遮阴对香水百合生长和开花的影响

目的]研究遮阴对香水百合(Lilium casa Blanca)生长发育的影响,为其在四川地区的引种驯化、规模化栽培种植提供理论依据。方法]以香水百合‘黄天霸’为试材,设置4个遮光梯度,分别是60%、70%、80%和90%,研究了遮阴对香水百合生长和开花的影响。结果]随着遮阴强度增加,株高逐渐变高,叶面积逐渐变大,茎逐渐变细,但茎粗变化不显著。在遮阴60%处理下,‘黄天霸’现蕾期和透色期均提前,较其他处理平均提前3 d,花蕾个数、花径、花瓣长度也优于其他处理,同时花色也更为艳丽、饱满,花期稍长于其他处理1d。结论]因此四川地区香水百合生产最佳遮阴强度为60%。

Effect of Shading on the Growth and Bloom of Lilium casa blanca

Objective] To study the effect of shading on the growth and development of Lilium casa blanca,so as to provide theoretical references for its domestication and large-scale cultivation in Sichuan.Method] With "Huangtianba" as the test materials,four gradient treatments of 60%,70%,80% and 90% shading were set up to study the effect of shading on the growth of Lilium casa blanca.Result] With the increase of shading intensity,the plant grew taller,the leaf area became larger,but the stem was getting slightly thinner.Under 60% shading,both the budding period and bloom period of "Huangtianba" were three days in advance compared with that under other treatments,and the quantity of buds,the diameter of flowers and the length of petals were all better,and the flower color was brighter,the flowering period was one day longer.Conclusion] 60% shading intensity was the best for the production of Lilium casa blanca in Sichuan.
