In this study,seed seeds after many years,Contrast with the characteristics of imported coastal pine seeds,and use these seed seeds for seedling breeding and afforestation research,The conclusion is as follows:the introduced coastal pine seeds are better than the imported coastal pine seeds in terms of 1000-grain weight and germination;After the introduction of coastal pine seed cultivation of annual secondary growth of seedlings,And the seedling height,the ground diameter growth performance is better than the imported seed seedling raising;The optimal morphological index of annual seed growth in hilly loam area,The survival rate of sandy loam is the highest in the transition area of coastal defense forest;Growing best at the edge of haicoastal forest,The survival rate reached 75％.
