搭设障蔽控制樟子松风蚀沙埋危害的效果

Control Effect on Wind Erosion and Sand Cover by Building SandBarrier for Pinus sylvestris var. mongolica Plantation

  • 摘要: 以樟子松为对象探讨搭设沙障控制风蚀沙埋危害的效果。结果表明:搭设与未搭设沙障的造林保存率存在显著差异,搭设沙障可使造林保存率高达100%;搭设与未搭设沙障的生长量也存在显著差异,搭设沙障可使树高、地径、树冠生长量分别提高554%、666%和607%;搭设沙障为樟子松的形态建成创造了良好的环境条件,树干弯曲、风倒及枯黄现象明显减少。

     

    Abstract: The control effect on wind erosion and sand cover by building sandbarrier was studied by taking Pinus sylvestris var. mongolica as planting tree species. The results showed that building sandbarrier could promote the survival rate of the plantation up to 100%, which was significantly higher than that of the control. There were also significant differences in the growth rate of the Pinus sylvestris var. mongolica plantation between building the sandbarrier and the control. The experiment showed that building the sandbarrier could promote the average sapling height, basal diameter and crown growth by 55.4%, 66.6% and 60.7% respectively compared to the control. Sandbarrier building provided the morphology construction of the Pinus sylvestris var. mongolica saplings with much better environment that significantly reduced the phenomena such as trunk bending, wind throw and drying up of the brnaches and turning yellow of the leaves due to the wind damage.
