摘要:

采用2因子2次回归正交旋转组合设计方法,进行毛竹材用丰产林密度效应定量研究,建立材用毛竹丰产林的产量模型,对立竹密度和平均胸径分别与产量进行回归,建立单因子产量模型和对两因子互作效应进行分析,其最佳竹林密度为4283株/hm2,平均胸径90cm,竹林可获得最高产量54801kg/hm2

关键词: 毛竹, 密度效应, 边际产量

Abstract:

This article studied on Phyllostachys heterocycla cv.pubescens forest density effect for timber use quantitatively by using methods of orthogonal rotation of two factors and quadratic regression, and built bamboo high-yield model for timber use forest, and then analysed the effects of single factor, interaction as well as the interaction of density and D.B.H.on yield. The result showed that the optimum density is 4283 stems per hectare, the mean D.B.H.is 9.0 cm, the highest yield of bamboo forest will be up to 54801 kg/hm2.

Key words: Phyllostachys heterocycla cv. pubescens, Density effect, Limited yield
