Abstract:The distributions of female and male cone, as well as seed cone in thecrown of Chinese fir (Cunningbania lanceolata Lamb. Hook,) trees either fromseed orchard or normal forest land are investigated by growth age section inShangganshan forest farm, Shanggao county, Jiangxi province. Based on this,the information section of flowering and fruiting forecasting the corn cropof a tree is developed by progressive regression. The results indicate that theway of forecasting the cone crop of a individual tree has a higher accuracyand can be used widely.
