摘要
本文重点研究了丛生竹次生枝的扦插繁殖技术。指出次生枝扦插成活率除因竹种而异之外，主要与下列因素有关：枝龄──６月龄左右的嫩枝扦插成活率可达“６０％～９０％；枝级──一级次生枝扦插成活率约５０％～９０％；二级次生枝降至１５％～４０％；三级次生枝低于２％；扦插季节以春季（３月）最好，成活率为８１．８％，４月以后扦插成活率下降至４１．７％。此外，研究了人工促进次生枝萌发生长，营建采萌圃的技术，其主要措施是：选母竹──一年生健壮竹株，直径２ｃｍ左右为宜。截杆──在小母竹离地１．５ｍ处截断；伤地下茎芽──阻止孕笋，促进萌枝；定──按１．０ｍｘ１．５ｍ株行距将母竹定植于采萌圃；圃地管理。
A description is given of the cuttage of secondary branches of thickly-growing bam－boo, including the selection of cutting and time，and the function of plant growth regula-tors.A technology of establishing cuttings orchard through artificial-growth-enhancedsecondary branches has been developed.The methods applied include the application ofcomplex fertilizer to stimulate branch growth，and the separate cuttage between old andyoung branches.The average survival of cuttings was about 50％ and it might be as high as95.5％.
