Abstract

Strawberry ‘Akihime’ was cultured in raised hydroponic beds which were composed of three kinds of mixed media : 1) peatmoss＋perlite＋granular rockwool (PPG, 1:1:1, v/v); 2) peatmoss＋perlite＋expanded rice hull (PPE, 1:1:1, v/v) and 3) peatmoss＋perlite＋synthetic fibers (PPS, 1:1:1, v/v). The plant growth, fruit yield and medium expenses were investigated. The changes of pH and EC in the draining solution of all media were within the acceptable range for plant growth. The plant height and leaf size were not different among the media. Marketable yield per plant was 617g in the PPG and 601g in the PPE, which were higher than that in the PPS. The cost in the PPE and the PPS were 263 and 250 won per plant, respectively, and these were equivalent to 78% and 74% of the PPG.

딸기 고설식 재배에서 피트모스와 펄라이트의 혼합배지를 기본으로 하고, 입상암면 그리고 산업 부산물로 발생하는 팽연왕겨, 합성섬유 등의 저가 재료를 첨가하여 딸기 생육, 수량 및 배지비용에 미치는 영향에 대하여 검토하였다. 피트모스와 펄라이트에 입상암면, 팽연왕겨 혹은 합성섬유를 혼합한 3종류 배지 모두 재배기간중 배액의 pH 와 전기전도도는 안정적 범위였다. 딸기의 초장, 잎크기 등은 배지종류에 따라 크게 다르지 않았다. 주당 상품수량은 입상암면 혼합배지구에서 601g, 팽연왕겨 혼합배지구에서 617g으로, 합성섬유 혼합배지구의 571g 보다 많았다. 배지비용은 피트모스＋펄라이트＋팽연왕겨 혼합배지의 경우 주당 263원, 피트모스＋펄라이트＋합성섬유 혼합배지의 경우 주당 250원으로, 입상암면 혼합배지의 각각 78%, 74% 수준이었다.
