Composition of Nutrient Solution for Endive(Cichorium endivia L.) Hydroponics

엔디브 양액재배에 적합한 배양액 조성

This experiment was conducted to composition of nutrient solution for tore of endive hydroponics, and was compared the nutrient solution developed in the Seoul City University(SCUE) with the conventional solution of Proefstation voor Tuinbouw ender Glas. Proper compositions of nutrient solution for endive hydroponics were NO$_3$-N 15.0, NH$_4$-N 1.0, PO$_4$-P 3.0. K 10.0, Ca 5.0 and Mg 3.5 me.$\ell$$^{-1}$ , respectively SCUE and PTG standard nutrient solution showed slightly better yields among nutrient solutions. The SCUE nutrient solution and the PTG nutrient solution had no difference on growth and yield of endive Plants.

본 실험은 엔디브 양액재배에 적합한 배양액을 조성하고. 새로 조성한 배양액(SCUE)의 효과를 검토하고자 수행하였다. 엔디브 재배에 적합한 배양액을 양수분 흡수율에 의해 조성한 결과 NO$_3$-N 15.0, NH$_4$-N 1.0 PO$_4$-P 3.0. K 10.0, Ca 5.0, Mg 3.5 me.$\ell$$^{-1}$가 적당하였다. 새로 조성한 서울시립대 엔디브액 (SCUE)과 유럽의 엔디브액간의 재배실험 결과, 배양액간의 생육 및 수량은 차이가 없었지만, pH와 EC의 변화폭은 새로 조성한 양액에서 적었다.
