芬兰近几年来,特别是在林业生产上,已逐步地用容器苗代替裸根苗植树。容器苗的特点是其根系用纸筒或泥制外壳保护,植树时根系不受损伤,而幼苗造林后仍能不间断地继续生长。这里介绍的是用纸筒育苗的方法,纸筒用特殊的纸制成,并被排列成蜂窝型结构的箱体。为适应各种育苗和造林方法所采取的不同设备及各树种的不同育苗周期,容器纸筒有几种型号和尺寸规格。
In recent years, Finland has gradually replaced the bare root seedlings with container seedlings, especially in forestry. Container seedling is characterized by its roots with a paper tube or mud shell protection, when the roots are not damaged trees, and afforestation seedlings continue uninterrupted growth. Introduced here is a method of raising seedlings using a paper tube made of a special paper and arranged in a honeycomb structure box. In order to adapt to different seedling and afforestation methods adopted by different equipment and different seedling cycle of each species, there are several types of containers and size specifications.
