| 摘 要： | 目的]探讨不同种类叶面肥对香蕉品质和产量的影响,为香蕉优质高产栽培提供参考依据.方法]于香蕉果指反梳期对其果指喷施氨基酸、海藻酸和微量元素类叶面肥,跟踪分析各处理香蕉果皮色差、果实特征、果实养分含量和产量等指标.结果]香蕉果指喷施氨基酸和海藻酸类叶面肥后果皮亮度显著提高(P<0.05,下同),果指长度分别为22.03和21.01 cm,显著高于对照(喷施清水,CK)13.50%和8.24%;喷施微量元素和氨基酸类叶面肥香蕉果实的氮、钾养分含量分别为4.04和2.87 g/株及4.51和2.78 g/株,显著高于CK,产量分别为19.39和21.74 kg/株,显著高于CK.结论]在香蕉反梳期对其果指喷施氨基酸和海藻酸类叶面肥可显著提高香蕉果皮的亮度,喷施氨基酸和微量元素类叶面肥可显著提高香蕉果实氮钾含量和产量.因此,香蕉生产中可有目的地选择使用不同类型的叶面肥.

| Abstract: | Objective]In this paper,the effects of spraying different foliar fertilizers on yield and quality of banana were investigated so as to provide reference for selecting quality and high-yield planting of banana.Method]Amino acids, alginic acid and microelement foliar fertilizers were sprayed during banana backcomb period,the indexes including peel color difference,fruit characteristics,nutrient content and yield were dynamically traced.Result]Banana peel brightness enhanced significantly(P<0.05,the same below)after spraying amino acid and alginic acid foliar fertilizers,and their fruit finger lengths were 22.03 and 21.01 cm respectively,which were significantly higher(13.50% and 8.24% respectively) than that of control(spraying clear water,CK).After spraying amino acid foliar fertilizers,nitrogen accumulation(4.04 g/plant)and potassium accumulation(2.87 g/plant)were significantly higher than those of CK,and its yield was 19.39 kg/plant,which was also significantly higher than that of CK.After spraying microelement foliar fertilizers,nitrogen accu-mulation(4.51 g/plant)and potassium accumulation(2.78 g/plant)were significantly higher than those of CK,and its yield was 21.74 kg/plant,which was also significantly higher than that of CK.Conclusion]Spraying amino acid and al-ginic acid foliar fertilizers on fruit fingers can significantly improve banana peel brightness during banana backcomb period. And spraying amino acid and microelement foliar fertilizers can significantly improve banana yield and nitrogen and potas-siun accumulation.Therefore,various foliar fertilizers shoule be selected according to the specific goals. |
