赤霉素(GA)自五十年代被广泛重视以来,在柑桔生产上的应用显示了多方面的效应。对花芽形成的影响方面有试验报道。在沙莫蒂甜橙、温州蜜柑、伏令夏橙等品种上经GA处理后显著减少了次年花量。因此,有人认为,如对次年花量能控制到一定程度,可作为克服大小年现象的措施之一。但总的说来,在这方面的试验报道还不多, The application of gibberellin (GA) in citrus production has shown a wide range of effects since it was widely valued in the 1950s. There are experimental reports on the effects of flower bud formation. In Shamo Di orange, Satsuma mandarin, Valsparum orange and other varieties on the GA treatment significantly reduced the next year after the amount. Therefore, some people think that if the next year’s quantity can be controlled to a certain extent, it can be used as one measure to overcome the size-year-old phenomenon. However, in general, there are not many reports of experiments in this area.
