Abstract

Recycling of drained nutrient solution in hydroponic cultivation of horticultural crops is important in the conservation of the water resources, reduction of production costs and prevention of environmental contamination. Objective of this research was to obtain the fundamental data for the development of a recirculation system of hydroponic solution in semi-forcing cultivation of 'Bonus' tomato. To achieve the objective, tomato plants were cultivated for 110 days and the contents of inorganic elements in plant, supplied and drained nutrient solution were analyzed when crop growth were in the flowering stage of 2nd to 8th fruiting nodes. The T-N content of the plants based on above-ground tissue were 4.1% at the flowering stage of 2nd fruiting nodes (just after transplanting), and gradually get lowered to 3.9% at the flowering stage of 8th fruiting nodes. The tissue P contents were also high in very early stage of growth and development and were maintained to similar contents in the flowering stage of 3rd to 7th fruiting nodes, but were lowed in 8th node stages. The tissue Ca, Mg and Na contents in early growth stages were lower than late growth stages and the contents showed tendencies to rise as plants grew. The concentration differences of supplied nutrient solution and drained solution in $NO_3-N$, P, K, Ca, and Mg were not significant until 5 weeks after transplanting, but the concentration of those elements in drained solution rose gradually and maintained higher than those in supplied solution. The concentrations of B, Fe, and Na in drained solution were slightly higher in the early stages of growth and development and were significantly higher in the mid to late stages of growth than those in supplied solution. The above results would be used as a fundamental data for the correction in the inorganic element concentrations of drained solution for semi-forcing hydroponic cultivation of tomato.

순환식 수경재배 시스템을 이용한 배액의 재활용은 수자원 및 생산비 절감, 환경오염 방지를 위하여 중요하다. 따라서 일반 토마토인 'Bonus'를 110일간 반촉성 수경재배하면서 생육 단계별 식물체, 공급액 및 배액의 무기원소 농도 분석을 통하여 순환식 수경재배 시스템 개발을 위한 기초 자료를 확보하고자 본 연구를 수행하였다. 착과절위에 따른 엽의 T-N 함량은 생육 초기에 약 4.1%로 높았으나 생육 후기로 갈수록 낮아져 8화방 개화기에는 3.9%로 낮아졌다. P 함량은 초기에 높았으며, 3-7화방까지는 비슷하였고, 8화방에서 낮았다. Ca, Mg 및 Na은 생육초기보다 후기로 갈수록 함량이 높아져 8화방 개화기에 가장 높았다. 토마토 생육 기간이 경과할수록 공급 양액과 배액의 $NO_3-N$, P, K, Ca 및 Mg 농도는 정식 5주 후까지의 생육 초기에는 비슷하였으나 생육 후기로 갈수록 공급액보다 배액에서 농도가 높아지는 경향이었다. B, Fe 및 Na의 경우 생육 초기에는 배액의 농도가 약간 높았으며 중기 이후부터 공급액보다 배액의 농도가 높았다. 이상의 결과는 토마토 순환식 반촉성 수경재배 시 배액의 무기원소 농도를 교정하기 위한 기초 자료로 활용될 수 있을 것이다.
