| 摘 要： | 海滨林场建场以来营造的大面积青杨派杨树人工林，因沙地瘠薄、病虫为害而生长严重不良。但利用这些杨树伐根改接毛白杨却长势旺盛，１７ａ生林分平均胸径已达２０ｃｍ，树高已达２０ｍ以上。利用此技术，海滨林场已改接毛白杨林达１３０余公顷。

| Abstract: | Because of poor soil,pests and diseases,the plantations established with the pop-lars trom Tacamahaca section in Haibin tree farm were inferior in growth. However,the plan-tations regenerated from those by grafting Populus tomentosa onito the stumps grow well.For the regenerated plantations of 17 years old,the average diameter at breast height reached20cm,and the tree height 20m,With the technique,this tree form has regenerated more than130hm2 of Populus tomentosa. |
