摘　　要：以2年生天红1号/SH40/八棱海棠为试材,研究了不同生长调节剂(多效唑、生长调节剂PBO、氨基酸肥)的不同浓度处理对矮砧密植苹果幼树的控梢效果及成花的影响。结果表明,与对照相比,100倍PBO和500倍多效唑处理的红富士苹果,其控梢和成花效果最好;氨基酸处理对控制新梢生长效果不佳,但有利于当年花芽的形成,60倍氨基酸处理成花效果最好。Two-year-old"Tianhong No.1"/"SH40"/"Baleng"crabapple were used as materials to study the effects of different growth regulators(paclobutrazol,PBO,amino acids)with different concentrations on shoot control and flower formation of young apple trees planted on dwarf rootstocks.The results showed that compared with the control,the shoot control and flowering effect of 100 times PBO and 500 times PP333 were better.Amino acid treatment has poor effect on controlling the growth of new shoots,but it was beneficial to the formation of flower buds in the same year,and 60 times amino acid treatment has the best effect on flower formation.
