| 中文摘要: |
| 本研究以“金粉1号”粉蕉为试验材料,设置4个不同植株高度梯度处理,对其进行2次相等用量的PP333树盘淋施,通过对各处理植株新抽生叶片叶间距、植株高度、茎基围及产量性状指标的测定与比较分析,以期筛选出PP333矮化粉蕉的适宜施用时期。研究结果表明,试验用PP333处理对粉蕉产量性状无显著性影响,对粉蕉营养生长有显著抑制作用,植株叶间距明显缩短、株高降低,茎干比增加。其中T2(90 cm≤ <120 cm)处理矮化效果最为理想,收获期株高359.4 cm,较对照显著降低21.2%,茎干比较对照显著增加5.4%,果指长、果指周长、单株产量与对照相比稍有减小,差异不显著。研究结果将为粉蕉矮化栽培技术管理提供指导及必要的理论支撑。 |

| This study with "Jinfen 1" Pisang Awak as test materials,processing, four different plants were treated with height gradient, and the same amount of PP333 was applied twice. Through the determination and comparative analysis of leaf spacing of new leaves, plant height, stem base circumference and yield character indexes, In order to screen out the suitable application period of PP333.The results showed that PP333 treatment had no significant effect on yield character but vegetative growth of Pisang Awak , the leaf spacing and plant height of the plants were significantly shortened and the stem indexstem ratio increased.Among them, T2 (90 cm≤ <120 cm) treatment had the most ideal dwarf effect, plant height at harvest time was 359.4cm, which was significantly reduced by 21.2% compared with the control group, and stem index stem height was significantly increased by 5.4% , finger length, finger thickcircumference and yield per plant were slightly decreased, with no significant difference.The results will provide guidance and necessary theoretical support for the technical management of dwarfing cultivationof Pisang Awak. |
