摘要:
香蕉为全球重要的经济果树，近年来因为香蕉土壤性疾病和气候因素，尤其在中国南方造成减产损失问题严重。本研究探讨新型的缓释肥料在香蕉的生长和产量表现。研究针对香蕉的营养需求制订特别配方，测试其在香蕉叶片营养、光合速率和产量上的表现。研究结果表明，在叶片的营养测时，氮、磷、钾等元素分别较传统化肥的含量高出12.5%，10%和34.8%。其光合速率比起传统化肥高出10.5%~32%。叶绿素含量方面也有所提升9.5%~10%，产量方面，较传统复合肥高出14%~20%。果实质量分析结果在可溶性固形物(%)、总糖量(%)方面无特别差异。可溶性蛋白质和可食率的表现优于传统化肥。使用此缓释肥不仅带来节约人力和施肥的成本，质量表现上亦比传统化肥有更大的优势。本试验使用第三代以沸石调控缓释效能之缓释肥料，不但可达成以上效益，其组成份沸石也是最佳的土壤改良剂，对提升土壤阳离子交换能力和肥料的利用率，和造就本研究成果有至关重要角色。值得在中国热带和亚热带区域进一步推广使用。
Banana is global important cash crop; in recent years, soil-borne diseases and climate problems have caused its serious reduction in production especially in southern China. This paper described the application of a novel slow release fertilizer and its effects on banana growth and production. The paper studied banana foliar nutrients, photosynthetic rate, chlorophyll content, and yield performance. The results indicated that foliar content of macro-elements nitrogen, phosphate, potassium in Greenfeed® group was 12.5%, 10% and 34.8%, respectively, higher than the conventional compound fertilizers. Photosynthesis rate was found 10.5% - 32% higher and chlorophyll content was measured 9.5% - 10% higher than compound fertilizer treatment. Most importantly, the yield on weight of banana was concluded to be 14% - 20% higher than conven-tional treatment. Quality analysis on the harvested banana did not display much difference on the performance on total soluble solid, total sugar, and noticeably, soluble protein and edible per-centage were found higher in Greenfeed® treatment group. This novel slow release fertilizer is la-bor- saving and cost saving; its performances on banana quality were also found better than con-ventional fertilizer. This novel fertilizer is powered by zeolite, a component with beneficial effects on soil improvement, bringing up the Cations Exchange Capacity (CEC) and utility rate of fertilizers. This novel slow release fertilizer is worth to be further promoted in tropical and subtropical region in China.
