Application of Azolla in Ecological Agriculture from Azolla Event

This paper begins with the azolla's function in global climate event at the Eocene-Oligocene transition: from greenhouse to icehouse,and points out its great application potential for future ecological agriculture including as production raw material of high quality agricultural products,as plant for improving agriculture ecological environment and preventing heavy metal pollution,and as pioneer plant for exploring outer space.It also puts forward that the future research should focus on energy-saving,environment protection,using azolla as organic fertilizer source,leading in exogenous gene,and studing sporocarp production technology,so as to fully display the function of azolla spore in future ecological agriculture.
