摘要
五个梯度遮光处理忽地笑(Lycoris aurea)生长发育情况。结果表明:20%遮光出葶最早,全光照出葶最迟。花葶长度以40%遮光处理下最长,全光照最短,各处理差异显著。开花率全光照处理最低;40%遮光最高,适度遮光的环境更有利忽地笑开花。不同遮光处理集中开花时间在9月上中旬,遮光处理对开花时间影响不显著。40%遮光处理开花持续时间最长,盛花期一致,花径较大,且叶长度、叶面积、叶片数均表现最好。全光照集中开花时间在10月,说明全光照有一定的延迟花期作用,但花质量不好,花期持续时间不长,展叶时间延迟。随着遮光程度的增加,叶片的叶绿素含量逐渐增加。认为忽地笑为喜中等光照又耐荫的花卉,中等光照强度是忽地笑室外应用的最适光照强度。
Different shading was applied to study the growing development and analyse the effects on golden spider lily（Lycoris aurea）.The results were as follows：the 20% shading appeared scapes at the earliest,and the full exposure was the latest.The 40% shading had the longest average length of scape and the full exposure was the shortest.The effects of shading to the length of scape was significant.Blossom rate of the 40% was the highest;the full exposure was the lowest as well.So,it was more favorable to blossom at shading environment.Almost concentrate time of blossom were in early or middle September under different shading,and the influence was not significant.The 40% shading treatment showed the highest blossom rate,the longest time of lasted-blossom,more consistent of bloom stage,larger flowers and leaves,the more number of blade;However,the blossom under the full exposure was in October,which showed it could certain delay flowering time,but the time of lasted-blossom was shorter,the time of blade-spread out was delay as well as.With shading degree increasing,leaf chlorophyll content increasing gradually.To sum up,it could showed Lycoris aurea was fit for medium,but it was able to endure a shadow environment.The conclusion was the medium illumination intensity was more suitable for Lycoris aurea application outdoor.
