Abstract

This study was carried out to investigate the effect of several subtrates on the growth of cucumber and tomato seedlings. Cucumber and tomato seeds were sown in plug trays that were filled with eight differenct kinds of substrates. One of them was filled with recycled rockwool by 100%. The other six were mixed with used rockwool media:several ratios of recycled rockwool+peatmoss (1:1, 1:2, 1:3, v/v) and recycled rockwool+chestnut wood ships (1:1, 1:2, 1:3, v/v), and the last was 100% chestnut wood chips. The growth of cucumber and tomato seedlingsin 72 plug tray was better in recycled rockwool+peatmoss (1:2, v/v) substrates that the others tested. CEC 9cation exchange capacity) and EC was a little higher in mixed substrates that blended with organic media. But 100% chestnut wood chips and mixed ones with recycled rockwool inhibited severely the growth of seedlings, especially in tomatos. Therefore, it is suggested that the recycled rockwool be capable of utilization to raise seedlings of cucumber and tomato.

오이의 생육과 과실의 품질에 미치는 재활용 폐암면, 피트모스, 밤나무 파쇄입자 및 이들의 혼합배지의 효과를 실험한 바 다음과 같은 결과를 얻었다. 플러그 트레이(72공)를 이용한 오이와 토마토 육묘용 배지 시험에서 재활용 폐암면과 밤나무 파쇄입자 단용배지 그리고 각각을 피트모스와 혼합한 6가지 처리(1:1, 1:2, 1:3, v/v), 총 8종류의 배지를 이용하였다. 그 결과 재활용 폐암면과 피트모스를 1:2(v/v)로 혼합한 구에서 오이와 토마토 모두에서 묘의 생육이 가장 좋았다. 공시한 배지의 화학적 특성을 분석한 결과 유기성 배지를 혼합한 구에서 양이온치환용량과 EC 등이 다소 높았다. 밤나무 파쇄입자 단용 및 혼합처리구에서는 오이와 토마토 묘의 생장이 심하게 억제되었는데, 특히 토마토묘의 억제효과가 컸다. 이상의 결과로 미루어 재활용 폐암면이 오이와 토마토의 육묘용 배지로 이용가능성이 매우 크다는 것을 알 수 있었다.
