北固山湿地野生虉草生物量的研究

Studies on Biomass of the Wide Phalaris arundinacea L at Beigu Mountain wetland

对北固山湿地野生虉草的株高、茎高、叶龄、生物量等进行了研究,结果表明,虉草的株高和茎高的变化呈现出近“S”型的生长曲线,叶龄与株高和茎高均呈一元线性显著的正相关关系,生物量的变化与生育期关系密切。

Shoot height,stem length,leaf age,biomass of wide Phalaris arundinacea L were studied. The main results are as follows：The change of shoot height and stem length appear “S” curve,there was hightly significant positive correlations between leaf age and shoot height and leaf age and stem length, which could be described by linear regression equations,the biomass changes with the growth and development period obviously.
