| 为了研究缓释肥料棒对香蕉的生长、产量和品质的影响,为缓释肥料棒在香蕉上的应用提供理论基础,本试验设置了常规施肥(CT)、缓释肥料棒(F1)、缓释肥料棒减施20%(F2)和不施肥处理(CK)4个处理,分析了各处理对香蕉株高、茎围、叶片数、养分积累量、产量与品质的影响。结果表明：F1处理的总叶片数较CT处理显著提升6.55%,氮素积累量较CT处理提高了2.36%； F2处理磷、钾的积累量较CT处理显著提高了14.13%,24.40%。与CT处理相比,缓释肥料棒处理能显著增加单株产量16.9%~17.63%,香蕉可食率较CT处理显著提高了6.46%~10.06%,但对香蕉可溶性固形物、可滴定酸和Vc含量无显著影响。因此,综合考虑香蕉生长发育、养分积累、产量、品质以及施肥次数,缓释肥料棒减施20%为供试条件下最优施肥处理。 |

| In order to study the effects of slow release fertilizer stick on the growth, yield and quality of bananas and provide a theoretical basis for the application of slow release fertilizer stick on bananas, four treatments were set up in this experiment: conventional fertilization (CT), slow release fertilizer stick (F1), 20% reduction of slow release fertilizer stick (F2) and no fertilization treatment (CK). The effects of each treatment on banana plant height, stem circumference, leaf number, nutrient accumulation, yield and quality were analyzed. The results showed that the total leaf number of F1 treatment was significantly increased by 6.55% compared with CT treatment, and the nitrogen accumulation was increased by 2.36% compared with CT treatment; The accumulation of phosphorus and potassium in F2 treatment was 14.13% and 24.40% higher than that in CT treatment. Compared with CT treatment, slow release fertilizer stick treatment can significantly increase the yield per plant by 16.9%~17.63%, and the edible rate of banana is significantly increased by 6.46%~10.06% compared with CT treatment, but it has no significant effect on the content of soluble solids, titratable acid and Vc of banana. Therefore, considering banana growth and development, nutrient accumulation, yield, quality and fertilization times, 20% reduction of slow release fertilizer rod was the best fertilization treatment under the test conditions. |
