Abstract

The study was conducted in a greenhouse to examine the possibility of floral foam media use in hydroponic of Rosa hybrida. pH change in medium of rockwool, coir and floral foam at early time was stabilized from 5.6 to 6.2. However after 2 years, hydroponic culture system became acidic from 4.7 to 5.1. EC was higher in coir media than in rockwool media and floral foam media immediately after nutrient solution irrigation. However rockwool was 2.3 $dS{\cdot}m^{-1}$, coir was 2.5 $dS{\cdot}m^{-1}$ and floral foam media was 2.7 $dS{\cdot}m^{-1}$ at the hydroponic system after 2 years. Fluctuation of ion accumulation was detected in each media. Only T-N was increased at rockwool media. All components of fertilizer were generally increased in floral foam medium. In coir medium, T-N and CaO was increased while $K_2O$, $P_2O_5$ and $Na_2O$ were decreased. Rooting rate by different media in Rosa hybrida cutting was effective in orders of floral foam, rockwool and coir. In case of growth, length of cut flower was increased in rockwool media culture. But significant differences were not found in flower height, flower diameter and cut flower harvest yield. Overall, compared with media of rockwool and coir, floral foam was equivalent. Therefore, in hydroponic culture of Rosa hybrida, the obtained results seem that rockwool and coir can be replaced to floral foam.

장미 재배시 플로랄폼 배지의 사용 가능성을 알아보기 위해 시험한 결과 배지별 pH 변화의 경우 초기 재배시에는 5.6 ~ 6.2의 범위로 안정적이었으나, 2년 재배 후에는 배지 종류에 관계없이 4.7~5.1의 범위로 산성화 되는 경향이었다. EC의 경우 관수직후에는 암면 배지나 플로랄폼 배지에 비해 코이어 배지에서 높았으나, 2년 재배 후에는 암면 배지에서는 2.3 $dS{\cdot}m^{-1}$이었으며 코이어 배지는 2.5 $dS{\cdot}m^{-1}$ 및 플로랄폼 배지는 2.7 $dS{\cdot}m^{-1}$로 나타났다. 배지별 이온 축척량의 경우 암면 배지는 질소의 함량만 증가 하였을 뿐 기타성분은 감소하는 추세였고 플로랄폼 배지의 경우에는 대부분의 비료성분이 증가되었다. 그러나 코이어 배지에서는 질소, 칼슘이 증가되었고 인산, 칼륨 및 나트륨 성분은 감소되었다. 장미 삽목 후 배지별 발근율은 플로랄폼 >암면 >코이어 배지 순이었다. 장미 생육의 경우, 절화장은 암면 배지에서 컸으나 화고, 화폭 및 절화수량은 배지별 차이가 없었다. 전체적으로 볼 때 장미 양액재배 시 암면배지와 코이어 배지는 플로랄폼 배지 사용과 유사한 생육을 보였다. 이는 기존 사용 배지인 암면배지와 코이어배지를 플로랄폼 배지로 대체할 수 있을 것이다.
