| 摘 要： | 研究表明,当毛竹(Phyllostachys heterocyclacv.Pubescens)对叶斑枯病(Coccostroma arundi-nariae)中度或重度感病时,新竹的直径生长、重量均受到严重影响,成竹的竹壁物质积累下降,感病林分的出笋量大大减少,严重阻碍了毛竹生产的发展.用材林的损失估测模型以逻辑斯蒂模型为最优:L=24.236 1/(1+20.908 1exp(-0.107 1X)];笋用林的损失估测模型以简单线性回归模型为最优:L=5.0209+0.702 9X.

| Abstract: | The results show that when Phyllostachys heterocycla cv.Pubescens are infected with leaf spot blight(Coccostroma arundinariae) at middle or serious level,the diameter and weight growth of one-year-old bamboo and the accumulation of the substance of the stem of grown-up bamboo will decrease.This will impede the development of the production of bamboo seriously.Accordingly,different models of determination of the loss of the disease are made.The logistic model of lumber-producing stand is the best:L=24.236 1/1+20.980 1×exp(-0.107 1X)].The linear model of shoot-producing stand is the best:(L=5.020 9+0.702 9X.) |
