Abstract

Organic and inorganic substrates commonly used in Korea include peat moss, coir, bark, rice hull, saw dust, perlite, vermiculite, rockwool granulate, clay ball, and so on. The objective of this study was to get analytical results about the physical and chemical properties of these substrates by European standard methods. Organic substrates showed different properties depending on the type, origin and manufacturing processes. Inorganic substrates showed different properties depending on the type and particle size. Further study on physical and chemical properties for more raw materials and commercially available growing media analyzed by European standard method and comparison of the results with those by Korean standard method is needed.

국내 원예산업의 발달에 따라 다양한 종류의 배지 이용이 급속히 증가되고 있다. 현재 국내에서 사용중인 유기성 배지에는 피트모스, 코이어, 바크, 왕겨, 톱밥 등이 있으며, 무기성 배지로는 펄라이트, 버미큘라이트, 암면, 클레이볼 등이 있다. 본 연구는 유럽표준배지분석방법에 따라 원예용 배지를 분석하여 이들의 물리화학적 특성을 구명하고자 수행되었다. 국내에서 사용 중인 몇 가지 배지를 분석한 결과, 유기성 배지인 피트모스, 코이어, 바크, 톱밥, 왕겨는 종류, 원산지, 가공방법 등에 따라, 무기성 배지인 펄라이트, 버미플라이트, 입상암면, 클레이볼은 종류, 입자크기 등에 따라 이들의 물리화학적 특성의 차이를 보였다. 앞으로 유럽 표준분석방법 뿐만 아니라 국내 표준배지분석법에 따라 더 많은 배지재료와 혼합배지 및 상토를 분석함으로써 국내 배지분석법의 정립, 이상적인 배지의 기준 제시, 두 분석방법간의 환산인자확보 등의 연구가 요구된다.
