Abstract

Production cost as well as environmental contamination can be reduced by reuse of drained nutrient solution in hydroponic. This research was conducted to obtain the information in changes in inorganic elements concentration of supplied and drained nutrient solution as well as of plant leaves. To achieve the objective, the samples of supplied and drained solution and cherry tomato leaf tissues were periodically collected and analyzed during the hydroponic cultivation. The electrical conductivity (EC) of supplied and drained nutrient solution in early growth stage of cherry tomato were measured as around 2.0 dS·m-1, but those values move up with the passage of time reaching to 2.0 dS·m-1 at flowering stage of 9th fruiting node. The pHs of drained solution in early growth stage were 6.4 to 6.7, however those showed a tendency to get lowered to 5.9 to 6.1 as time passed during the crop cultivation. The concentration differences of NO3-N, P, K, Ca, and Mg between supplied and drained solution were not distinctive until flowering stages of 4th fruiting nodes, while those in drained solution moved up after the stage. The tissue N contents of leaves decrease gradually and those of K and Ca increased as crops grew. However, Tissue P and Mg contents were maintained similarly from transplant to end-crop. The above results would be used in correction of drained nutrient solution when element compositions are varied compared to supplied solution in hydroponic cultivation of tomatoes.

수경재배 시스템에 있어서 배액의 재활용은 생산비 절 감 및 환경오염 방지를 위하여 중요하다. 방울토마토를 반촉성 수경재배 하면서 생육 단계별 공급액, 배액 및 잎의 무기성분 분석을 통하여 순환식 수경재배 시스템 개발을 위한 기초자료를 확보하고자 본 연구를 수행하였 다. 연구목적을 달성하기 위해 주기적으로 공급액, 배액 및 식물체 잎을 채취한 후 무기물 함량을 분석하였다. 생육 초기에는 배액의 EC가 공급액과 비슷한 약 2.0dS·m-1였지만, 생육 후기로 갈수록 높아져 9화방 착과 기에는 4.5dS·m-1였다. 영양생장이 왕성한 생육 초기의 pH는 6.4~6.7 범위였으나 생식생장이 강해진 생육 후기 에는 5.9~6.1로 낮아지는 경향이었다. 생육 초기에는 공 급액과 배액의 NO3-N, P, K, Ca 및 Mg 농도가 비슷하 였지만 생육 후기로 갈수록 공급액보다 배액의 농도가 높아지는 경향이었다. 생육 초기에 잎의 T-N 함량이 높 았지만 후기로 갈수록 낮아지는 경향이었다. K와 Ca 함 량은 생육 초기에는 낮았으나 후기로 갈수록 높았으며, P와 Mg 함량은 생육초기부터 후기까지 유사한 수준으로 분석되었다. 이상의 결과는 토마토 수경재배를 배액 재 활용에 있어 무기원소 농도 변화를 교정하기 위한 기초 자료로 활용될 수 있을 것이다.
