Abstract

To determine the effects of circulation frequency of nutrient solution, three frequencies of 10min. on/10min. off; 10min. on/110min. off; and 10min. on/1,430min. off. treatments were applied to leafy vegetable production using deep flow technique (DFT) systems and their growth and phytonutrient content were investigated. In the 10min. on/I,430min. off treatment, dissolved oxygen concentration (DOC) 17 days after treatment decreased to 2.8mg. $L^{-1}$, known to be a low DOC that causes hypoxia, and thereafter decreased to 1.5mg. $L^{-1}$ 20 days after treatment. Fresh weight of 7 leafy vegetables in the 10min. on/1,430min. off treatment was lower by 0${\sim}$24% than those in the 10min. on/110min. off treatment, and those in the 10min. on/10min. off was higher by -2${\sim}$34% than those in the 10min. on/110min. off treatment as control. As the more frequent circulation was applied, the higher phosphorous content and the lower carbon to nitrogen ratio (C/N ratio) and total ascorbic acid contents were resulted. Results indicate that the circulation frequency of 110min, on/110min. off could be recommended for the production of the tested leafy vegetables in DFT systems.

주요 엽채류 7종의 주년 안정생산을 위한 담액수경 재배 시 양액의 순환주기가 양액의 용존산소 농도, 엽채류의 생육, 그리고 식물영양소의 함량에 미치는 효과를 검토한 결과, 양액을 1일 10분 순환 처리구는 정식 13일 후 용존산소 농도가 급격하게 떨어지고 17일 후에는 2.8mg $L^{-1}$, 20일 후에는 최저 1.5mg $L^{-1}$까지 낮아졌다. 처리 20일 후 7가지 엽채류의 생체중은 1일 10분 처리구에서는 대조구인 10분 순환/110분 정지 처리구에 비해 $0{\sim}24%$ 범위에서 낮아졌으며, 10분 순환/10분 정지 처리구에서는 $-2{\sim}34%$ 증가하였다. 양액의 순환주기가 짧을수록 식물체 엽내 P의 함량이 증가하였으며, 식물체의 C/N율과 비타민 C 함량은 감소하였다. 이상의 결과, 담액수경 엽채류의 안정적인 생육과 식물영영소의 흡수를 위해서 2시간에 10분 정도의 양액 순환 처리가 효율적이었다.
