杨树造林方法主要是植苗造林和截干植根造林。单纯为了提高造林成活率 ,多提倡截干植根造林 ,仅从提高造林成活率角度分析 ,截干植根造林因成活时需水量少 ,较植苗造林成活率高一些 ,但是对生长影响尚无报道。本试验通过在相同立地条件下 ,进行截干植根和不截干植苗造林进行对?
Poplar afforestation methods are mainly planting seedlings afforestation and truncated stem afforestation. Simply in order to improve the survival rate of afforestation, and more to promote truncated stems afforestation, only from the point of view to improve the survival rate of afforestation, truncated and planted afforestation due to the need to survive less water than seedling afforestation survival rate higher, but no effect on growth Reported. This experiment through the same site conditions, the truncated dry-rooted and non-truncated planting seedlings for?
