移植大树桩时,尽可能带土坨,但是大树桩的吸收根仍然多数失去,留下的老根再生能力差,新根生发慢,吸收能力难以恢复,虽然截枝去叶,但树桩仍然要蒸腾大量水分。当供应(吸收)水分数量小于消耗(蒸腾)水分时,就会导致树桩脱水而死亡。为了维持大树桩移植后水分供应与消耗的平衡,常采用外部给水(土壤浇水和树桩喷水)措施,但是往往效果不佳,甚至造成渍水烂根。如果采用树体内给水的输液新技术,就可解决移植大树桩水分供需矛盾,从而促其成活。现介绍其技术
When transplanting large stumps, soil lumps are carried as much as possible, but the majority of the absorbed roots of the large stumps are still lost. The old roots left behind have poor regenerative ability. The new roots grow slowly and the absorption capacity is difficult to recover. Transpiration of large amounts of water. When the amount of water supplied (absorbed) is less than the consumption (transpiration), it can cause the stump to dehydrate and die. In order to maintain the balance between water supply and consumption after large tree stump transplanting, external water supply (soil watering and stump sprinkling) measures are often used, but the results are often not good and even cause root rot. If the infusion of water in the tree body with new technologies, we can solve the contradiction between supply and demand of transplanting large stumps to promote their survival. Now introduce its technology
