摘　　要：为筛选适宜早酥梨疏花疏果的化学药剂,选取六至七年生早酥梨为试材,研究在不同时期Ca+NAA、Ca+SNA、Ca+Sevin、Ca+6-BA药剂处理对早酥梨果实坐果率和品质的影响。结果表明:在盛花期1次疏花+盛花后10d疏果时Ca150倍液+SNA 40mg·L-1表现最好,坐果率为32.04%。在初花期、盛花期2次疏花+盛花后10d疏果时喷施Ca150倍液+Sevin 2.0g·L-1药剂处理表现最好,坐果率为23.63%。In order to screen out the suitable chemical treatment for Zaosu pear flowe and fruit thinning,we use6-7 years old pear trees as test material to study the effects of Ca＋NAA,Ca＋SNA,Ca＋Sevin and Ca＋6-BA treatments at different stages on the fruit setting and quality.The results showed that the treatment 2（Ca 150 times＋SNA 40 mg·L^-1）was the best in the treatment of thinning flower at flowering stage and thinning fruits at 10 days after flowering stage,and the fruit set rate was 32.04%.In the early flowering stage,the treatment 7 of Ca 150 times＋ Sevin 2.0 g·L^-1 was the best in the treatment 2 times flower thinning at early flowering stage and flowering stage and thinning fruits at 10 days after flowering stage,and the fruit setting rate was 23.63%.
