Abstract The freeze-thaw phenomenon is one of the factors, which has an important role in increasing the qualitative and quantitative loss of soil. However, the dynamics and mechanism of freeze-thaw processes remain unknown. Therefore, adoption of appropriate conservation measures in the highland and mountains region and reduction of the effects of a freeze-thaw cycle on soil loss through application of environmentally friendly and feasible techniques of application of soil microenterprises is critical. Bacteria and cyanobacteria play an important role in the ecosystem function by improving soil physical and chemical properties. Nonetheless, the effectiveness of such microorganism on controlling soil loss has not been studied yet. The present study was accordingly designed to inhibit soil loss through inoculation of soil microorganisms including bacteria and cyanobacteria at 0.25 m2-plots under the freeze-thaw process and simulation of rainfall of 70 mmh−1 nested at the slope of 20%. To this end, the most suitable bacteria and cyanobacteria effective in soil and water conservation and available in the soil organism's micro-bank were selected, purified, and propagated as a biological method to alleviate freeze-thaw cycle effects. The experimental treatments were prepared in the form of bacterial additions, cyanobacterial additions, and control at the plot scales. After 60 days under freeze-thaw cycles, the results of statistical analyses confirmed significant inhibition (P

通过接种地方性土壤微生物减少由冻融循环引起的土壤流失

摘要 冻融现象是增加土壤定性和定量损失的重要因素之一。然而，冻融过程的动力学和机制仍然未知。因此，在高原和山区采取适当的保护措施，通过应用环境友好、可行的土壤微型企业应用技术来减少冻融循环对土壤流失的影响至关重要。细菌和蓝藻通过改善土壤理化性质，在生态系统功能中发挥重要作用。尽管如此，尚未研究此类微生物在控制土壤流失方面的有效性。因此，本研究旨在通过在 0.25 平方米的地块上在 0.25 平方米的地块上接种细菌和蓝藻等土壤微生物来抑制土壤流失，该地块在冻融过程和 70 mmh-1 降雨的模拟下嵌套在 20% 的斜坡上。为此，选择、纯化和繁殖对水土保持有效且在土壤生物微库中可用的最合适的细菌和蓝藻，作为减轻冻融循环效应的生物学方法。实验处理以添加细菌、添加蓝藻和在小区尺度上控制的形式制备。在冻融循环下 60 天后，统计分析结果证实显着抑制（P 冻融过程下的 25 平方米地块和 70 mmh-1 降雨量的模拟嵌套在 20% 的坡度处。为此，选择、纯化和繁殖对水土保持有效且在土壤生物微库中可用的最合适的细菌和蓝藻，作为减轻冻融循环效应的生物学方法。实验处理以添加细菌、添加蓝藻和在小区尺度上控制的形式制备。在冻融循环下 60 天后，统计分析结果证实显着抑制（P 冻融过程下的 25 平方米地块和 70 mmh-1 降雨量的模拟嵌套在 20% 的坡度处。为此，选择、纯化和繁殖对水土保持有效且在土壤生物微库中可用的最合适的细菌和蓝藻，作为减轻冻融循环效应的生物学方法。实验处理以添加细菌、添加蓝藻和在小区尺度上控制的形式制备。在冻融循环下 60 天后，统计分析结果证实显着抑制（P 并作为一种生物方法传播以减轻冻融循环效应。实验处理以添加细菌、添加蓝藻和在小区尺度上控制的形式制备。在冻融循环下 60 天后，统计分析结果证实显着抑制（P 并作为一种生物方法传播以减轻冻融循环效应。实验处理以添加细菌、添加蓝藻和在小区尺度上控制的形式制备。在冻融循环下 60 天后，统计分析结果证实显着抑制（P
