The study on the culture of Lycoris radiata HERB in Medicinal Plant II. The Effect of Shade net on Growth and Bulb Yield

약용식물인 석산의 재배학적 연구 II. 광강도가 석산의 생육 및 인경수량에 미치는 영향

This experiment was conducted to establish shade-method suited to on tile artificial propagation of Lycoris radiata HERB. The ligilt intensity in the native habitatwas 30 kux in March and 3.2 Klux from June to sept. The average light intensityin tile open area was 137 Klux in June. The plant height and number of Ieaves wasgood at the 35% to 55% shadeing net. Bloonling time of Lycoris radiata HERB was inthe last of Sept. Yeild of bulb was increased in 35% to 55% of shadeing net.
