毛竹实生苗竹鞭不同鞭节数量的繁殖效应试验

phyllostachys edulis with Different Number of Rhizome segments

摘要:

以毛竹苗圃残余竹鞭段为材料,采用 3 节、6 节、9 节、10~12节和 13~15节的竹鞭进行埋鞭繁殖,通过调查分析 苗圃起苗后不同鞭节数残余竹鞭分布情况,研究不同鞭节数量对鞭段成活率、竹苗高度影响,为毛竹苗圃残余鞭段再育苗 和快速繁殖提供理论依据和技术参考。 结果表明:9鞭节的竹鞭数量最多,10~12鞭节成活率和竹苗高度最高。 在选用苗 圃残余竹鞭段繁殖毛竹时,综合考虑竹鞭来源、成活率和生长量等因素,选择鞭节数为 9 节以上的竹鞭为宜,可以在短时间 内繁殖出大量优良竹苗且高大,有利于降低育苗成本,缩短育苗周期。

Abstract:

In order to provide technical support For reproduction oFPhyllostachys edulis nursery rhizome segments, the laying-rhizome propagation was carried out with 3, 6,9, 10~12 and 13~15rhizome segment. Through investigation and analysis oFdistribution oFdiFFerent number oFrhizome segments the eFFects oFdiFFerent number oFrhizome on the survival rate oFrhizome segments and height oFP. edulis seedlings were studied. The results showed that number oFrhizome seg- ments at 9 segments was the highest, the survival rate at 10~12 rhizome segments and the height oFP. edulis seedlings were the highest. when selecting the residual rhizome segments in the nursery For breeding P. edulis, considering the source , survival rate and growth oFrhizome segments, it is appropriate to choose the rhizome segments with more than 9 rhizome segments, which can breed a large number oFFine P. edulis seedlings in a short time and is tall, which is conducive to reducing the cost oFbreeding seedlings and shortening the cycle oFbreeding seedlings .
