摘要

天山云杉 (Picea screnkianavar. tianschanica)天然分布区的下限海拔 1450～1800m

进行速生丰产造林试验

结果表明

灌丛地横向割灌

纵向割灌和丛植 3种处理效果显著;灌丛地和欧洲山杨 (Pupulus tremula)皆伐地采用大穴整地和丛植

这 2种立地类型15a生的天山云杉幼树树高分别比CK高出40.0%和46.5%

天山云杉在不同立地类型高生长的优劣顺序为灌丛地 >欧洲山杨皆伐地 >欧洲山杨-天山云杉皆伐地。

Abstract

The natural P.screnkianavar.tianschanica forestation on the lower limit of elevation range of 1450～1800 m. The results showed that the effect was significant by the 3 treatments of cross and straight cutting brushes along the mountain slope with motor chain saw and group planting of P.screnkiana var. tianschanica; by big hole-site preparation and group planting in the brush land and trembling poplar clear cutting slash

the P.screnkiana var.tianschanica sampling(15 a) were 40.0% and 46.5% higher than CK. The excellent and poor consequent succession of spruce sampling growing in the different sitetype was brush land> trembling poplar clear cutting slash> trembling poplar> P. screnkiana var.tianschanica clear cutting slash.
