糙花少穗竹是福建优良乡土竹种,笋材两用,其竹鞭、竹笋、幼竹生长节律与单轴散生竹毛竹相似。竹鞭垂直分布多数在土层20 cm范围,4~15 m长的鞭系占78.1%,发笋期较集中在3月中下旬,单个笋重为盛期笋> 初期笋> 末期笋。从笋出土到幼竹高生长停止,可分为初期、上升期、盛期和末期。但竹鞭垂直分布比毛竹浅,出笋期比毛竹早,且出笋没有明显的大小年,具有较高的开发利用价值。在自然分布区可根据其生物学特性、竹鞭生长与发笋成竹规律采取相应技术措施,垦复改造荒芜野生竹林,2~3年即可郁闭成林。

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.
