Preliminary Research on Mixed Stands of Liriodendron chinense etc. with Cunninghamia lanceolata

In order to develop fine broadleaf and precious coaifer commercial woods,Liriodendron chinense (Hemsl.) Sarg,L.tulipifera L.,Sassafras tzumu Hemsl.,Cinnamomum camphora (L.) Presl,Zelkova schneideriana Hand-Mzt,Fokienia hodginsii (Dunn) Henry et Thomas were selected for mixed plantation experiments with Cunninghamia lanceolata (Lamb.) Hook..The measurements for 12 year's growth suggested that C.lanceolata could be selected as an associated species in mixed plantation with each experimental species except Z.schneideriana.The stand of C.lanceolata after 10 year's growth could be cut and used as undersized tree sawtimber,and pure crop of undeveloped species left would grow well.
