Experimental Study on Seedling Raising and Afforestation of Introduced Coastal Pine Seeds in Coastal Areas
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％.
