苹果砧木根系的局部修剪,促进了更强旺的和机能上活跃的根系的形成:根系的增压活动增加了,而且在很大程度上是活跃性根压,而不是渗透性根压的增加.由于地上部受到暂时的抑制而导致新根系的形成。在苹果根系修剪的当天,根系的增压性活动减弱,但被剪的根系在长度上是不均衡的.伤流液的供应量和活跃性压力折算成根群的单位则增加了.根系水分的增压现象,在维持植株水分、保证供应的正常水平方面起着重要作用.这一点也反映在植株的生长 Partial pruning of the roots of apple rootstocks promotes the formation of a more vigorous and functionally active root system: increased root activity and, to a large extent, active root pressure rather than increased osmotic root pressure. On the ground by temporary inhibition caused the formation of new roots. On the day of pruning, root activity was weakened, but the root system was unbalanced in length, and the amount of fluid supply and active pressure were converted into root units, and root moisture The supercharging phenomenon plays an important role in maintaining plant moisture and ensuring the normal supply level.This is also reflected in the growth of the plant
