苦竹地下竹鞭结构生长规律调查

Investigation on the Growth Law of Underground Bamboo Rhizome Structure of Pleioblastus amarus

通过设立标准地对苦竹地下竹鞭、地上竹高、胸径等因子进行调查,了解苦竹地下竹鞭的结构、生长规律以及在土层中分布情况,并分析苦竹生物量与竹高、胸径等林分各因子的相互关系,采用线性回归和幂函数方程对其生物量进行数学模型拟合,讨论并论述了改善林下竹鞭结构的生长发育规律和提高苦竹生物量的指导方法,从而为苦竹丰产林培育技术研究提供科学的理论依据。

Through the investigation on the factors of Pleioblastus amarus underground bamboo rhizome,aboveground bamboo height,dbh,etc.,this paper found out the structure,and growth law of Pamarus underground bamboo rhizome,as well as the distribution situation of it in the soil layer.It discussed and dealt with the growth and developmental laws,and the guiding method of raising Pamarus biomass,which therefore provided the scientific theoretical foundation for Pamarus high yield forest cultural technical study.
