Abstract：The cultivar‘Tianhong 2 ’ Fuji /SH40/Malus robusta was used to study the effects of combined application of chemical and organic fertilizers at different ratios on the apple tree structure and fruit quality . The results showed that spur and foliage branches occupied the highest proportion of tree branch classes , which was followed by the medium branches;the proportion of long and leggy branches were the lowest .Dif-ferent fertilization treatments had different effects on apple fruit quality .After basal application of 28 800 kg organic fertilizer per 666.7m2 , topdressing 32 kg urea and 61 kg organic fertilizer per 666.7m2 in March and topdressing 61 kg organic fertilizer per 666.7m2 and foliar spraying 1%urea in September could obtain higher fruit weight, color index, clean index, contents of soluble solids and soluble sugars , and medium fruit firm-ness and titratable acid , so better comprehensive effects could be obtained under this treatment .
