杨树速生丰产林营造技术浅探

Discussion on Planting Techniques of Fast growing and High-yielding Forest of Poplar

本文根据密度对比试验和正交试验 ,对包头平原区的 3个主栽杨树品种进行了速生性的比较和分析 ,最后认为 :斯大林工作者杨一级苗以 2 m× 2 m的株行距栽植 ,其椽材生产效果最佳 ;斯大林工作者杨以 4m× 3m的株行距栽植 ,其檩材生产效果最佳。

Based on the density contrasting test and cross test, fast growth of 3 main poplar varieties planted in Baotou flatland are compared and analyzed. The results show that the rafters produced by the first level seedlings of P. pyramidalis × nigra planted in the spacing of 2m×2m are the best; and the purlins produced by P. pyramidalis × nigra planted in the spacing of 4m×3m are the best.
