摘　　要：[目的]为赤水市竹产业的发展提供理论指导。[方法]对赤水市楠竹林场种苗繁育基地几种引种竹的生长情况进行调查,并按不同年龄及平均胸径选取2株样竹作为标准木,测定其竹杆和竹枝叶鲜重、树高、胸径、节长、壁厚等。[结果]麻版1号、大叶龙竹、大绿竹胸径较大,而妈竹、撑麻8号胸径最小;大绿竹、大叶龙竹株高较高;沙罗单竹、粉单竹竹节较长;大绿竹、麻版1号和大叶龙竹壁较厚;大绿竹、吊丝单竹和大叶龙竹产量较高(均在105.00 t/hm2以上),粉单竹产量最低(仅为49.65 t/hm2)。[结论]各引种竹的生长状况均较好,其中大绿竹、吊丝单竹和大叶龙竹的产量较高,可在进一步试验的基础上大面积推广。[Objective] The investigation aimed to provide theoretical guidance for the development of bamboo industry of Chishui City.[Method] The growth condition of several introduced bamboo species in the seedling propagation base of bamboo forest management area of Chishui City was investigated and 2 bamboo plants were selected as sample tree according to different ages and average diameters at breast height.Then the fresh weights of bamboo pole and branches and leaves,tree heights,diameters at breast height,node length and wall thickness of tested bamboo plants were measured.[Result] The diameters at breast height of Dendrocalamus latiflorus Munro×Dendrocalamus hamiltonii Nees et Arn.ex Munro No.1,Dendrocalamus barbatus var.internodiiradicatus and Dendrocalamopsis daii were bigger and that of Bambusa boniopsis and Bambusa pervariabilis Mc-Clure ×Dendrocalamus latiflorus Munro No.8 were smallest;the plant heights of D.daii and D.barbatus were higher;the bamboo nodes of Schizostachyum tunghomii and Bambusoideae cerosissima McClure were longer;the bamboo walls of D.daii,D.latiflorus Munro×D.hamiltonii Nees et Arn.ex Munro No.1 and D.barbatus were thicker;the bamboo yields of D.daii,Dendrocalamopsis vario-striata and D.barbatus were higher,all of theirs were over 105.00 t/hm2 and that of B.cerosissima McClure was lowest,being only 49.65 t/hm2.[Conclusion] The growth condition of all the introduced bamboo species was better and the yields of D.daii,D.vario-striata and D.barbatus were higher.These 3 bamboo species could be popularized in large area on the basis of further experiments.
