在黄土高原旱地条件下富士苹果适产与品质关系试验表明 ,在通常管理水平下 ,0 .3kg/ cm2 树干截面时产量 ,品质表现最好 ,单果重 195 g,34t/ hm2 ,树体氮、磷、钾含量适中 ,果实外观着色良好 ,内在品质亦最佳 ,应为最佳留果量。留果量大于或小于 0 .30 kg/ cm2 树干截面情况下 ,产量下降 ,抗性亦随之下降 The relationship between fitness and quality of Fuji apples in the dry land of the Loess Plateau showed that under the normal management level, the yield and quality of the trunk section of 0.3 kg / cm2 were the best, the fruit weight was 195 g, 34 t / hm2, nitrogen, Phosphate, potassium content is moderate, the appearance of the fruit coloring is good, the inner quality is also the best, should be the best retention of fruit. Yields were greater or less than 0.30 kg / cm2 Trunk sections, yield decreased, resistance also decreased
