Abstract

The experiment has investigated the effects of growth, yield, and fruit quality of strawberries by three different kinds of substrates. Commonly used media cocopeat, cocopeat mixed with rice hulls and compound nursery media were used to select a proper medium by comparing growth status, yield and fruit quality. Number of leaves was most in cocopeat substrate, and leaf length and leaf width were highest in compound nursery media. Fruit weight was heaviest in compound nursery media, but there were no significant statistical differences in fruit length, fruit width and soluble solids of fruit. Number of fruits per plant was much in compound nursery media and cocopeat than cocopeat mixed with rice hulls. The most yield per plant was in compound nursery media and the least it was in cocopeat mixed with rice hulls. The results of this experiment will be utilized in the new substrate application for strawberry hydroponics.

본 실험은 딸기의 고설수경재배에 이용 가능한 적정한 배지를 조사하기 위하여 수행하였다. 코코피트 배지에서 엽수가 가장 많았으며, 원예용 상토배지에서 엽장과 엽폭이 가장 우수했다. 과중은 통계적인 유의성은 없었지만 원예용 상토배지에서 25.8g으로 가장 높게 나타났고 과장, 과경, 당도 등도 처리 간에 유의한 차이는 없었지만 원예용 상토배지에서 가장 좋은 결과를 나타내었다. 주당 수확과수는 원예용 상토와 코코피트 배지 모두 왕겨 혼합배지보다 유의하게 높은 수치를 나타내었다. 주당 수량은 원예용 상토배지가 545.9g으로 가장 많았으며, 그 다음으로 코코피트 배지에서 높았으며 왕겨 혼합배지에서 가장 낮았다. 본 연구에서는 딸기의 수경재배에 적합한 고형배지로서 생산자가 구입과 작업이 편리하고 물리성이 좋은 원예용 상토의 우수성을 입증하여, 딸기 재배농가에게 유용한 정보로 활용될 수 있을 것으로 기대되며 타 작물의 고형배지 재배에서도 유용하게 이용될 것으로 생각된다.
