Abstract

This experiment was conducted to find out the possibility of which mixed mediums combined waste rock wool slab with other materials may be good for substrate of cut rose Vital at the hydroponic culture for three years. Porosities of the media were all over 90% except that using particles of reused rock wool (RR). Gaesous phase rate was highest in mixed reused rock wool slab with perlite (RR+P) by 21.7%. All media showed mild acidity about pH 6.5, but it has showed mild alkalic pH 7.08 in new rock wool slab (NR). Almost all media had safety condition in terms of salinity less than 0.5 dSm EC, but level of Caand SO in the media of high temperature season was concentrated higher in RR+pine wood chips (PC) and RR+chestnut wood chips than other mediums. Cut flower yield was the most plentiful in RR+PC medium as 617.8 stems per 10 plants and marketable flower rate was maintained in all media above 90% for three years.

절화 재배 배지로서 폐암면의 재활용 가능성을 검토하기 위하여 폐암면과 목재 파쇄 입자 등과 혼합한 배지를 이용하여 절화용 장미 Vital을 3년간 양액 재배하였다. 배지의 공극률은 폐암면 100% 배지를 제외하고는 90% 이상이었고, 기상률은 폐암면+펄라이트 혼합 배지에서 21.7%로 가장 높았다. 배지의 pH는 새 암면은 7.08로 약 알칼리성이었고, 나머지 배지는 6.5 정도의 약산성이었으며, 배지 내 염류 농도는 대부분이 EC 0.5dSm 이하의 안정된 조건을 갖추고 있었다. 재배 기간 중 특히 여름철 고온기 배지내 염류 농도는 폐암면+소나무, 폐암면+밤나무 혼합 배지에서 Ca와 SO가 다른 배지에 비해 많이 집적되었다. 3년간의 10주당 절화 수량은 폐암면+소나무 혼합 배지에서 617.8본으로 가장 많았고, 상품률은 모든 배지에서 90% 이상을 유지하였다.
