Abstract:
Taking Phragmites australis as the research object,the dynamic changes of growth indicators such as the number of surviving plants,coverage,plant height,plant diameter,number of internodes and leaf spread of each plant,and their photosynthetic characteristics and biomass allocation under the two planting methods of pier lifting and layering were observed,and the principal component and correlation analysis of the growth index of Phragmites australis were carried out,to providing scientific basis and practical guidance for the effective cultivation and scientific management of Phragmites australis.The results showed that the number of surviving plants,coverage,plant height,plant diameter,number of nodes,and number of leaves spreading could reflect the growth of Phragmites australis to a certain extent;and these six indicators were positively correlated.The Phragmites australis growth indicators were different under the two planting modes,which were as follows the values of the coverage,internodes and leaf spread of the pier method were higher;the number of surviving plants,plant height and diameter of the bead method were larger.The photosynthetic rate (Pn),intercellular CO2 concentration (Ci),and transpiration rate (Tr) of Phragmites australis of pier lifting method were larger than those of the layering method,and the differences were more obvious in Ci.The total biomass,stem biomass,leaf biomass and stem-to-leaf biomass ratio of Phragmites australis in two growing modes in a growing season were:pier lifting method>layering method.It was concluded that,in practice,if you want to obtain a higher number of Phragmites australis for introduction and cultivation,you can choose the layering method.If you want to obtain a higher amount of reed biomass for raising livestock,you can give priority to the pier lifting method.
