Abstract

In this study, nutrient solution for Liliaceae (Chinese chive) leafy vegetable was developed. The various strength (1/2, 1 and 3/2) of nutrient solution recommended by National Horticultural Research Institute (NSH) was applied to the crops in deep flow technique (DFT) system for 42 days. The growth of Chinese chive were highest in the treatment of 1/2 strength. The proper constitution of nutrient solution developed for liliaceae crops (NSL) was N 12, P 2.5, K 7, Ca 4 and Mg 2 met. The crops were grown two times in March and September to examine the appropriateness of the NSC. As a result, the relative growth rate and the amount of chlorophyll (SPAD value)of Chinese chive treated with NSL were increased 1.11 times. The most important nutrient factor of ascorbic acid were also increased 1.16 times.

본 연구에서는 양수분 흡수율과 양이온 비율에 근거하여 백합과(부추)에 적합한 전용배양액을 개발하였다. 원예연구소 배양액액(NSH)을 1/2배액, 1배액, 3/2배액의 농도로 42일간 담액 수경재배를 한 결과 1/2배액에서 세가지 작물의 생육이 가장 좋았다. 양수분 흡수율에 근거하여 개발된 백합과 전용배양액(NSL)의 조성은 N 12, P 2.5, K 7, Ca 4 and Mg 2 me/L이다. NSL로 처리한 부추 작물의 상대생장율(RGR)은 1.11배 증가하였으며 엽록소 함량(SPAD value)은 1.16배 증가하였다. 그리고 부추의 가장 중요한 영양성분중 하나인 항산화성분-Ascorbic acid의 함량이 1.16배 증가하였다.
