目前,油松受松干蚧危害严重,现已蔓延到沈阳一带;红松材质虽佳,但分布有局限性,大多分布在本溪、抚顺、丹东等地区;樟子松具有抗寒、耐旱、耐瘠薄,又不受松干蚧危害的特性,自一九五五年引入我省,在我区栽培表现生长快、适应性强等特点,已在我区安家落户。本试验依据樟子松上述特性,用樟子松做砧木嫁接红松,扩大红松栽培地域;用油松做砧木嫁接樟子松,提高其抗性,同时也加快樟子松的发展。
At present, Pinus tabulaeformis is severely endangered by Pinus massoniana and has now spread to Shenyang area. Although the Pinus koraiensis material is good, its distribution is limited, mostly distributed in Benxi, Fushun, Dandong and other regions. Pinus sylvestris has the characteristics of cold resistance, drought tolerance, Barren, and not susceptible to the effects of loose scales and scabies, introduced into our province since 1955, growing rapidly in my area cultivation performance, adaptability and other characteristics, has settled down in my area. According to the above characteristics of Pinus sylvestris var. Mongolica, Pinus sylvestris var. Mongolica was used as the rootstock to graft Pinus sylvestris var.mongolica and to expand the Pinus sylvestris cultivation region. Pinus sylvestris var. Mongolica was grafted with Pinus tabulaeformis to enhance its resistance and accelerate the development of Pinus sylvestris.
