Abstract

This study was conducted to investigate the effect of ridge height (10 cm, 20 cm, 30 cm, and 40 cm) on the soil physical property, the growth and flowering characteristics of Gypsophila paniculata (cv 'Bristol Fairy') in the subalpine area. As ridge height got higher, the daily soil temperature, the soil moisture content, soil hardness, bulk density, and solid phase ratio were decreased, but porosity ratio was a little increased. In summer and autumn cultivation the blooming of ridge height 30 cm and 40 cm was slightly delayed, but their root activity, cut flower width, and yield were better than those of 10 to 20 cm ridges. And the mortality ratio of plants, rosette formation rate, and nonpaniculata inflorescence rate became lower.

준고냉지에서 안개초 'Bristol Fairy'를 실험재료로 이랑높이를 10, 20, 30, 40 cm로 하여 토양 물리성, 생육 및 개화특성 등을 조사하였다. 주간 지온, 토양 수분함량, 토양 경도, 용적밀도 및 고상률은 이랑이 높을수록 낮고, 공극률은 약간 높아지는 경향이었다. 여름과 가을 절화작형에서 30 cm, 40 cm 이랑에서 개화는 약간 지연되었으나, 뿌리활력, 화수폭과 절화량은 우수하였다. 여름을 경과하면서 발생한 고사주율 및 로젯트 발생률, 비원추화서률 등 생리장해 발생도 낮아지는 경향이었다.
