| 摘 要： | 此项试验旨在探讨防止满天红梨采前落果的有效途径。试验结果表明：采果前一个月对树冠喷施10~30mg/L的2,4-D、50~200mg/L的GA3和10~40mg/L的NAA对防止满天红梨采前落果均具有极显著作用。在不同浓度处理中，2,4-D和NAA均以20 mg/L的处理效果最好，坐果率分别比对照提高了13.7个百分点和16.8个百分点，GA3以100 mg/L的处理效果最好，坐果率比对照高14.8个百分点。 |

| Abstract: | The effective approaches to prevent the preharvest fruit drop of Mantianhong Pear were studied in this experiment. The results of the experiment showed that before Mantianhong Pear ripened one month, 2,4-D spray at 10~30mg/L, GA3 spray at 50~200mg/L or NAA spray at 10~40mg/L all prevented the preharvest fruit drop of Mantianhong Pear remarkably. In different thickness disposals, 2,4-D and NAA spray at 20mg/L both had the best purpose, and the fruit-setting rates were increased by 13.7% and 16.8% respectively compared to that in the control. GA3 spray at 100mg/L had the best purpose, and the fruit-setting rate was increased by 14.8% compared to that in the control. |
