| Abstract: | Plant’s form,biomass,lawn coverage,density,leaves withered rate and Chlorophyll content were determined by continuing(6 months)over shading treatment(shade rate reached 96%).The results demonstrated that the height,length and breadth of leaf were increased to a certain degree through shading treatment;the content of Chlorophyll a and Chlorophyll b in leaf was increased too,but the value of Chlorophyll a/b was decreased;the leaves withered rate was increased,and most of the dry leaves gather at 0～5 cm of the bottom;biomass and density were decreased.Zoysia matrella,Oplismenus compositus var.owaterii,Cyrtococcum patens A.Camus and Ottochloa nodosa still maintain a certain green coverage of 0%,25%,40% and 55% respectively. |
