摘要
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。
Test results of treatment of different concentrations of pac-lobutrazol and different application method to six-year-old satruma trees indicate that all the treatments of three levels of foliar spraying (500, 1000, 1500ppm.) and two levels of soil dressing ( 2 g/plant and 6 g/plant) are obviously effective to inhibit summer shoot growth. The growth value of the treated plants is decresed to 74.0-44.3% of that of the control and the shoot growth in the fall is 1.14-4.14 times as much as that of the control. Moreover, flowers of all the treated trees are increased by 10.7-76.2% than that of the control.lt can be concluded from this trial that the the treatment with 2 g/plant soil dressing is the most effective to inhibit summer shoot growth and promote flowers and foliar spraying with 1000ppm. is the next.
