扁秆藨草地上部分与地下球茎生长的关系研究

Study on the Relationship between Aboveground Parts and Underground Corms of Scirpus planiculmis

目的:通过对扁秆藨草地上部分与地下球茎生长的关系研究,为湿地恢复和白鹤保护工作提供科学依据。方法:在扁秆藨草生长的成熟期,在研究样地内随机选取扁秆藨草,测其地上部分高度,密度及地下球茎干重等。结果:模拟出扁秆藨草地上部分与地下球茎生长的关系。结论:模拟结果和图像显示,扁秆藨草地上部分和地下球茎的增长会出现起伏,这是由于扁秆藨草在不同时期自身的营养流向不同所造成的;模型能够有效的描绘扁秆藨草地上部分与地下球茎生长的动态关系,对扁秆藨草生长的调节提供科学的依据。

Objective: The relationship between the growth of aboveground parts (APs) and underground corms (UCs) of Scirpus planiculmis was studied to provide a scientific basis for the wetland restoration and white crane protection work. Method: Scirpus planiculmis was randomly selected at the research plots during their mature stage with the height and density of the APs and the dry weight of the UCs measured. Results: The relationship between the growth of APs and UCs of Scirpus planiculmis was simulated. Conclusion: Results show that the growth of APs and UCs was fluctuated, which is due to the different flow direction of the nutrition in Scirpus planiculmis at different times. More- over, the model can effectively describe the dynamic relation between the growth of APs and UCs and can provide ref- erence for the growth regulation of Scirpus planiculmis.
