中文摘要:
      盐碱地是我国重要的后备耕地资源,盐碱地治理与农业利用在保障口粮绝对安全、保持现有耕地稳定、坚守粮食基本自给的安全底线等方面具有重要作用。环境友好型土壤改良剂—生物炭在促进农业可持续发展方面前景巨大。然而,现有研究多关注于生物炭在中性和酸性土壤中的改良作用,缺乏其对盐碱地改良的深入研究和系统总结。通过综合分析国内外生物炭在盐碱土壤物理性质、化学性质、养分利用和微生物方面的研究进展,总结了生物炭在盐碱地改良中的可能机制,并对生物炭在盐碱地的应用前景进行了展望,以期为盐碱地生态治理提供参考。
英文摘要:
      Saline-alkaline soil is an important reserve resource of arable land in our country. Saline-alkaline soil management and agricultural utilization play an important role in ensuring the absolute safety of rations, maintaining the stability of existing arable land, and adhering to the safety bottom line of basic food self-sufficiency. Biochar, which is an environmentally friendly soil amendment, has a great prospect in promoting the sustainable development of agriculture. However, most of the existing researches focused on the improvement effect of biochar in neutral and acidic soil, and lacked of in-depth research and systematic summary on the improvement effect of biochar in saline-alkaline soil. This article comprehensively analyzed the research progress of biochar in physical properties, chemical properties, nutrient utilization and microorganisms in saline-alkaline soil, summarized the possible mechanism of biochar in saline-alkaline soil amelioration. The application prospect of biochar was prospected in order to provide reference for ecological management of saline-alkaline soil.
