| 摘 要： | 目的]预测麻竹林分结构特征与产量。方法]通过充分调查麻竹林分结构,对麻竹的产量预测,探讨不同留竹量对麻竹产量的影响,得出最优的留竹方式。结果]麻竹林中胸径整齐度差异显著,立竹密度与立竹胸径差异不显著;同一林分内的不同样地立竹胸径差异不显著;不同麻竹林分类型立竹整齐度差异性显著,立竹均匀度差异不显著。结论]麻竹产量与胸径之间最优的方程为:y=0.14x2.32,相关系数0.98;麻竹在留2株母竹时,获得产量最高。

| Abstract: | Objective] Study on structure characteristics and vield prediction of Dendrocalamus latiflorus Munro.Method] The effect of different quantities of living bamboo on Dendrocalamus latiflorus Munro yield was discussed through surveying bamboo structure characteristics and predicting yield,the best way of leaving bamboo was found out.Result] There were significant differences in DBH(diameter at breast height) and uniformity of Dendrocalamus latiflorus Munro,whereas the differences in density and DBH were none significant;There were none significant differences in DBH of different sample plot within the same sample area.The difference in uniformity was significant,whereas evenness was not significant in different sample area.Conclusion] The effective prediction was established between yield and DBH,and the best equation was: y=0.14x2.32,the correlation coefficient was 0.98;There were the highest yield when the quantity of leaving bamboo was two. |
