以天红2号／SH40／海棠为试材，研究了不同有机无机肥配施对苹果树体结构和果实品质的影响。结果表明：所有施肥处理的树体枝类比以叶丛枝和短枝的比例最高，其次是中枝，长枝与徒长枝的比例最低；不同施肥处理也对果实品质产生不同的影响，其中处理12，即在试验初期666．7m2基施有机肥28800 kg的基础上，每年3月份追尿素32 kg、有机肥61 kg及9月份追施有机肥61 kg、叶面喷施1％尿素，果实单果重、着色指数、光洁指数、可溶性固形物及可溶性糖含量均高于其它施肥处理，果实硬度及可滴定酸适中，综合效果较好。

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 .
