Wang Hu · Journal of Liaoning University · 2014
Through the study of the growth status of 9a Populus( Populus alba L. × P. talassica) under the pruning measures,w hich provides theoretical basis for Karamay to cultive stem form high-quality w ood. In the same pruning intensities( i. e. w eak pruning),selecting 3 strains of Populus,in accordance w ith stem analysis' steps,interception of disc to obtain each age segment data of trees height,DBH,volume. In the w hole grow th season,the total increment of height,DBH,volume maintains rapidder grow th. The mean annual increment is slow,but the current annual increment is quickly. The Populus increment of volume does not appear peak,themean annual increment and the current annual increment are not intersect,it dosen't achieve the age of quantitative maturity. The results show that the trunk of Populus is straight,the local environment suitable for their grow th.
