Abstract

For autumn cutting of Sedum sarmentosum, the influences of bedsoil and cutting date were investigated. Among six kinds of bedsoils mixed upland soil, carbonized rice and sand, the mixture with upland soil and sand (1:1 and 2:1, v/v) showed excellent root and shoot growth. The mixtures with upland soil and carbonized rice were lower rooting than the mixture with upland soil and sand. In field condition, autumn cutting was conducted with $10{\times}5cm$ space using the mixture with upland soil and sand (2:1, v/v) at intervals of 10 days from September 1 to October 10. Both root and shoot growth were significantly decreased by delayed date. In cutting from early to middle September, root and shoot growth, and number of rosette before wintering were desirable for shoot production next spring. The safety date to autumn cutting before wintering was on September 20 in field condition. If autumn cutting is late than September 20, the number of scion has increased 25-30% to secure a full rosette before wintering. The results could provide the beneficial information for cutting propagation of S. sarmentosum under field condition in autumn.

돌나물의 가을 삽목번식을 위한 적정 삽목용토와 삽목시기를 조사하기 위하여, 농가에서 손쉽게 구할 수 있는 밭흙, 강모래와 훈탄을 혼합한 삽목용토의 효과를 조사하였다. 밭흙과 모래를 1:1 또는 2:1(v/v)로 혼합하여 사용하는 것이 활착, 지상부 생육 및 뿌리발달이 양호하여 경제적이었다. 선발된 삽목용토(밭흙:모래=2:1) 를 이용하여 $10{\sim}5cm$ 간격으로 가을 노지삽목을 실시한 결과, 9월 초중순에 하는 것이 뿌리 및 지상부 생육이 양호하고, 월동전 충분한 rosette를 확보 할 수 있어 안정적이었다. 따라서 가을 노지삽목 한계기는 9월 20일로서, 삽목시기가 늦을 경우, 이듬해 봄철 적정 수량을 확보를 위하여 삽수의 수량을 25-30% 늘려 밀식재배하는 것이 바람직하다.
