摘要
采用变温处理水曲柳种子,春季播种,出苗率95%以上;两个年度的平均苗高分别为12.9 cm和15.0 cm,平均地径分别为5.1 mm和6.0 mm;大部分苗木达到Ⅰ、Ⅱ级苗标准,可直接用于造林。
The seed of Fraxinus mandshurica was treated by alternating temperature.The emergence rate was more than 95%when the seed sowed in spring.The average seedling height of two years was 12.9 cm and 15.0 cm, respectively.
