杨树是灯塔县西部平原沿河区营造速生丰产林的最佳树种,而利用“鲁×山”杨树营造速生丰产林则是优中选优。从1988年春开始引进“鲁×山”杨树营造连生丰产林,经多年观察,该树种很适于本区栽培,株型好,抗病虫能力强,适生范围广,且生长速度快。1988年4月造林,1991年8月调查,3.5年生平均胸径16.74cm,最大胸径20.Ocm,平均树高11.2m,最高13.4m,最大单株材积为0.2204m~3,是目前灯塔县杨树品种中生长量最大的一个无性系。
Poplar is the best tree species for fast-growing and high-yield forests in the coastal plain along the western plains of Beacon County.

After years of observation, the tree species is suitable for cultivation in this area with good plant type, strong resistance to pests and diseases, wide range of suitable habitat and fast growth rate . April 1988 afforestation, 1991 August survey 3.5 years average diameter at breast height 16.74cm, maximum diameter at breast 20.20cm, the average height 11.2m, the highest 13.4m, the largest single plant volume of 0.2204m ~ 3, is the current Beacon County Yang One of the largest growing clones of tree species.
