土壤盐碱化是一个全球性问题,我国盐碱化土壤面积较大,严重影响当前农业发展,因此提高植物抗盐碱胁迫能力,盐碱土壤改良已成为当前我国生物科学面临的重大课题之一。菌根真菌是生态系统中普遍存在的土壤微生物,它在增强寄主植物的抗盐碱胁迫能力中的作用逐渐引起国内外学者的广泛关注。笔者从盐碱胁迫下菌根真菌对植物生长、营养吸收的影响,和菌根真菌提高植物抗盐碱胁迫能力的机理两方面,对近年来国内外有关研究成果进行了综述。同时也对当前研究中存在的问题以及今后的研究方向进行了探讨。
Salinization of soil is a global problem. Because of the large area of salinized soil in our country, it has a serious impact on the current agricultural development. Therefore, improving the capacity of plant to resist saline-alkali stress and improving soil-saline-alkali soil has become one of the major topics in biological science in our country . Mycorrhizal fungi are ubiquitous soil microorganisms in ecosystems and their role in enhancing the ability of host plants to resist salt-alkali stress gradually aroused widespread concern of scholars at home and abroad. In this paper, the author summarizes the research results at home and abroad from the aspects of the effects of mycorrhizal fungi on plant growth and nutrient absorption under saline-alkali stress and the mechanism of mycorrhizal fungi in enhancing their ability to resist saline-alkali stress. At the same time, the existing problems in the current research and the future research directions are also discussed.
