为了解决油松长期受松干蚧的为害和生育不佳问题,1973年我们在辽阳地区引种了樟子松(Pinus sylvestris var.mongolica Litv.)并在灯塔县华子林场水库工区建立了种子园,历经13年,证明樟子松在辽阳地区生长良好,具有抗寒、耐干旱、耐瘠薄而又不受松干蚧为害的特点,很有发展前途。 1 概况种子园位于参窝水库山地,海拔120m,年降水量797.3mm,年活动积温3464℃,最高气温38.5℃,最低气温-38.8℃,年平均气温
In order to solve the long-term problem of Pinus tabulaeformis and its poor fertility, Pinus sylvestris var. Mongolica Litv. Was introduced in Liaoyang in 1973 and a seed orchard was established in Huazhilin Reservoir Reservoir Area of Beacon County. 13 years, proven Pinus sylvestris grows well in Liaoyang, with cold, drought, barren and not susceptible to the characteristics of pine dry scale, great prospects for development. 1 Overview Seed Park is located in Shenwo reservoir mountain, elevation 120m, the annual rainfall of 797.3mm, the annual accumulated temperature 3464 ℃, the highest temperature 38.5 ℃, the lowest temperature -38.8 ℃, the annual average temperature
