摘　　要：对太岳林局青岗坪林场3块不同遮荫覆盖条件下,2年生辽东栎播种育苗地苗木生长状况进行了调查,结果表明,3种不同遮荫覆盖条件下苗木生长指标具有显著性差异。遮荫覆盖度0.73样地苗木平均苗高、地径分别为遮荫覆盖度0.34样地的1.46倍和1.38倍;为无覆盖样地(对照)的4.38倍和2.75倍。遮荫覆盖度0.34样地的苗木平均苗高、地径分别为对照的3.0倍和2.0倍。The growth status of 2-year-old Quercus liaotungensis seedlings of 3 sowing nursery sites under different shading and covering conditions in Qinggangping forest farm of national forest administration bureau of Taiyue mountain was investigated.Results showed that the differences in growth indexes of seedlings under 3 different shading were significant.The average height and ground diameter of seedlings in the plot with 0.73 shading coverage were 1.46 times and 1.38 times of those in the plot with 0.34 shading coverage,which 4.38 times and 2.75 times of those in the plot without shading(control).The average height and ground diameter of seedlings in the plot with 0.34 shading coverage were 3.0 times and 2.0 times of those in the control.
