Abstract: Oligostachyum scabriflorum is an excellent native bamboo species in Fujian,which is dual-use in both shoots and materials.Also,its rhizome,bamboo shoots and the growth rhythm of young bamboo is similar to single-axis scattered bamboo.The vertical distribution of bamboo rhizome mostly comes within 20 cm in the soil range,and the rhizome system which keeps the length between 4 to 15 meters accounts for 78.1%.Shooting period relatively concentrates in the middle ten days and the last ten days of March,and the weights of single shoot are as follows:peak >initial >late.The process from young bamboo shoots unearthed to growth stopped in height can be divided into four stages including initial stage,rising stage,peak and late.Oligostachyum scabriflorum is shallower than bamboo in vertical distribution of bamboo rhizome,while earlier in shooting period.Moreover,there is not obvious major or minor year in bamboo shooting.In sum,Oligostachyum scabriflorum kept high value in development and utilization.According to the biological characteristics,bamboo rhizome growth and law of bamboo shooting and growing,the appropriate technical measures can be took on reforming barren wild bamboo grove in the natural distribution area to bamboo forest.And the bamboo forest would be grand just only 2-3 years later.
