把原来生长拥挤、较小的幼苗起出来,按一定的株行距栽植到另一块育苗地再继续培育称移植,经过移植的苗木叫移植苗。 一、移植苗的培育技术 从生理上讲,将生长正常的苗木挖出,搬运、再栽植,根系大量受损,破坏了原来地上和地下部分的平衡,而影响了苗木的正常生长,苗木就有死亡的危险。实践证明恢复平衡的主要措施是根据树种的特性,掌握适当的移植期,减少移植时根系受损,适当修剪树冠部分的枝叶,栽后及时灌水等,促进根系和枝叶恢复生长。
The original growth of crowded, smaller seedlings from the line spacing of a certain plant line to another nursery and then continue to cultivate said transplant, transplanted seedlings called transplant seedlings. First, the transplant seedling cultivation technology Physiologically speaking, the growth of normal seedlings excavated, handling, replanting, a large number of damaged roots, destroyed the original balance of the ground and underground parts, and affect the normal growth of seedlings, nursery stock Danger of death. Practice has proved that the main measures to restore balance is based on the characteristics of species, grasping the appropriate period of transplantation to reduce damage to the root system during transplantation, proper pruning canopy part of the crown, timely irrigation after planting and so on, and promote the recovery of root and branch growth.
