摘要
对紫花芒果进行３种程度的修剪试验结果表明，轻剪和中剪树抽梢少，碳水化合物积累早，花期较早，持续７２ｄ。重剪处理把初花期推迟２０ｄ，盛花期推迟了８ｄ，原因是推迟了树体碳水化合物的积累期，重剪树果实大小和可食部分比例未受影响，只是产量和商品果率有所降低，通过调整修剪的时期、程度和方法能改善重剪处理树的结果状况。
Pruning experiments were conducted in five year old mango trees Mangifera indica L. cv. Zihua on Oct. 3, 1993 and repeated on Sept. 20,1994. Results showed that heavy pruned trees flowered 20 days later than light and medium pruned trees, and that full bloom was delayed by 8 days with heavy pruning, but the crop level decreased probably because of delayed accumulation of carbohydrate reserves by strong regrowth after heavy pruning, resulting in a decrease of flowering shoot rate . No fruit quality decrease was observed with heavy pruning. Crop level of heavy pruned trees in 1994/1995 was improved as the result of practicing earlier and less severe pruning.
