摘要: 对水曲柳与赤杨、水曲柳与长白落叶松,分别采用5行、8行带状混交和10株x lO株块状混交方式,按不同立地条件进行造林,以研究各自的混交效果。结果表明,混交林可以明显地提高各树种造林保存率和生长量;在几种混交类型中,以5行带状混交效果最显著,可以有效地提高林地生产力,其次为8行带状混交,lO株×10株块状混交效果稍差。

Abstract: According to different sites,Fraxinus mandshurica and Agnus japonica,F.mandshurica and Larix olgensis mixed forest were planted either 5,8 lines belt-mixing or 10×10 trees plot-mixing for studying mixing effects.The results indicated that:survival rate and growth increment of tree species in mixed forest were increased significantly.The mixing effect of 5 lines belt-mixing had the most significant effect among the several mixing types.in which the productivity of forest land was increased effectively.The next better one is 8 line belt-mixing,10×10 trees plot-mixing was not so effective.
