Abstract

This work is for selecting superior media which is similar to Peat Moss that is in general use as media of Gymnocalycium mihanovichii for Export such as 'Hwang wall' but lower price. The result on growth of 7 kinds of media (Peat Moss, BM6 Culture Medium, Coco Peat, Hydro Cray, Hydro Ball, Hugato, Vermiculite) which are applied watering (overhead irrigation, sub irrigation) based on bichemical analysis including chemical, physical analysis are following. The result of bi-chemical analysis shows that Coco Peat was stabilized planting after 90 days and Hydro Ball has high water holding capacity. The experimental result of growth in grafted cactus 'Hwangwall' shows Coco Peat is similar to Peat Moss on organic matter and in case of inorganic media, Hugato, Vermiculite, Hydro Cray made satisfactory results. But, the weight of inorganic media is too light to be tied. Consequently, Coco Peat and sphagnum moss as organic media has lower price and the condition of growth is analogous to Peat Moss. On the other hands, Hydro Ball was chosen as a substitute of Peat Moss in inorganic media.

수출용 접목선인장 '황월'의 기존에 사용되는 배지인 피트모스 보다 가격이 낮으며, 생육이 피트모스와 비슷한 배지를 선발하고자 7가지 종류 배지 (피트모스, 배양토 BM6, 코코피트, 하이드로크레이, 하이드로볼, 휴가토, 버미큘라이트)에 재배하여 배지의 이화학적 성분과 생육변화를 조사하였다. 배지의 이화학적 분석결과로는 코코피트가 식재 90일 후에도 이화학적 성분의 변화가 거의 없어 안정적이었으며, 하이드로볼이 보수력이 높은 것으로 조사되었다. 수출용 접목선인장 '황월'의 생육조사 결과 유기질 배지에서 대조구인 피트모스와 비슷한 생육을 보인 배지는 코코피트 였으며, 무기질 배지에서는 휴가토, 버미큘라이트, 하이드로클레이가 대체적으로 양호한 생육을 보였다. 그러나 무기질 배지는 무게가 가벼워 식물식재 후 이동 시 쓰러지는 단점이 있었다. 피트모스와 비슷한 생육조건과 낮은 가격을 가진 배지로는 유기질 배지인 코코피트와 수태를 감싸지 않고 사용할 수 있는 무기질 배지인 무게가 상대적으로 무겁고 값이 낮으며 국내 생산이 되는 하이드로볼이 수출용 선인장 재배 배지로 적합할 것으로 판단되었다.
