Abstract

To overcome a decrease of Korean ginseng production caused by successive cropping, we have tried to develop a nutrient culture system for Korean ginseng production. For determining the optimal substrate, mixture of sand and TKS-2 (S＋T), peatmoss (P), reused rockwool (RR), and granular rockwool (GR) were investigated. The overall physico-chemical properties of RR fell into the reported optimal range for the ginseng cultivation. However, bulk density of S＋T was a little higher than that of soil in Korean ginseng fields. The top fresh weight of the ginseng was high in RR and S＋T substrates. The root fresh and dry weights in the RR were remarkably greater than that in the conventional soil (CS) of Korean ginseng fields. In terms of ginseng quality, the vitamin C content of ginseng root in nutrient culture was higher than that in CS. However, the contents of crude saponin and total ginsenosides in ginseng between in the nutrient culture and in the soil culture did not show any significant differences.

한국의 인삼재배시 연작장해로 인한 생산량 감소가 문제가 되고 있다 이를 극복하기 위하여 본 연구에서는 한국인삼 재배를 위하여 양액재배 시스템을 적용하였다. 최적의 양액재배용 배지를 선발하기 위하여 모래, TSK-2 (S＋T), 피트모스 (P), 재활용 암면 (RR)과 입상 암면 (GR)등의 다양한 배지를 단독 및 혼합처리구로 사용하였다. RR배지의 경우 전반적인 물리화학적 특성은 기존에 보고된 인삼배지의 토양특성과 유사하였다. S＋T배지는 가밀도가 인삼용 토양보다 높았다 인삼의 지상부 생체중은 RR배지와 S＋T배지에서 높았다. 인삼 뿌리의 생체중 및 건물중은 RR배지에서 가장 높았다. 인삼의 뿌리의 품질적 측면에서 vitamin C함량은 양액재배로 생육시킨 인삼이 토양에서 생육한 인삼보다 높았으나, crude saponin과 ginsenosides 함량에서는 차이를 나타내지 않았다.
