Abstract

This experiment was conducted to investigate the effect of water soluble fertilizer(WSF) and slow release fertilizer(SRF) on the growth of carnation(Dianthus caryophyllus 'Invitation') cultured in C-channel mat irrigation system. Plants grown in $0.8{\~}1.0\;g{\cdot}L^{-1}$ of WSF showed the highest quality, especially on fresh and dry weight of aerial part, leaf number, total leaf area, plant height, and branch number. All plants showed increase of growth rate around 60 days after treatment, although there was a different increase rate. Total leaf area decreased its increase rate after 90 days after treatment. Carnations supplied by WSF showed better growth and quality than SRF, and the optimum concentration range of WSF for pot-carnation was $0.8{\~}1.0\;g{\cdot}L^{-1}$ in C-channel mat irrigation system.

고품질 분화생산을 위한 저면관수 시스템인 C-형강 매트재배 시 수용성 비료와 완효성 비료의 농도에 따른 카네이션의 생육을 연구하기 위하여 본 실험을 수행하였다. 수용성 비료를 $0.8{\~}1.0\;g{\cdot}L^{-1}$ 처리한 T08 처리구에서 생체중, 건물중, 엽수, 엽면적, 초장, 분지수의 생육량에서 가장 양호하였다. 생체중, 건물중, 및 초장의 증가에 있어서 증가량에서의 차이는 있었지만 생육 60일을 전후로 비료의 종류에 관계없이 증가량이 늘어났다. 특히 총 엽면적은 경우 생육 90일을 전후로 증가가 완만해지는 경향을 나타내었다. 이 결과를 통하여 C-형강 매트 재배시스템에서 분화용 카네이션을 재배할 경우 수용성 비료를 공급하는 것이 완효성 비료를 공급하는 것보다 효과적인 것으로 나타났고, 수용성 비료의 농도는 $0.8{\~}1.0\;g{\cdot}L^{-1}$이 카네이션의 재배에 적정한 농도로 판명 되었다.
