摘要

19941996 年在福建南靖县进行麻竹( Dendrocalamus latiflorus Munro ) 扦插苗造林和移栽母竹造林试验, 扦插苗造林发笋数比移栽母竹造林发笋数多 0.25 /, 新竹直径大 1.21 cm 插苗造林后, 当年萌动新竹越多, 新竹直径呈增大的趋势, 随着新竹萌发的先后顺序, 扦插苗造林的新竹平均直径也有相应增大的趋势移栽母竹造林当年, 新竹的大小受新竹数和母竹直径的影
响显著
, 新竹直径与母竹直径呈正相关, 新竹越多, 新竹直径呈减小的趋势, 其新竹平均直径随萌发先后也呈依次减小的趋势
 

Abstract

Test on different planting modes of Dendrocalamus latiflorus Munro showed that the number of bamboo shoo ts growing from D . latiflorus forest planted by cuttage nursery stock is 0 .25 individual/clump more than that by transplant maternal bamboos ;the diameter of new bamboo of the former is 1 .21 cm bigger than that of the later.In the first year after plantation by cuttage nursery stock, the more new bamboo sprout from every clump, the bigger the diameter of new bamboo is, and so it is with the sequence of the sprouting of new bamboo .But in the first year after plantation by transplant maternal bamboos, the size of new bamboo was affected distinctively by the number of new bam boo and the diameter of maternal bamboo, the diameter of new bamboo correlates positively to the diameter of maternal bamboo but negatively to the number of new bamboos, the average diameter of new bamboo tends to decrease w ith the sequence of the sprouting .The co nclusio ns can provide directio ns fo r determination of planting modes and management in the first year after plantation of  D . latiflorus .
