| 中文摘要: |
| 为研究25%氟节胺悬浮剂对荔枝的产量和品质的提高改善作用，连续两年在荔枝秋梢成熟后而冬梢未出时喷施不同浓度的25%氟节胺悬浮剂。结果显示：25%氟节胺悬浮剂能够明显控制和抑制荔枝冬梢的萌发和生长，与对照相比，冬梢的控制率和抑制率分别达到了76.54% ~ 94.34%和90.26% ~ 98.84%；氟节胺对荔枝的增产效果显著，与对照相比，产量增加了116.12% ~ 206.23%；氟节胺对荔枝果实品质无显著提高改善作用。综合考虑，当药液浓度达到500 mg/kg时，各项指标均达到较高水平，且与最大值均无显著差异，因此建议喷施的适宜浓度为333.3 ~ 500 mg/kg。 |

| The objective of this study is to investigate the effect of 25% flumetralin SC on growth, quality and yield in litchi. A series of concentrations of 25% flumetralin SC were sprayed when autumn shoots of litchi matured but winter shoots not outgrown for two years running. The result showed that the number and length of winter shoots significantly decreased after using different concentration of 25% flumetralin SC. Compared with the control, the control rate and inhibition ratio of winter shoots decreased about 76.54% ~ 94.34% and 90.26% ~ 98.84% respectively, whereas the reproduction increased about 116.12% ~ 206.23% . The quality of litchi had no significantly improvement after using different concentrations of 25% flumetralin SC. The physiological indicators of litchi reached the better level and had no difference from the best when using 500 mg/kg of 25% flumetralin SC. Therefore, the concentrations of 333.3 ~ 500 mg/kg were recommended to use in the field. |
