福建沿海湿地松防护林造林生长及林下生物多样性分析

为探索湿地松在福建沿海地区防护林营造过程中的适应性和生长趋势,对莆田沿海湿地松3~10年生幼林的胸径、树高的生长发育规律及林下植被多样性进行了调查研究,结果表明:使用培育6个月的湿地松容器苗,采取科学规范的造林措施,设置密度2505株·hm^-2,湿地松的适应性强,成活率高,能速生丰产,10年生的林木平均胸径达13.11±0.09 cm、树高达8.58±0.03 m,林下的生物多样性高,物种近20种。

Investigation on Afforestation Technique and Growth Status of Coastal Pinus elliottii in Fujian Province

In order to explore the adaptability and growth trend of constructing Pinups elliottii protection forests in coastal areas of Fujian Province,the growth and development rules of DBH,tree height and diversity of understoryvegetation of 3-10-year-old young forest of the coastal Pinups elliottii in Putian were studied.Result shows that:The container seedlings of wetland pine cultivated for 6 months were adopted,and scientific and standardized forestation measureswere adopted,density(2505·hm^-2)was set.Pinups elliottii has a strong adaptability in the coastal area of Putian Region,with a high survival rate and rapid growth and high yield.The 10-year-old Pinups elliottii has an average DBH of 13.11±0.09 cm and an average tree height of 8.58±0.03 m.The forest has high biodiversity and many species.There are nearly 20 species.
