| 摘 要 【目的】解析矮化处理对香蕉的生长和产量影响，为提高香蕉单位面积产量和种蕉效益提供理论依据。【方法】以中秆香蕉品种桂蕉5号、桂蕉7号为试材，研究不同矮化次数对两代蕉农艺性状和产量性状的影响。【结果】D82药剂矮化处理1次使桂蕉5号、桂蕉7号一代蕉株型变紧凑，单穗重及单位面积产量与对照差异不显著，假茎高度较对照极显著降低37.4、36.1cm，株产为25.9、27.0kg，亩产（种植密度为145株/667m2）为3.75、3.91t；二代蕉株型、产量与对照差异不显著，假茎高度比对照降低5.0、9.8cm，株产为27.5、28.2kg，亩产（留芽密度为145株/667m2）为3.99、4.23t。矮化处理2次，桂蕉5号、桂蕉7号一代蕉株型变更紧凑，假茎高度较对照极显著降低62.1、41.4cm，株产为25.1、23.8kg，显著减轻9.39、13.77%，亩产（种植密度为145株/667m2）为3.64、3.46t，较对照减产9.45%、显著减产13.5%；二代蕉株型仍表现紧缩，而产量与对照差异不显著：假茎高度比对照降低20.7、22.3cm，株产为29.1kg、28.2kg，亩产（留芽密度为145株/667m2）为4.22、4.09t。【结论】中秆香蕉品种桂蕉5号、桂蕉7号适当密植后易获得高产，且综合两代蕉农艺性状和产量性状来看，矮化处理显著影响了一代蕉的农艺性状和产量，如在台风多发地种植，建议只做1次矮化处理。 |

| Abstract 【Objective】To analyze the effects of dwarfing treatment on the growth and yield of bananas, and to provide theoretical basis for improving banana yield per unit area and planting efficiency of bananas. 【Method】Medium stem banana varieties Guijiao 5 and Guijiao 7 were used as test materials to study the effects of different dwarfing times treatments on the agronomic and yield traits of two generations of bananas. 【Results】The results showed that the once dwarfing treatment of D82 pesticide made the plant shape of Guijiao No. 5 and Guijiao No. 7 first- generation of bananas compact, and there was no significant difference between the yield per tree and yield per unit area compared with the control,the height of cauloid was significantly reduced by 37.4 and 36.1 cm, the yield per tree was 25.9 and 27.0 kg, and the yield per mu (planting density was 145 plants/667m2) was 3.75 and 3.91 t. There was no significant difference in plant type and yield between the second-generation banana and the control, the height of cauloid was reduced by 5.0 cm and 9.8 cm, the yield per tree was 27.5 and 28.2 kg, and the yield per mu(bud density was 145 plants/667 m2) was 3.99 and 4.23 t. After two dwarf treatments, the plant shape of the first generation of Guijiao 5 and Guijiao 7 became more compact, the height of cauloid was highly significantly reduced by 62.1 and 41.4 cm, the yield per tree was 25.1 and 23.8 kg, significantly reduced by 9.39 and 13.77%, and the yield per mu (planting density was 145 plants/667m2) was 3.64 and 3.46 t, which was 9.45% and 13.5% lower than that of the control. The plant type of the second-generation banana was still tight, and the yield was not significantly different from that of the control: the height of cauloid was reduced by 20.7 and 22.3 cm compared with the control, the yield per tree was 29.1 kg and 28.2 kg, and the yield per mu (bud density was 145 plants/667 m2) was 4.22 and 4.09 t. 【Conclusion】The mid stem banana varieties Guijiao 5 and Guijiao 7 can easily achieve higher yields after dense planting treatments.Moreover,based on the comprehensive agronomic and yield traits of the two generations of bananas, dwarfing treatment significantly affects the agronomic traits and yield of the first generation. If planted in typhoon prone areas, it is recommended to only do one dwarfing treatment. |
