本研究的目的是比较家禽粪便（PM）和香蕉废物（BW）作为固氮菌属、固氮菌属和磷增溶菌菌株组成的细菌联合体的接种载体的有效性，并确定香蕉种植土壤中生物肥料的最有效剂量（Musa paradisiaca AAA Simmonds），关于改善植物性能和土壤物理和微生物学性质。种植后6个月，植物生长随着施用的生物肥料剂量的增加而增加。BW上制备的生物肥料比PM上制备的生物肥料在更大程度上提高了解磷细菌的密度、有效磷和叶面磷的浓度。在PM上制备的生物肥料对土壤团聚体稳定性、酶活性和活性碳组分的增加与施用剂量高度相关。这两种生物肥料都可以被认为是潜在的PGPR接种载体，但BW的用途似乎仅限于中等剂量的应用（
The aims of our study were to compare the effectiveness of poultry manure (PM) and banana waste (BW), with regard to their use as inoculant carriers of a bacterial consortium constituted by strains of Azospirillum, Azotobacter and P-solubiliser bacteria and to establish the most efficient dose of biofertilizer for a soil cultivated with banana (Musa paradisiaca AAA Simmonds), with respect to improving plant performance and soil physical and microbiological properties. Six months after planting, plant growth had increased with increase in dose of the biofertilizers applied. The biofertilizer prepared on BW enhanced the density of P-solubiliser bacteria, the concentrations of available P and foliar P to a greater extent than with the biofertilizer prepared on PM. The increases produced by the biofertilizer prepared on PM for the soil aggregate stability, enzymatic activities and the labile carbon fractions were highly correlated to the dose applied. Both biofertilizers can be considered potentially useful as inoculant carriers of PGPR but the usefulness of BW appears to be restricted to moderate doses of application (
