荔枝常因幼树花而不实而颗粒无收.糯米糍品种4年生幼树盛花期主干环剥,并保持不愈合至采果.对照树全年根、梢各有3个生长期,环剥树采前无根、梢生长;对照树有4次生理落果峰,环剥树第2、3落果峰不明显,采前落果峰也很低.研究认为荔枝幼树根系的“库”力在竞争中占优势,根与梢的生长相克又相促,果实在竞争中处于劣势,环剥完全抑制了根与梢的生长,使果实在“库”力的竞争中得以转弱为强.
Lychee often due to the young tree flowers and not real but the grain crop failure. Glutinous rice varieties 4-year-old sapling flowering trunk girdling, and remain non-healing to the picking fruit.Control tree annual root, shoot each have 3 growing periods, the ring There was no root and shoot growth before stripping the tree, and there were 4 physiological deciduous peaks in the control tree, and the second and third deciduous peaks were not obvious and the fruiting peak before harvesting was also very low. In the competition, the root of the growth and the phase of g phase and promote the fruit at a disadvantage in the competition, girdling completely inhibited the growth of roots and shoots, so that the fruit in the “library” of the competition for power to weaken strong.
