| Abstract: | The research objects were Broussonetia Ipyrifera （ L. ） Vent. in natural forests in Huaxi District of Guiyang , by measuring trunk analysis to study the analytical method of growth characteristics. The results indicated that was Broussonetia lpyrifera （ L. ） Vent fast - growing . 11 - year - old＇ s total diameter at breast height growth was 17.35 cm in diameter. Generally,diameter at breast heiht was about 1.5 cm, height growth was 13.43 m,and the total volume of timber growth was 0. 1572 m3. The fast - growing period for was diameter at breast height growth 5 - 7 years. |
