【摘要】 通过对江西省14个毛竹主产区毛竹力学性质的试验与研究,结果表明:不同的立地条件对竹材有一定的影响:土壤厚度对最大压缩力、最大剪切力、弯弹模量的影响差异显著;抗弯强度、抗拉强度、抗压强度和压缩模量受立地因子的影响很小;海拔、腐殖质厚、速效K和坡位对力学性质的影响并不明显。有机质和速效P对拉弹模量影响在F0．1水平差异显著;土壤厚度对抗剪强度影响在F0．1水平下显著差异;土壤厚度对最大压缩力、最大剪切力和抗弯弹性模量的影响在F0．05水平差异显著,母岩对最大剪切力在F0．1水平下达显著差异; 土壤质地对弯弹模量在F0.1水平下达显著差异;速效N和母岩对最大压缩力的影响在F0．1水平达显著,土壤厚度对其在F0．05水平达显著差异。更多还原

【Abstract】 Mechanical properties of Phyllostachys pubescens in different site conditions in Jiangxi province were studied. The result showed that; the soil thickness had significant influence on the mechanical properties of the plants in the max pressure-force, the max shear-force and the anti-curved elastic modulus, whereas the anti-bending strength, the anti-extension strength, the anti-pressure strength and the anti-pressure elastic modulus showed a tiny variation in different site conditions. The elevation, humus thickness, effect K and the slope had little influence in the mechanical properties of the plants. The organic materials and effect P had significant influence on the property of anti-extension elastic modulus at the level of F0.1. The soil thickness had significant influence on the property of anti-shears strength at the level F0.1 and on the properties of max-pressure-force, max shear-force and the anti-curved elastic modulus at the level F0.05. The mother rock had significant influence on the property of max shear-force at the level of F0.1. The soil quality had significant influence on the property of anti-curved elastic modulus at the level of F0.1. The effect N and the mother rock had significant influence on the property of max pressure at the level of F0.1, and so did the soil sickness at the level of F0.05.更多还原
