云浮市生态景观林带16种植物的早期生长表现

Early growth performance of 16 species of Eco-Landscape forests in Yunfu area

以广梧高速公路云浮段生态景观林带为调查对象,分析不同坡位下16种阔叶树种的早期生长表现,结果表明:木荷(Schima superba)、宫粉羊蹄甲(Bauhinia variegate)和樟树(Cinnamomum Camphor)的造林成活率较高,大叶紫薇(Lagetstroemia speciosa)、木荷(Schima superba)和宫粉羊蹄甲(Bauhinia variegate)的地径增长系数较高,火焰木(Spathodea campanulata)、美丽异木棉(Chorisia speciosa)和蓝花楹(Jacaranda mimosifolia)的树高增长系数较高,大叶紫薇、蓝花楹冠幅较大,总体而言,下坡位生长最好,其次是中坡,最差是上坡。

Sixteen broad-leaved tree species were investigated under different slope positions of Eco-landscape forest belt in Guangwu Highway,Yunfu city. The results showed that S. superba,B, variegata,and C. camphora displayed higher preservation rate. The ground diameter coefficient of L. speciosa,S, superba,and B. Variegata were higher than others. The height coefficient of Spathodea campanulata, Ceiba speciosa, and J. Mimosifolia were higher than others.The L. speciosa and J. Mimosifolia have highest crown. On the whole, The growth traits were the highest at uphill, intermediate at mesoslope and the lowest at downhill.
