长白松在辽西地区引种试验

Introduction trial of Pinus sylvestriformis in west Liaoning

为丰富辽西半干旱地区的造林树种,进行了长白松引种栽培试验,结果表明,在引种地长白松自14年生时开花结实,与当地栽培的樟子松相比,初期生长速度较慢,10年生以后逐渐超越樟子松,年高生长量可达95 cm,且表现出较强的适应性和稳定性。

In order to enrich the afforestation tree species in semi-arid area of west Liaoning,introduction trial of Pinus sylvestriformis was conducted.The results indicated that Pinus sylvestriformis was blooming and seeding since14-yearold.Compared with Pinus sylvestris var.mongolica planted in local area,growth speed of Pinus sylvestriformis was slowerin initial stage,but exceeded Pinus sylvestris var.mongolica gradually in10years.Height increment of Pinus sylvestriformis reached95cm per year,and showed higher adaptability and stability.
