摘　　要：通过对吊丝单竹、云南甜竹、大头典竹在相同抚育措施下出笋规律调查,结果表明:吊丝单竹出笋早,出笋量大,平均达37.05支/丛,但出笋总重量低,平均仅25.25kg/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42.2kg/丛,大头典竹出笋产量仅次,达40.1kg/丛。从方差分析上看,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。Based on the investigation on the regulation of shoot appearance of Dendrocalamopsis vario -striata,D.beechyana var.pubescens and Dendrocalamus brandisii with the same cultivation,the results show that:The shoot of Dendrocalamopsis variostriata appeared earlier than the other species and the quantity is larger(an average of 33.7 shoot every cluster),but the gross weight is low(an average output of only 25.25 kg every cluster) and Dendrocalamus brandisii are late coming into bamboo shooting,but the shoot yie...
