广竹的生物学特性及栽培技术研究

对广竹的生物学特性及栽培技术研究结果表明:广竹的出笋历期较短且非常集中,出笋高峰期集中在4月上旬,出笋数量占全期出笋总数的62.7%;幼竹高生长及枝条生长曲线均呈"S"形,遵循慢—快—慢的节律;此竹种属于混生竹,可移竹繁殖和埋鞭繁殖,前一方法的繁殖效果较好,成活率可达60%,而埋鞭繁殖效果相对较差,成活率只有38%,最佳繁殖时间宜在12月下旬至次年2月进行;根据其各生长阶段的生长规律、无性繁殖栽培技术以及生产实践,提出了主要栽培技术措施。

Biological characteristics and cultivation technology of Pseudosasa longiligula

It is a study on biological characteristics and cultivation technology of Pseudosasa longiligula.The results showed that:its shooting period was short and centralized.The shooting fastigium period was in early April,accounting for 62.7% of the total amount of emerging shoots.The growth curve of high and branch of young bamboo showed the model of"S"growth type,following the rhythm of"slow-fast-slow".P.longiligula was a kind of monopodial bamboo which had two propagation.The cane with branch layering was the best which survival rate reached above 60%,and the cane with shoot layering only had a survival rate of 38%.The best propagation time was from late December to next February.In the study of growth rhythm,asexual propagation technology and production practice,we present the cultivation technology of P.longiligula.
