%X 以5 a生的‘嘎啦’苹果/M26自根砧为试材，在其初花期（全树5%花开放）后的第2天和第4天2个时期各喷施1次甲酸钙（5 g/L、7.5 g/L、10 g/L）、萘乙酸（10 mg/L、15 mg/L、20 mg/L）、大豆油（30 g/L、40 g/L、50 g/L），研究3种疏花剂对‘嘎啦’苹果的疏花效果和对果实感官品质的影响。结果表明，各疏花剂对果实主要感官品质负面影响。从花序坐果率、花朵坐果率、单/双果率及空台率等指标综合评价，疏花效果较好的是质量浓度为10 g/L的甲酸钙、10 mg/L的萘乙酸及30 g/L的大豆油。<br>The M26 self-rootstocks from 5-year-old ‘Gala’ apple trees were used as materials in this experiment. In the second and fourth days after early flowering (5% flowers into blooming), the apple trees were sprayed with calcium-formic acid compound (5 g/L, 7.5 g/L,10 g/L) , naphthalene acetic acid (10 mg/L , 15 mg/L , 20 mg/L ) and soybean oil (30 g/L, 40 g/L, 50 g/L) to investigate the thinning effects of the flower thinning agents on fruit quality. The results showed that all flower thinning agents had no negative effect on the sensory quality of ‘Gala’ apple. Based on the inflorescences of fruit setting rate, flower fruit rate, single/ double fruit rate, empty fruit rate and other indicators, the 10 g/L calcium-formic acid and 10 mg/L naphthalene acetic acid and 30 g/L soybean oil were proved to be the better agents for thinning flowers.
