Abstract
This study was conducted to develop a nutrient uptake model in cucumnber (Cucumis sativus L. cv. Eunsung Backdadagi) plants for prediction of the amount of nutrients in drainage solution in a closed perlite culture system. Electrical conductivity (EC) of the nutrient solution was adjusted to 1.5, 1.8, 2.1, 2.4, and 2.7 dS.
순환식 펄라이트재배에서 배액 재사용을 위한 양분흡수 모델링을 작성하고자 양액 농도(1.5, 1.8, 2.1, 2.4, 2.7 dS./m-1)를 달리하여 수행하였다. 생육 중기까지 전기전도도(EC) 수준에 따른 양액흡수량은 차이가 없었지만 중기 이후 EC가 높을수록 흡수량이 감소되는 경향을 보였다. N
