通过对引种沙地海岸松的育苗和造林试验研究,结果表明:在沙地海岸松第一年幼苗期生长中,播种密度对其影响不大,而适度遮荫(80%透光率)有利于海岸松幼苗的生长。沙地海岸松在养分含量高、偏酸性土壤中生长占优势,且在温州地区育苗及造林后的高与地径生长均显著高于蓬莱地区。海岸松容器苗的造林成活率显著高于裸根苗;不同海岸带造林后,其生长速度在海阳市最快,其次是莱州市和烟台市。
The results showed that the sowing density had little effect on the growth of Pinus thunbergii in the first year, but moderate shade (80% light transmittance) had Contribute to the growth of Pinus thunbergii seedlings. Coastal sandy loam had high nutrient content and dominant acidic soil growth, and its height and diameter growth in seedling and afforestation in Wenzhou area were significantly higher than those in Penglai area. The afforestation survival rate of container seedlings was significantly higher than that of bare root seedlings. After afforestation with different coastal zones, the growth rate was the fastest in Haiyang City, followed by Laizhou City and Yantai City.
