| 中文摘要: |
| 本试验以30年生国庆1号温州蜜柑 (Citrus unshiu cv. Guoqing No.1) 为材料，在盛花期、和/或盛花后一周、两周喷施不同浓度的乙烯利和萘乙酸，比较不同处理疏花疏果的效果。结果发现：盛花期、盛花后一周和两周喷施乙烯利的疏花效果都很显著，盛花期喷施400mg/L、800mg/L的乙烯利，盛花后一周和两周喷施200mg/L、400mg/L、800mg/L的乙烯利，均能达到完全疏除的效果；盛花后一周喷施不同浓度的萘乙酸有显著的疏花疏果效果，坐果率均低于1%，且浓度为600mg/L时能完全疏除，而盛花后两周喷施萘乙酸只有600mg/L才有显著的疏花疏果效果，且能完全疏除。 |
| 英文摘要: |
| Using 18-year old Guoqing No.1 Satsuma mandarin (Citrus unshiu cv. Guoqing No.1) trees as material, we investigated the effects of spraying different concentrations of ethephon or naphthylacetic acid (NAA) at full-bloom and/or one week after full-bloom, two weeks after full-bloom, respectively on flower and fruit thinning. The results indicated that spraying 400mg/L and 800mg/L ethephon at full-bloom, spraying 200mg/L, 400mg/L, 800mg/L ethephon at one week and two weeks after full-bloom could thin fruits completely at one month after treatment; spraying different concentrations of NAA one week after full-bloom had obvious effect on flower and fruit thinning and the fruit setting rate was less than 1%; moreover, spraying 600mg/L NAA at two weeks after full-bloom could completely remove fruit and/or flower at one month after treatment. |
