带岭林区小黑杨引种及大面积山地人工造林

Introduction and afforesting large area of Populus simnii×P.nigra in Dailing forest upland

黑龙江省带岭林业实验局1979年对小黑杨进行引种育苗,1980年开始进行大面积山地人工造林,面积达400hm2之多。引种至今20多年,已与小兴安岭阔叶红松林区生态环境相适应,成为一个新的生态型。小黑杨与本地多种树种混生,形成了以小黑杨为主的"人天"混交林,实现了早期速生丰产,并有效地抑制了杨树病虫害及树木生理性灾害的发生,为阔叶红松林培育后备森林资源、营造速生丰产用材林增添了新的阔叶树种和可靠的生产模式。

An introduction trial of Populus simnii×P.nigra was conducted in Dailing Forestry Experimental Bureau, Heilongjiang Province, China in1979. Presently, the afforesting large area upland that began in1980 has reached 400 hm^2 above, a new ecotype has become because the platation is suited well to ecological environment of the Mt.Xiaoxing'an broadleaved/Korean pine forest. This species has mixed by many native species, and an artificial and natural mixed forest with the characteristics of fast-growing and high-yield early and high resistance to poplar pests and physiology disaster has come into being.
