一些果农对不易成花结果的幼旺乔化红富士苹果树,连年在主干上进行环剥,虽然促花效果显著,但弊病很多。 (1)弱主枝先成花,不利于树势平衡和扩冠。在主干上连年环剥,树冠中的弱主枝先成花结果,而抽生的新梢少且弱,形成早衰。而强壮主枝,成花较少,越长越旺。这样就不利于树势平衡和扩冠成形。
Some fruit growers are not easy to flower results of flourishing Qiaohua Fuji apple trees, year after year in the main trunk girdling, although significant flower promotion effect, but a lot of ills.
