雷竹笋重模型研究

Study on the models for shoot weight of Phyllostachys violascens

基于江西省抚州市东乡区200株雷竹笋最大处直径(D)、长度(L)和重量(W)的实测数据,应用回归分析方法对雷竹单株笋重进行拟合,并绘制雷竹单株笋重查询图。结果表明:调查区雷竹单株笋重最优模型为W=16.8264+0.3287 D2L,决定系数为0.9407,经显著性检验达到极显著水平,可用于估算雷竹的单株笋重。

Based on the measured data of maximum diameter(D),length(L)and weight(W)of 200 Phyllostachys violascens shoots in Dongxiang District,Fuzhou City,Jiangxi Province,the models for single shoot weight of Ph.violascens were fitted by regression analysis,and finally the query graph of single Ph.violascens shoot weight was drawn.The results showed that the optimal model of single Ph.violascens shoot weight is W=16.8264+0.3287 D2L,the determination coefficient of model is 0.9407,and reached the most outstanding level through outstanding test.This model can be applied to estimate for single Ph.violascens shoot weight.
