用多效唑不同浓度及不同施用方法处理六年生温州蜜柑的试验结果表明:叶面喷施500、1000、1500ppm及土施2克/株、6克/株五个处理均对夏梢抽发有明显的抑制作用,其夏梢抽发量为对照的74.0～44.3％。而秋梢抽发量增加到对照的1.14～4.14倍。同时,各处理树翌年花量增加为对照的110.7～176.2％。从本试验初步得出,以土施2克/株对温州蜜柑控梢促花效果最佳,其次为叶面喷布1000ppm。 The experimental results of different concentrations of paclobutrazol and different application methods on six-year-old Satsuma showed that foliar spraying 500,1000,1500ppm and soil application 2g / plant, 6g / plant five treatments showed obvious Of the inhibition, the summer shoots the amount of the control 74.0 ~ 44.3%. The amount of autumn shoots increased to 1.14 ~ 4.14 times the control. At the same time, the amount of flowering in the next year increased by 110.7 ~ 176.2% of the control. It is concluded from the preliminary experiment that soil 2 g / plant has the best effect on promoting the flowering of Satsuma mandarin, followed by foliar spraying at 1000 ppm.
