| 摘 要： | 对受笋万纹象(Otidognathus rubriceps Chevrolot)、一字竹笋象(O.davidis Fairmaire)、大竹笋象(Cyrtatrachelus longimanus Fabricius)危害后断梢毛竹、竹腔注药防治后毛竹、正常毛竹3种竹材进行竹材抗弯强度、抗弯弹性模量和顺纹抗拉强度测定结果表明,与正常毛竹相比较,受竹笋象危害断梢毛竹差异显著,3个竹材物理力学性质指标分别下降了43.79%、39.01%、29.28%,竹腔注药防治后毛竹3个指标下降了13.87%、10.95%、9.01%,但差异不显著,不影响竹材的使用价值. |

| Abstract: | Physical and mechanical properties such as bending strength,bearing elastic modules and tension strength parallel were determined for three kinds of the bamboo woods of Phyllostachys heterocycla var.pubescens,which were injured by Otidognathus rubriceps Chevrolot,O.davidis Fairmaire,Cyrtatrachelus longimanus Fabricius and lost tip,were injected pesticide into bamboo cavity and were normal respectively.Compared to the normal bamboo wood,three index of the injured bamboo wood decreased 43.79%,39.01% and 29.28% respectively,and the injected bamboo wood decreased 13.87%,10.95% and 9.01% respectively.The difference between the injured and the normal bamboo wood is obvious,and injecting insecticide into bamboo cavity doesn't reduce the use value of bamboo wood. |
