摘要
本研究对引种烟台多年海岸松的结实种子进行研究,与进口海岸松种子进行对比,并采用这些结实种子进行育苗及造林研究,得出结论:引种海岸松后结实种子在千粒重、发芽情况方面要优于进口的海岸松种子;引种海岸松后结实种子培育一年生苗存在二次生长现象,且苗高、地径生长表现优于进口种子育苗;引种海岸松后结实种子两年生苗在丘陵壤土区造林形态指标最优,在海防林过渡区域沙壤土造林成活率最高,低山区造林成活率最低;引种海岸松后结实种子培育三年生土球苗在海防林林缘处生长最好,成活率达到75％,裸根苗不宜沙区造林.
Abstract
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％.
