摘要:
对陇县八渡林场2003年引种美国花旗松不同绿地、密度造林(定植)生长状况与相同条件的油松进行了跟踪调查。结果表明：美国花旗松(Douglas fir)苗期、幼树期生长量均小于油松，却因适生性极强且树形优美而成为陇县首选优势绿化树种。We did a survey on different green belt and growth status of density afforestation of American Douglas fir introduced in 2003 and Chinese pine in the same condition. The results show that the increment of American Douglas fir in seeding and sapling stage is smaller than Chinese pine, while it has strong adaptability with graceful body which makes it become the preferred greening tree species in Long County.
