Abstract

This experiment was conducted to find out the possibility of use of reused rockwool and comparison of growth, productivity and quality of tomatoes according to the use of rockwool and coir medium. The experiment was conducted in an automatic controlled greenhouse at Andong National University, College of Life Science, located in Andong, Gyeongsangbuk-do.. As a result of the experiment, there was no difference in the number of leaves, plant height, and leaf area between treatments, and the crown diameter was slightly higher in rockwool medium, also there was no difference between reused rockwool and coir medium. Fruit productivity showed different responses depending on the cultivation environment, but there was no significant difference between rockwool, reused rockwool and coir medium. In addition, the quality of fruit was observed to be different according to the concentration of EC in the medium. Therefore, in tomato hydroponic cultivation, there was no difference in the type of medium in growth, productivity, fruit quality and the environmental and water management had a great effect, and it is expected that the reuse of rockwool will have a positive effect on the economic point of view.

본 실험은 암면과 코이어 배지의 이용에 따른 토마토의 생육, 생산성 및 품질 비교 및 재사용암면 이용가능성을 알아보기 위해 경북 안동시에 위치한 안동대학교 생명과학대학 자동 제어온실에서 진행되었다. 실험결과 토마토의 엽수, 초장, 엽면적은 처리간 차이가 없었으며 줄기직경은 암면배지에서 약간 높은 경향을 보였지만 재사용암면 및 코이어배지간의 차이는 없었다. 과실생산성은 기상 조건에 따라 상이한 반응을 보였지만, 암면, 재사용암면 및 코이어배지간의 큰 차이를 보이지 않았다. 또한 과실의 품질은 배지 내 EC의 농도에 따른 차이를 보였다. 따라서, 수경재배에서 토마토의 생육 및 과실품질은 배지의 종류에 대한 차이가 없었으며 환경 및 급액관리에 따른 영향이 컸다. 본 실험을 통해 토마토 수경재배에서 생육단계별 적정 수분관리기술이 적용된다면 암면의 재사용에 따른 경제성 향상에 기여될 수 있을것으로 판단된다.
