| 为研究125克/升氟节胺乳油对柑橘的控梢保果作用，连续两年在柑橘树春梢老熟夏梢未抽时喷施不同浓度的125克/升氟节胺乳油。结果显示：125克/升氟节胺乳油能够明显控制和抑制柑橘夏梢的萌发和生长，与空白对照相比，夏梢的控制率和抑制率分别达到了21.8% ~ 51.6%和32.4% ~ 46.5%，座果率也提高了49.1% ~96.9%,增产5.8%以上。125克/升氟节胺乳油对柑橘有一定的保果和增产作用，推荐使用剂量为有效成分125~166 mg/kg，稀释倍数为1000~750倍，于柑橘树春梢老熟夏梢未抽时喷施1次。 |

| The objective of this study is to investigate the effect of 125g/L flumetralin EC on shoots growth and yield in citrus. A series of concentrations of 125g/L flumetralin EC were sprayed when spring shoots of citrus matured but summer shoots not outgrown for two years running. The result showed that the number and length of summer shoots significantly decreased after using different concentration of 125g/L flumetralin EC. Compared with the control, the control rate and inhibition ratio of summer shoots decreased about 21.8% ~ 51.6% and 32.4% ~ 46.5% respectively, whereas the rate of fruit-set increased about 49.1% ~96.9% . The production of citrus increased more than 5.8% after using different concentrations of 125g/L flumetralin EC. Therefore, the concentrations of 125~166 mg/kg of 125g/L flumetralin EC were sprayed when spring shoots of citrus matured but summer shoots not outgrown in the field. |
