丛生竹次生枝的扦插繁殖

CUTTAGE OF SECONDARY BRANCHES OF THICKLY-GROWING BAMBOO

    摘要
  • 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;定植--按1.0m×1.5m株行距将母竹定植于采萌圃;圃地管理。

     

    Abstract: A description is given of the cuttage of secondary branches of thickly-growing bamboo, including the selection of cutting and time, and the function of plant growth regulators. A technology of establishing cuttings orchard through artificial-growth-enhanced secondary branches has been developed. The methods applied include the application of complex fertilizer to stimulate branch growth, and the separate cuttage between old and young branches. The average survival of cuttings was about 50% and it might be as high as 95.5%.
