Abstracts:The authors made a significance of difference test among randomized block and comparative analysis on the seedling stage, growth increment according to oriented cultivation and agroforestry construction direction. The results showed that differences among seedling stage were significant, the differences among the height increment of trees were not significant after afforestation during 2003～2006, the differences among diameter increment were significant, and after five years the differences among the height increment of trees were significant. Combined with comparison, the results showed that poplar of Lushan and Zhonglin-2025 were the best. At the same time, the better varieties were evaluated by using collateral inclination and damage rate by pests as reference index. Preferred varieties for appropriate forest networks were Zhonglinmeihe, Linchanglv, euramericana “108”. Varieties suitable for oriented cultivation of plain planting were Zhonglin-2025. While Lushan can be planted in wider area.
