摘　　要：通过对黄土高原地区优质高产苹果树体结构各项指标与产量之间关系的调查分析,得出了该区域红富士苹果获得优质、高产应具备的各项指标范围及其与产量的相关方程。其中盛果期植株的干高在70～78 cm之间,相应干径为10～13 cm,冠幅介于180～275 cm。系统分析得出了产量(y)与干高、干径、冠幅(x)均呈显著正相关关系,方程分别为:y=2.418 8x-68.547(干高);y=14.062x-55.977(干径);y=0.597x-48.394(冠幅);产量与短枝比例也呈显著正相关,方程为y=30 716x-13 822。Relationship between the architecture indices and yields of the Red Fuji apple trees with high apple quality and high yields were investigated. Ranges of different indices and the equations representing the relationship between these indices and yield were deduced. It was found that the preferable trunk height of the plant in their full fruit period were 70-78 cm, 10-13 cm for trunk diameter, and 180-275cm for tree crown. The trunk height was significantly and positively correlated to apple yield with a related equation y=14. 062x-55. 977, so were the diameter of trunk and yield, with a related equation of y=0. 597x -48. 394. Crown was positively correlated to the yield with an equation of y=307 16x-13822.
