桥山林区红松引种试验初报

Reliminary Report on the Introduction Test of Korean Pine in Qiaoshan Forest Area

为解决林区栎类生长率低、栎类与油松混交造成油松生长不良的情况,笔者在桥山林区进行红松育苗及造林试验,探索了在桥山林区引种并发展红松的可能性,为提高林区生物多样性提供了理论依据。试验结果表明,林冠下植苗造林三年存活率为85.2%,在桥山林区引进红松苗木进行林冠下造林是可行的。

In order to solve the reality of low growth rate of Quercus,and poor growth of Pinus tabulaeformis mixed Quercus in forest areas,seedling cultivation and afforestation experiments of Pinus koraiensis in Qiaoshan forest area were explored the possibility of introducing and developing Pinus koraiensis in Qiaoshan forest area,a kind of theoretical basis for improving the biodiversity in forest area.The experimental results showed that the three-year preservation rate of seedlings cultivation and afforestation under the forest canopy is 85.2%.Therefore,it is feasible to introduce Pinus koraiensis for afforestation under the forest canopy in the Qiaoshan forest area.
