中文摘要：

以南逗迈4号芒果树为试材,采用不同栽培措施进行产期调节试验研究.春季重剪配合多效唑溶液土壤浇淋、KNO3叶面喷施处理的末级梢平均开花率为54.6％,平均单株产量为21.6 kg,单纯KNO3叶面喷施处理末级梢平均开花率为13.9％,平均单株产量为12.9 kg.试验结果表明,南逗迈4号芒易于催花,采用春季重剪配合多效唑溶液土壤浇淋、KNO3叶面喷施处理可获得较高的开花率,套黑色双层纸袋可使果皮干净细滑,商品外观好,具有良好的产期调节生产应用前景。

英文摘要：

Using mango cv. Nam Dok Mai No. 4. as material, the experiment was carried out to study the effects of different cultivation practices on fruit maturity regulation. The results showed that hard pruning in spring combined with paclobutrazol soil-drenching and KNO3 fo- liar-spraying had an average flowering rate of 54.6 %, average yield per tree of 21.6 kg. While only KNO3 foliar-spraying had an average flowering rate of 13.9 %, average yield per tree of 12.9 kg. Mango cv. Nam Dok Mai No. 4 was easy to induce flower. Hard pruning in spring com- bined with paclobutrazol soil-drenching and KNO3 foliar-spraying could obtain high flowering rate. Bagging fruit with black double paper bag could make fruit peel smooth and improve out- look of fruit. It has good prospects in off-season production.
