摘  要：
以‘千禧’和‘早生天鹅绒’为材料研究了日长和覆盖材料对一品红促成栽培的影响。结果表明:短日照处理到苞片转色天数、现蕾到开花天数和短日照处理到开花的天数均以日长11h最长,日长9h和10h差异不显著;开花时的枝长、节数及其增加值也以日长11h最大,9h和10h差异不显著。所以,一品红促成栽培时日长应控制在10h以内。用黑色园艺地布做覆盖材料时一品红开花比用黑色塑料薄膜显著延迟。

摘  要：
Two early varieties of poinsettia,Millennium and Velveteen,were used as test materials and effects of day length and covering material on forcing culture of poinsettia were studied.The results showed that when the day length was 11h,the durations between short-day treatment and bract color change,between in bud and flowering and between short-day treatment and flowering were all the longest,and the shoot length, node number and their increments at flowering stage were also the greatest.When the day length was respective- ly 9 h and 10 h,the differences in the above durations and in the shoot length,node number and their incre- ments at flowering stage were all insignificant.So the day length should be controlled within 10 h in the forcing culture of poinsettia.The flowering of poinsettia was significantly later by the covering of ground cloth than by the covering material of black plastic film.
