Evaluation of the potential mechanisms that link arbuscular mycorrhizal fungi (AMF) and green algae to carbon mineralization is highly fundamental under saline arid land since a deep vision into these interrelationships might lead to improvements in soil quality, carbon protection and the implication for a better ecosystem functioning. This study aimed to determine the interactions between arbuscular mycorrhizal fungi (Glomus mosseae), algal biomass (chlamydomonas sp) and subsequent effects on carbon mineralization, bacterial biomass carbon, soil pH, roots density, large macroaggregates (>2000 μm), small macroaggregates (250–2000 μm) and microaggregates (53–250 μm) in maize crop. The general nature of the results that were significant and what they mean is sufficient. Overall, results showed that the combination of AM fungi with algae was effective and provoked carbon decomposition and soil aggregates formation by lowering pH and boosting bacterial biomass C as well as roots density which can be beneficial to soil ecology through the enhancement of the soil bio-characteristics and the potential for the corn growth promotion in the arid saline soil.

干旱盐渍土上施用丛枝菌根真菌和绿藻后土壤碳矿化,土壤微生物,根系密度和土壤结构的变化

在盐碱干旱地区,评估将丛枝菌根真菌(AMF)和绿藻与碳矿化联系起来的潜在机制非常重要,因为对这些相互关系的深入了解可能会导致土壤质量改善,碳保护以及对改善生态系统的影响运作。这项研究旨在确定丛枝菌根真菌(Glomus mosseae)与藻类生物量(chlamydomonas sp)之间的相互作用。)以及随后对玉米作物中碳矿化,细菌生物量碳,土壤pH值,根系密度,大的大骨料(> 2000μm),小的大骨料(250-2000μm)和微骨料(53-250μm)的影响。有意义的结果的一般性质及其含义就足够了。总体而言,结果表明,AM真菌与藻类的结合是有效的,并通过降低pH值,增加细菌生物量碳和根系密度,促进了碳的分解和土壤团聚体的形成,可通过增强土壤生物量而有益于土壤生态。干旱土壤中玉米的生长特性和促进玉米生长的潜力。
