platycladus orientalis 解釋
側柏
  1. In different phases of development, vegetation systems in this region have changed from pioneer herbage species initially recovering in abandoned cropping lands ( bothriochloa ischemum, artenmisia giradii and stipa bungeana, artenmisia sacrorum, spodiopogen sibiricus and sophora flavecens, themeda japonica, and arundinella anomala ) to secondary shrubs ( hippophae rhamnoides, sophora viciifdia, and ostryopsis davidiana ), early forest community ( populus davidiana, betula platyphylla and platycladus orientalis with arbors or shrub assembling ), and finally liaotungesis community as the mature forest. in this study, soil profiles ( 0 - 5, 5 - 15, 15 - 25, 25 - 35, 35 - 50 cm soil layers ) were selected from typical vegetation systems representing for vegetation successions in the region

  7. 1. forests drought resistance the roots of pinus tabulaeformis, platycladus orientalis and robinia pseudoacacia were wrapped by plastic film, then the dry environment was made. the tests showed that the photosynthetic rate of p. orientalis was higher than that of p. tabulaeformis, but the transpiration was opposite. after one year of treating, photosynthetic rate of p. tabulaeformis reduced 55. 1 %, p

    測定結果表明,在相同乾旱的條件下,側柏的凈光合速率始終大於油松,而蒸騰速率則相反,在乾旱脅迫的第2年,油松光合速率比第一年降低了55 . 1 ,側柏降低了45 . 6 ,刺槐降低了56 . 2 。
