摘要
为提高樟子松的造林成活率，在塞罕坝机械林场进行了樟子松塑料膜筒和纸筒护苗防风造林试验，结果可使樟子松春、夏造林成活率提高２０％以上。塑料膜筒护苗秋季不用埋土防风，纸筒后期损坏，秋季需埋土护苗。
In order to improve the survival rate of Pinus sylvestris var. mongolica , afforestation experiments through wind blocking with plostic film tubes or paper tubes were carried out on Saihanba Tree Farm.The results showed that the survival rates of the trees planted either in spring or in summer were both improved by more than 20%.
