The research about the properties and utilization of fast growing trees have caused wide public concern with the background of the severe shortage of forest and the urgent need for its protection.According to the recent reports,we have only exploited few kind of fast growing trees, and utilize grade and utilization ratio were lower,so that in this paper,based on analyzing growth speciality and tiny structure and fibre shape and chemical composition and physics properties of fast growing trees species Zenia insignis Chun.. The results showed that it is feasible to use Zenia insignis Chun, as raw material to manufacture flame retardant MDF and flame retardant PB and flame retardant LVL,its physical and mechanical properties,surface physical and chemical properties and flame retarding properties are accord to the correlative standard.Zenia insignis Chun.popularize planting and comprehensive utilization exploitation that is of especial importance to industry.
