| 摘 要： | 通过对采用截冠和留冠两种类型苗木进行杨树造林后的生长情况调查得知:苗木留冠与截冠对造林成活率没有影响。对林木生长影响较大,留冠苗林分平均树高4.9m,胸径4.8cm,分别比截冠苗木林分平均树高、胸径大1.8m和0.6cm,且留冠苗林相整齐、林木长势良好。

| Abstract: | Growth of two types of seedlings of topping and full crown for planting poplar were investigated.Results showed that whether topping or full crown had no effect with survival rate,but had significant effects on growth of stand.The average-height of stand of seedlings was 4.9m and DBH of that was 4.8cm.The average-height of stand and DBH of the full crown was 1.8m and 0.6cm bigger than topping seedlings.Forest form of full crown seedlings were kept in good order and the forest grew well. |
