| 摘 要： | 小佛肚竹Bambusa ventricosa多用于盆景制作和园林绿化。研究结果表明:小佛肚竹出笋能力强,无大小年之分,笋期7~10月,达116 d,8月上旬至9月上旬的盛期出笋数占总出笋数的70%以上,而末期历时占笋期的44.8%;竹笋-幼竹高生长时序变化呈“慢—快—慢”的节律,以历时20 d,平均生长量2.60 cm.d-1的高生长盛期最快,阶段高生长量占新竹高度的65.4%;各出笋期的竹笋-幼竹高生长期无显著差异,平均高生长期为62 d,明显少于其他中大型丛生竹种。图1表2参11

| Abstract: | Bambusa ventricosa is an excellent bamboo species which is used for garden landscape and potted landscape.The shooting capacity of B.ventricosa is strong and no off-year of shooting.The shooting period lasts 116 d ranging from July to October.More than 70% shoots emerge at high emergencing shoot stage ranging from the first ten days of August to the last ten days of September.The latest stage takes the percentages 44.8% of the emergencing shoot stage.The height growth of shoots and seedlings presented the "S" type curve with "rapid-slow-rapid" rhythm.Speedy growth stage lasts 20 d with 2.6 cm height growth per day.The biomass of this period takes the percentages 65.4% of seedlings height.There are no differences on height growth of shoots and seedlings among all shoot stages.The average of height growth time is 62 d,which is shorter than that of other sympodial bamboos. |
