Abstract

This study was conducted to increase the income of cactus farm by selecting cheaper and better media than the peat moss using for Gymnocalycium mihanovichii 'Huhong'. We cultivated Gymnocalycium mihanovichii 'Huhong' on 10 kinds of media (peat moss, culture medium, coco peat, sphagnum moss, hydro ton, hydro cray, hydro bal, hugato, vermiculite, perlite) and analyzed media's physiochemical factors and growth, betacyanin. The results were as follows: In case of media's physical condition planting Gymnocalycium mihanovichii 'Huhong' after 90 days, an approximate value with peat moss is culture medium and coco peat. Also, coco peat has no change in chemical media. The rate of growth and development is high in Coco peat while overall culture medium and coco peat was seen lower growth. The level of betacyanin in subirrigation is higher than overhead irrigation. Meanwhile, hugato among 10 kinds of media has high value in both of overhead irrigation and bottom watering. Thus, culture medium and coco peat is proper for alternation of peat moss due to similar value with peat moss. And coco peat is favorable to media, growth condition, pigment.

본 연구는 수출용 접목선인장 '후홍'의 기존에 사용되고 있는 배지인 피트모스 보다 가격이 낮으며 생육이 양호한 배지를 선발하여 선인장 농가의 비용절감을 이끌어내어 소득증대를 높이고자 수행되었다. 접목선인장 '후홍'을 10종류 배지(피트모스, 배양토 BM6, 코코피트, 수태, 하이드로톤, 하이드로크레이, 하이드로볼, 휴가토, 버미큘라이트, 펄라이트)에 재배하여 배지의 이화학적 성분과 생육, 베타시아닌을 조사분석한 결과 다음과 같았다. 수출용 접목 선인장 '후홍'의 식재 90일 후 배지의 물리성에서 대조구인 피트모스와 가장 유사한 값을 보인 배지는 배양토(BM6)과 코코피트였으며 배지의 화학성에서는 코코피트가 90일 후에도 급격한 변화가 없어 큰 변화를 보인 다른 배지에 비해 안정된 모습을 보였다. 생육은 코코피트에서 높은 생육을 보였으며 배양토(BM6)와 수태는 전체적으로 다른 배지에 비해 낮은 생육상태를 보였다. 베타시아닌 색소는 두상관수와 저면과순처리 중 저면관수에서 조금 더 높은 값을 보였다. 10개의 배지에서는 휴가토가 두상관수, 저면관수 모두 높은 값을 보였다. 이와 같이 대조구인 피트모스와 유사한 값을 보이며 배지, 생육, 색소에서 양호한 상태를 보인 코코피트가 적합할 것으로 판단되었다.
