Abstract

This research was conducted to investigate the influence of post-planting fertilizer concentrations on the growth of seedlings and changes of nutrient concentrations of media in tomato seedling production through sub-irrigation. Two root media such as peat moss (grade of 0 to 6 mm, PM06) plus perlite (grade of 1 to 2 mm (PE2)(7:3, v/v) and peat moss (grade of 5 to 15 mm, PM515) plus PE2 (7:3, v/v) were formulated and filled into 72-cell plug trays. After seeds of 'Dotaerang Dia' tomato were sown and germinated at $28^{\circ}C$, the trays were moved to greenhouse and seedlings were raised 35 days. When the cotyledons were emerged, post-planting fertilizers of 13-2-13, 15-0-15 and 20-9-20 ($N-P_2O_5-K_2O$) were applied in a sequence. The fertilizer concentrations based on N in each plug stage were differed with $25mg{\cdot}L^{-1}$ in three treatments. The fertilizer solutions were supplied when the weight of plug trays decreased to 40 to 50% compared to container capacity. The root media were collected in 1, 2, 4, and 5 weeks after sowing and were divided into top, middle, and bottom parts, then were analysed for pH, EC and macro-nutrient concentrations. The seedling growth was investigated 5 weeks after sowing. The pH and EC in PM06+PE2 was higher than those of PM515+PE2. The bottom and mid-part had higher pH and lower EC compared to upper part in each medium. The differences of EC between upper and bottom parts were around 2 times in each medium. The $NH_4-N$ and K concentrations in program 3 of PM06+PE2 showed the highest concentrations among all treatments. The $NO_3-N$ concentrations in PM06+PE2 increased gradually and this rising tendency become severe as post-planting fertilizer concentrations were elevated. The seedling growth in terms of fresh and dry weights was the highest in the treatment of program 2 in PM06+PE2 among all treatments tested. Above results indicate that the gradual increases of fertilizer concentrations from 25 to $125mg{\cdot}L^{-1}$ in plug stages 2, 3, and 4 plug stages are desirable for

토마토를 저면관비 방법으로 육묘할 때 유묘 생장과 상토 무기원소 농도 변화에 적합한 추비의 종류 및 농도를 구명하기 위해 본 실험을 수행하였다. 육묘용 2종류의 동절기 혼합상토 피트모스 0-6mm(PM06)+perlite 1-2mm(PE2)(7:3, v/v)와 피트모스 5-15mm(PM515)+PE2(7:3, v/v)를 72공 플러그 트레이에 각각 충전하고 토마토 '도태랑다이아' 종자를 파종하여 발아시킨 후 생장상에서 35일간 육묘하였다. 자엽형성기에 추비를 시작하였고 13-2-13, 15-0-15, 20-9-20($N-P_2O_5-K_2O$) 복합비료를 순서대로 처리하였다. 추비시 생육 단계별로 $25mg{\cdot}L^{-1}$의 농도차(N 기준)를 둔 3종류의 Program을 두어 시비하였으며, 플러그 트레이의 수분이 포화 기준으로 40-50%로 감소하였을 때 저면관비하였다. 파종 후 1, 2, 4 및 5주째 혼합상토를 상부, 중간, 하부로 3등분하여 포화추출한 후 추출용액의 pH, EC 및 무기이온 농도를 분석하고, 5주 후에 유묘생장을 조사하였다. 육묘 기간 중 상토의 pH는 PM06+PE2가 PM515+PE2 보다 높았으며, 하부와 중간이상부보다 높은 경향이었다. EC는 PM06+PE2가 PM515+PE2보다 높았으며 평균적으로 상부가 하부보다 2배 이상 높았다. $NH_4-N$과 $K^+$ 농도는 2종류 혼합상토의 모든 시비 Program에서 육묘 후 5주까지 높아졌으며, PM06+PE2의 추비 프로그램 3에서 가장 높았다. $NO_3-N$ 농도는 PM06+PE2에서 육묘기간 동안 높아졌고 추비농도가 높을수록 그러한 경향이 뚜렷하였다. 지상부 생체중을 비롯한 유묘의 생장은 PM06+PE2의 추비 Program 2에서 가장 우수하였다. 따라서 2종류 혼합상토를 이용한 공정육묘시 13-2-13, 15-0-15 및 20-9-20을 순서대로, 질소 기준 $25mg{\cdot}L^{-1}$에서 $125mg{\cdot}L^{-1}$까지 육묘기에 따라 점차적으로 높여 추비하는 방법이 적합하다고 판단하였다.
