摘　　要：分别以0.4、0.8、1.3、1.8 m的树冠高度对珍珠番石榴成年树进行回缩修剪,以不修剪为对照,探讨对珍珠番石榴的树高、冠幅、总枝数、30 cm以上长的枝数、各级分枝数、枝长、枝粗的影响。建议回缩高度以0.8-1.3 m为宜。Effects of different height of retraction on the tree height, crown diameter, total branch number, the number of shoots in the length of above 30 cm, the branching number on different level, branch length and diameter were studied in the paper. Retractive pruning was carried out on the adult trees of pearl-guava compared with no pruning used as a control. The trees were pruned back to the average crown height of 0. 4, 0. 8, 1.3 and 1.8 m respectively. 0.8 and 1.3 m were recommended as the suitable height of retraction.
