Effect of Different Stubble Height Oenanthe Javanica(Blume) DC Floating Bed Systems on Biomass and Water Environment
摘要
Abstract
Oenanthe javanica( Blume)DC floating beds with different cutting heights were emPloyed to examine their Purification effects on water quality in five successive exPerimental Period. When the exPeriment finished,Crown root ratio is 0. 92 ,the ground dry biomass is greater than the ground dry biomass indicated that a large Part of the material and energy were used to root system in order to get more nutrients from the water. There was no significant difference between the average root length, the average root length,the treatments of non harvest treatments and different treatments;There was no significant difference between the biomass and the root system of different stubble height treat-ments. Different exPerimental Period,the PH value and dissolved oxygen content in the floating bed water tank shown the oPPosite trend with the average temPerature of the floating bed water tank, which reflects the close association among PH,dissolved oxygen content and water temPerature. The dissolved oxygen content and PH value difference in last two cycles is greater than the first two cycles between blank control and floating bed system reflected that the floating bed system becomes more significant in the Process of water Purification effect.关键词
