卷丹百合鳞片育苗技术研究

为探索适于卷丹百合鳞片扦插育苗的有效方法,对在不同基质上(悬空海绵组10个处理,盆栽组6个处理)培养80d后鳞片的生长进行研究.结果表明:(1)悬空海绵组在海绵筒中加入的粉状活性炭高度越高鳞片生长状况越差,其中活性炭高度为0.2~0.3cm时鳞片的生长指标最优,生根率为86.33%,叶片抽生率为83.33%,生根系数为2.33,增殖系数达2.97,腐烂率仅为3.33%.(2)悬空海绵组与盆栽组在细沙中加入活性炭的量越多鳞片长势越差;基质相同时,前者培养的鳞片生长状况优于后者.采用悬空海绵法培育卷丹百合鳞片,操作简单、鳞片生长好,增殖多,是其鳞片扦插育苗的一种新方法.

Breeding Technique of Lilium lancifolium Scales

In order to explore effective method of scale cutting for Lilium lancifolium Thunb,the growth of scales were measured after culturing 80 days on different substrates which divided into two groups,one was water culture with hanging sponges(10 treatments),the other was potted culture(6treatments).The results showed that:(1)during water culture with hanging sponges,following the height of powdered activated carbon added in sponge cylinder increased,the growth became worse,when the height of activated carbon was 0.2-0.3cm,the growth of scales was the best,which rooting rate,sprouted leaves rate,rooting factor,multiplication coefficient,and decay rate were 86.33%,83.33%,2.33,2.97,3.33%,respectively.(2)Both on water culture with hanging sponges and potted culture,the amount of activated carbon in the activated carbon and sand mixtures was higher,the growth of scales was worse.When the matrix was same,the growth of scales on water culture with hanging sponges was better than on potted culture.Applying water culture with hanging sponges method to breed scale of Lilium lancifolium Thunb operate easily,grow well and proliferate highly,it is a new method for lily scales cutting.
