Abstract

The release of nutrients from decomposing plant residues is important to obtaining adequate crop nutrition especially in agroforestry systems. Some authors have pointed out the possibility of using microbial inocula to accelerate both residue decomposition and crop growth. In order to evaluate the response of maize (Zea mays) to application of liquid microbial inoculum on Erytrhina americana residues in the soil, an experiment was conducted in semi-controlled conditions. Maize was planted in pots filled with soil treated with microbial inocula from six different locations. Indicators of maize plant response were leaf area, biomass, and seedling height; CO2 production of soil in pots was also measured. The results showed that leaf area, biomass and CO2 production responded positively to the addition of foliage of E. americana. However, only microbial nutrient inocula from two locations caused significant differences in the variables evaluated, and none was superior to the results obtained with the control, which contained soil with residue addition but without microbial inoculants. The results indicate the need for further research on dose and frequency of application and they also highlight the usefulness of the method used to find differences in the impact of different inocula.

本地微生物液体接种剂在土壤中的应用:对玉米幼苗生长的影响
从分解植物残体中释放养分对于获得充足的作物营养非常重要,特别是在农林复合系统中。一些作者指出了利用微生物接种剂加速残渣分解和作物生长的可能性。为了评价玉米(Zea mays)对土壤中美洲赤藓(Erytrhina americana)残留物施用液体微生物接种剂的反应,在半对照条件下进行了试验。玉米种植在装满土壤的花盆中,土壤经过了来自六个不同地点的微生物接种剂处理。玉米植株响应的指标为叶面积、生物量和苗高;同时测定了盆栽土壤的CO2产量。结果表明,美洲杉叶面积、生物量和CO2产量对叶片的增加有显著的响应。然而,只有两个地点的微生物养分接种对评价变量产生了显著差异,并且没有一个优于对照组的结果,后者含有添加残渣的土壤而不含微生物接种剂。研究结果表明,需要进一步研究接种剂量和频率,并强调了该方法用于发现不同接种疫苗影响差异的有效性。
