总结出白皮松大苗栽植及养护管理的关键技术和措施。大规格,特别是未经移植或断根处理的白皮松,在移植过程中根系会受到较大的损伤,吸水能力大大降低。树体因供水不足,水分代谢失去平衡而枯萎,甚至死亡。因此,保持树体水分代谢平衡是栽植养护管理、提高移植成活率的关键。 Summed up the white pine seedlings planting and conservation management of key technologies and measures. Large size, especially the white pine that has not been transplanted or cut off roots, will be greatly damaged in the process of transplantation, and the water absorption capacity will be greatly reduced. Tree due to lack of water, water metabolism imbalance and wilt, or even death. Therefore, to maintain the balance of water metabolism of trees is planting conservation management, improve the survival rate of transplantation key.
