不同分布格局的梁山慈竹产量差异分析
The Yield Difference Analysis of Different Distribution Patterns of Dendrocalamus farinosus
摘要
Abstract
The investigations of the Dendrocalamus farinosus distribution have shown that Dendrocalamus farinosus in south Sichuan has a wider distribution,and its main distribution patterns can be divided into three kinds:scattered or individual grove,small pieces of a few groves,and concentrated expanse of groves.Different distribution forms exhibit a greater crown root ball area ratio difference.The individual grove pattern has the maximal crown root ball area ratio.DBH can be gotten by means of regression analysis,and the usable rod weight regression model is W=0.102029 * D2.388139 [W means the usable rod weight(kg),D means diameter(cm)].Dendrocalamus farinosus yield differences are relatively great,and through the cluster analysis,Dendrocalamus farinosus yield can be divided into three categories:high,medium and low yield.The output of three different distribution patterns from large to small is as follows:small pieces of a few grovesconcentrated expanse of grovesscattered or individual grove.The main reasons for the discrepancy are the site condition and stand density.关键词
