据《Scientia Horticulturae》(2012.11.2)的一篇研究报道,来自美国佛罗里达大学的研究人员设置了3个试验,研究了淹水前摘叶处理对鳄梨短期淹水后树体胁迫、成活率和恢复状况的影响。每个试验中的树均分为淹水处理和不淹水处理两个处理组。试验1中淹水的树进行2个修剪处理:修剪去除冠层2/3;不修剪(对照组)。试验2中,淹水的树进行3个处理:从底部向上除去冠层2/3的叶片(2/3LR);不去叶,叶施化学
According to a study published in Scientia Horticulturae (2012.11.2), researchers from the University of Florida set up three experiments to study the effects of leaf pick-off before immersion on the avocado tree’s short-term waterlogging stress and survival rate And the impact of recovery status. The trees in each experiment were divided into two treatment groups: flooded and non-flooded. The primed tree in Experiment 1 was subjected to two pruning treatments: pruning to remove the canopy 2/3; no pruning (control group). In Experiment 2, flooded trees were treated three times: 2/3 of the canopy leaves (2/3 LR) were removed upward from the bottom;
