This study reports the vermicomposting of banana crop waste biomass by Eisenia fetida. Cow dung has been used as bulking agent in this study. The experiment was conducted in six vermireactors containing different ratios of banana leaf waste biomass (BL) and cow dung (CD) for 105 days. Earthworm activity significantly reduced pH, TOC, C:N and C:P ratio of the wastes. Whereas macronutrients and micronutrients content increased after vermicomposting. TOC content of wastes reduced by 40-64% and C:N ratio of the vermicomposts was in the range of 8.9-24.3. The benefit ratio for heavy metals (Cu, Fe, Zn, Cd, Pb, Mn and Cr) was in the range of 0.23-3.44. The results indicated that the growth and fecundity of the earthworms was best in the vermireactors having 20-40% BL. Finally, it was concluded that vermicomposting can be included in the overall scheme of banana crop waste management.
本研究报告了利用赤子爱胜蚓对香蕉作物废弃物生物质进行堆肥。本研究中使用牛粪作为膨胀剂。该实验在六个含有不同比例香蕉叶废物生物质（BL）和牛粪（CD）的蚯蚓反应器中进行了 105 天。蚯蚓活动显著降低了废物的 pH 值、TOC、C:N 和 C:P 比。而堆肥后大量和微量营养素的含量增加。废物的 TOC 含量减少了 40-64%，堆肥的 C:N 比在 8.9-24.3 之间。重金属（Cu、Fe、Zn、Cd、Pb、Mn 和 Cr）的效益比在 0.23-3.44 之间。结果表明，在 BL 含量为 20-40%的蚯蚓反应器中，蚯蚓的生长和繁殖能力最佳。最后得出结论，蚯蚓堆肥可以纳入香蕉作物废弃物管理的总体方案中。
