金佛山方竹在黔中竹海森林公园不同类型林地上的造林效果

Afforestation Effect of Chimonobambusa utilis at Forestland of Different Types in Bamboo Forest Park in Central Guizhou Province

竹是贵阳市的市树,将贵州省的特色资源金佛山方竹推广应用于黔中竹海森林公园,对体现贵阳市市树竹的价值具有重要意义。文章在黔中竹海森林公园中选择不同类型的林地(火烧迹地、落叶阔叶林下、常绿针叶林下及林间空地)进行金佛山方竹造林试验,结果表明,金佛山方竹造林宜选择2年生实生苗,适宜的乔木林郁闭度为0.3~0.5,栽植后前6年,每年抚育2次,第7年以后可以采笋,笋产量约167~261 kg/667 m;。研究表明,金佛山方竹在黔中竹海森林公园适合的林地中能够生长良好,既能造景又能发展林下采笋经济,值得进一步推广栽植。

Bamboo is a city tree of Guiyang.It is of great significance to apply the Chimonobambusa utilis,a special resource of Guizhou province,to Bamboo Forest Park in central Guizhou to embody the value of the city bamboo of Guiyang city.In this paper,different types of forestland(burned area,deciduous broad-leaved forest area,evergreen coniferous forest area and forest space)in Bamboo Forest Park are selected for C.utilis afforestation.The results show that 2-year-old seedlings should be selected for C.utilis afforestation,with the suitable canopy density at 0.3-0.5;in the first 6 years after planting,the bamboo forest should be annually tended twice,and the shoots can be harvested in the seventh year with the shoot yield at about 167-261 kg/667 m;.The results indicate that C.utilis can grow well in the suitable forestland of Bamboo Forest Park in central Guizhou,which can be used not only for landscaping,but also for understory economic development,and the species could be further promoted for planting.
