격으로 관수한다면 Q plug 배지의 결과와 같이 우 수한 토마토 묘를 생산할 수 있을 것으로 판단된다.
