| 本试验以巴西蕉为材料，研究香蕉配方肥在海南玄武岩砖红壤上应用效果，以期探索出促进香蕉生长的配方肥配方及施肥方案。结果表明：与常规施肥相比，配方肥的施用提高了香蕉株高和茎粗，增加了香蕉产量，每公顷增产20.9%，每梳果指数、果长、单果重、果实Vc含量、糖度、可溶性蛋白、糖酸比等都有所提高；配方肥施用处理中，香蕉N、P、K的利用率分别提高了17.37%、13.90%和3.65%，肥料贡献率提高了14.48%，肥料农学利用率提高了8.69kg/kg；每公顷的施肥成本节省了2352.75元，纯收入增加了36.60%。 |
| 英文摘要: |
| In this study, we take banana seedlings (Musa AAA Cavendish cv. Brazil) as the test material to investigate the effects of application banana formula fertilizer on the banana growth in the basalt laterite. In hence to explore the suitable formulation and the efficiently applying plan of the banana formula fertilizer to promote the banana growth. The results showed that compared with conventional fertilizer, formula fertilizer increased the plant height and stem diameter as well as the yield of banana. After application of the formula fertilizer, the yield was increased by 20.9% per hectare. In addition, the number of the bananas per bunch, fruit length, the mean banana fruit yield, the content of vitamin c, soluble protein and sugar, the ratio of sugar/acid were all increased. Application of formula fertilizer could also improve the fertilizer utilization efficiency including N, P, K, fertilizer contribution and agriculture fertilizer utilization by 17.37%, 13.90%, 3.65%, 14.48% and 8.69kg/kg, respectively. For economic benefit, application of formula fertilizer saved the cost of 2352.75 Yuan per hectare, and the profit rate was increased by 36.60% per hectare. |
