Characteristics of Stand Growth Factors of Shoot Producing Dendrocalamus latiflorus Forests with Different Densities
摘要
Abstract
The Dendrocalamus latiflorus bamboo forests for shoot production in the Baisha Base of Yufeng District,Liuzhou City,Guangxi,are selected as the research object.Four stand densities are chosen(A:1 175 plants/ha with a spacing of 6 m×5 m;B:2133 plants/ha with a spacing of 6 m×2.5 m;C:2450 plants/ha with a spacing of 6 m×1.5 m;D:1 950 plants/ha with a spacing of 4 m×5 m)to measure stand factors including diameter at breast height(DBH),tree height,and crown width,aiming to explore the characteristics of stand factors under different densities.The results show that there are extremely significant differences(P<0.01)in DBH,culm height,crown width,leaf length,leaf width,leaf area,and leaf length-width ratio of D.latiflorus under different densities.The bamboo culms in plot C have the largest DBH and height;those in plot A have the largest crown width and leaf length-width ratio;those in plot D have the largest leaf length,leaf width,and leaf area;and those in plot B have the highest evenness index,which is 49.27.Correlation analysis indicates that there is an extremely significant positive correlation between DBH and height,and also between leaf length and leaf width,as well as between leaf length and leaf area.Therefore,appropriate planting densities should be selected according to different cultivation objectives of D.latiflorus forests to promote the efficient cultivation of forests which are used for the Luosifen industry.关键词
