| 摘 要： | 以3、6、9、11 a生的高纺锤形苹果树为试材,测定了不同树龄的枝量、树体结构及产量。结果表明:不同树龄的干周、冠径、树冠体积、树叶密度随着树龄的增加而增加,天空可视度则随着树龄的增加而减少;不同树龄的中、长枝比例均较小,短枝比例大。其中3 a生树长枝比例较大,短枝比例较小,6、9、11 a生的枝类比相差不大。3、6、91、1 a生总枝量分别为28.1、87.8、119.4、110.4万条.hm-2;3、6、91、1 a生树产量分别为5 760、25 8005、6 220、57 645 kg.hm-2,表现为在结果初期,随着树龄的增加产量迅速增加,到结果盛期时产量趋于稳定。综合分析表明苹果高纺锤形具有结果早,且不同树龄段树势较稳定,产量高等优点。

| Abstract: | Tall-spindle shaped apple trees with 3,6,9,11 years old were used as experimental materials,parameters such as branch number,tree body structure and yield were measured.The results showed that the stem circumference,canopy diameter,canopy volume and leaf density increased as the increase of tree ages,whereas DIFN decreased with the tree age.Each age group had a small proportion of middle and long branches but a large proportion of short branches.Trees of 3-year-old had a large proportion of long branches an... |
