The bulb scales had a higher induction rate of 89.3% to 93.3%, better quality and lower decay rate and the best rooting, in which single-scale reproduction coefficient reached 1.14 to 1.19 when cutting in soil from original environment and peat and pearlite (1:1) as medium under the condition of 25℃ and dark, followed by cutting in peat and sand (2:1) and peat and vermiculite and perlite (1:1:1). There were the highest single-scale reproduction coefficient (1.38) when cutting in sand, but the induction rate was lowest (58.7%). The bulb scales was easy to rot and unfit for use in peat.

以原生土、草炭＋珍珠岩(1：1)这2种基质最好，诱导率达89.3%93.3%，平均每鳞片繁殖小鳞茎数较高，达1.14~1.19个，产生的小鳞茎质量也较好，而且鳞片腐烂率低，生根效果也最好；草炭+河沙(2：1)及草炭+珍珠岩+蛭石(1：1：1)的扦插效果仅次于草炭+珍珠岩(1：1)；河沙扦插鳞片时，平均每鳞片繁殖小鳞茎数最高，达1.38个，但诱导率最低(58.7%)，易造成鳞片干萎，草炭则易造成鳞片大量腐烂，均不宜使用。
