Soil salinity is one of the essential factors of soil degradation and erosion in arid and semiarid regions, seriously limiting sustainable development. New technologies in controlling and restoring saline soils have to support the United Nations Sustainable Development Goals. In the same vein, despite the approved role of biological amendments in controlling soil and water loss, the inoculation of soil cyanobacteria to reduce soil degradation in saline soils has yet to be considered. For this purpose, the studied soil was collected from the Incheboron Area in Northeast Golestan Province, Iran, due to saline and sodium soil being sensitive to water erosion and unstable ecological conditions. The experiments were set up in 0.5 × 0.5-m small erosion plots with soil having different salinities and slopes in the Rain and Erosion Simulation Laboratory of Tarbiat Modares University, Iran. The treated plots with endemic cyanobacteria and untreated (control) plots were compared after eight weeks under simulated rain conditions with an intensity of about 70 mm h−1 lasting for 30 min. The results of the research showed that the runoff volume resulted from the simulated rainfall in the plots with low salinity and 10 % slope and high salinity and 5 % slope inoculated by cyanobacteria were 54.60 and 83.32 % less than untreated plots, respectively. Soil loss was also significantly inhibited (p < 0.001) by seven and 16 times compared to the control treatment. In other words, the treatment of cyanobacteria inoculation on soil with high salinity and low slope was about eight times more effective than that of soil with low salinity and higher slope. Therefore, soil cyanobacteria inoculation can be considered an adequate soil and water conservation strategy in the saline region.

通过蓝藻作用抑制盐渍土壤中的土壤和水分流失
土壤盐分是干旱半干旱地区土壤退化和侵蚀的重要因素之一,严重制约了可持续发展。控制和恢复盐渍土壤的新技术必须支持联合国可持续发展目标。同样,尽管生物改良剂在控制土壤和水流失方面的作用已得到认可,但尚未考虑接种土壤蓝藻以减少盐渍土壤中的土壤退化。为此,由于盐碱和钠土壤对水侵蚀和不稳定的生态条件敏感,从伊朗东北部 Golestan 省的 Incheboron 地区收集了研究的土壤。在伊朗 Tarbiat Modares 大学雨水侵蚀模拟实验室,在 0.5 × 0.5 m 的小侵蚀地块中,土壤具有不同的盐度和坡度。八周后,在强度约为 70 mm h-1 持续 30 分钟的模拟降雨条件下,比较具有地方性蓝藻处理的样板和未处理(对照)样板。研究结果表明,在低盐度和 10 % 坡度以及高盐度和 5 % 坡度接种的样地中,模拟降雨产生的径流量分别比未处理的样地少 54.60 和 83.32 %。与对照处理相比,土壤流失也显著抑制了 7 倍和 16 倍 (p < 0.001)。换言之,在高盐度、低坡度的土壤上接种蓝藻的效果是低盐度、高坡度土壤的 8 倍左右。因此,土壤蓝藻接种可以被认为是盐碱区的适当水土保持策略。
