在中国自50年代就已开始了利用容器培育林木曲木。有限的资金几乎只消耗在利用地方资源以手工制作育苗容器方面。最通用的是纸制或聚乙烯管筒状容器。其形状与大小类似于其他国家用于生产苗木的纸制或聚乙烯容器。圆柱状容器的缺点是它使侧根围绕主根卷曲生长。根系卷曲被认为是幼树不稳定(即死亡的可能性)的潜在原因,尤其是容易引起松树和桉树的倒伏以及容易造成在树干基部弯曲。苗根的弯曲也会限制主根的径向生长,据 In China since the 1950s has begun to cultivate the use of container tree wood. Limited funding is almost exclusively spent on the use of local resources for hand-made nursery containers. The most common is a paper or polyethylene tubular container. Its shape and size are similar to paper or polyethylene containers used in other countries for the production of seedlings. The disadvantage of a cylindrical container is that it curls the lateral roots around the main root. Root curl is considered as a potential cause of young tree instability (ie the possibility of death), especially prone to pine and eucalyptus lodging as well as easily causing bending at the base of the trunk. The bending of seedling roots will also limit the radial growth of the main root, according to
