为了解多效唑在粉蕉生产中的使用效果和安全性,对粉蕉进行土壤淋施和整株喷施不同剂量多效唑的对比研究。结果表明:在春植粉蕉植株假茎高度1.0 m时开始进行多效唑矮化处理(若施2次,间隔30 d),末次施药距采收安全间隔9个月以上,单株施用剂量累计不超过5.0 g,不会导致多效唑在蕉果及土壤中的残留,可起到改善蕉果品质的作用,使果实可溶性糖及可溶性固形物含量增加;随使用剂量增加,矮化效果越明显,且土壤淋施比整株喷施效果好。
In order to understand the effect and safety of paclobutrazol used in the production of banana plantain, comparative study was conducted on soil leaching and whole plant spraying with different doses of paclobutrazol. The results showed that when the height of pseudostem of spring plantain was 1.0 m, the dwarfing effect of moxifloxacin (if two times and interval of 30 days), the safety interval of harvesting for the last time was more than 9 months, Not more than 5.0 g, it will not cause the residual of paclobutrazol in banana and soil, which can improve the quality of banana fruit, and increase the content of soluble sugar and soluble solid. With the increase of dosage, the dwarfing effect is more obvious, Soil leaching and spraying better than the whole plant.
