Study on Triploid White Popular “Forestpaper”Industrialization

Zhao Yonggang Gao Keshu Zheng Hong(Shanxi Forestry Research Institute,030012 Taiyuan)  
On the basis of study of triploid Chinise White Popular's growth characters,key techniques of ‘forest-paper’ industrialization were analysed synthetically.The results are as follows:(1)There are significant differences in d.b.h increaments between species.(2)The popular are more suitable for planting on farmland forest-network than on road forest-network,the volume of wood within farmland forest-network being twise as high as of the latter.(3)Analyses on 27 indexes with the popular such as high-yield property,resistance,and wood characters showed that it's a ideal material to make paper.Multiple place G×E interaction tests indicated that its genetic stability in growth is not good,and the varieties should be monitored by trace.(5)Rational rotation determined is that 5 a in Henan,7a in Hebei,Beijing,and Shandong,5 a and 9 a in Shanxi.(6)In the ‘forest-paper’ industry structure,the proportion of paper,forest,and seedling in annual profit and tax is 40∶20∶1。
