| 摘 要： | 对吊丝单竹、云南甜竹、大头典竹在相同抚育措施下出笋规律进行调查，结果表明：吊丝单竹出笋早、数量多，平均达37．05支／丛，但出笋总重量低，平均仅25．25／丛，云南甜竹、大头典竹出笋迟，但云南甜竹的笋总产量最高，达42．2／丛，大头典竹出笋产量次之，达40．1／丛。方差分析表明，吊丝单竹与云南甜竹、大头典竹间存在1％极显著水平。从出笋的月规律变化上看，7月下旬和8月中旬均是3种竹子出笋高峰期，而7月中旬和8月上旬均出现出笋低谷期，8月中旬过后均出现出笋逐渐减少趋势，吊丝单竹、大头典竹9月下旬产笋仅零星出现，云南甜竹出笋则在9月下旬仍达到一个小高潮，而后出笋逐渐停止。

| Abstract: | The investigation on the shooting law of Dendrocalamus brandisii,D.Beechyana and D.variostriata under the same cultivation was conducted. The results showed that D.vario-striata put out shoots earlier than the others with a large quantity（an average of 33.7 shoots every cluster）, but the gross weight is low, only 25.25kg every cluster on avarage.D.brandisii and D.beechyana were late in their shooting, but with higher shoot yield, respectively 42.2kg and 40.2kg every cluster on average for D.brandisii and D.beechyana.The variance analysis indicated that there is the remarkable difference （P〈0.01） between D.vario-striata and D.brandisii and D.beechyana.The monthly shooting indicated that the late July and the middle of August is a peak of shooting for the three bamboos, and in the middle of July and the early August appeared a valley of the bamboo shooting. After the middle of August, the quantity of shoots gradually decreased. And in the late September,D.vario-striata and D.beechyana put out very few shoots,while D.brandisii still experienced a small peak of shooting and then gradually stopped shooting. |
