摘　　要：选用尿素、施易乐、NAA+BA、TMN-6等4种制剂对富士苹果进行了疏花疏果试验,结果表明:以0.5 mg/L TMN-6制剂的处理效果最好,座果率为27.9%;在盛花期喷布TMN-6,不仅能显著提高疏花效果,且使侧花的结果率显著降低,提高了单果率和中心果率(89.22%和100%);同时TMN-6处理对叶、生长点以及果实生长和果实品质均无不利影响。Four agents, including urea, Shi Yi Le, NAA ＋ BA, TMN-6 were used for Fuji apple flower and fruit thinning. The results showed that the effect treated with 0.5 mg/L TMN-6 was the best, the fruit setting rate was 27.9%. Spraying TMN-6 in full bloom not only increased the effect of flower and fruit thinning, hut also significantly reduced fruit setting rate of lateral flowers and inproved single fruit rate and central fruit rate were improved （ 89.22% and 100% ）. At the same time, the TMN-6 treatment had no negative effects on leaf and stem primodium and fruit development and quality.
