This experiment was carried out to clarity the effect of summer softening cultivation on bud yield of Aralia continentalis Kita. Bulbous plant harvested on March 25 and stored in low temperature storage room($0-2^{circ}C$) were transplanted in May, June, July and August. The bulbous plants were grown under black PE film and 50%(T-2250) silver shading nets. The results obtained are summerized as fallows. Harvesting time in Jul. and Aug. transplanting was 15days and was speeling 5days in May transplanting. The accumulative temperature of whole growth period was about $400^{circ}C$. But yield of soft stems in June transplanting was 6.64(ton/ha), which was more than others. High temperature induced low-quality of soft stem in transplanting in July. Net income was 18000(1000won/ha) in transplanting in May or June.
