生物措施缓解酸性土壤铝毒害研究进展

Advancements in the Study on Biological Means Mitigating Aluminum Toxicity in Acid Soils

酸性土壤在世界上广泛存在,Al毒是酸性土壤限制作物生长和产量的主要限制因子之一。本文概述了酸性土壤Al毒害问题以及作物的耐Al机制,总结了遗传改良植物的耐Al性、向土壤或植物根际接种外生菌根真菌和其他耐Al微生物以缓解酸性土壤Al毒害的研究进展。以上措施在酸性土壤中的生态系统恢复具有应用前景。

Acid soils extensively exist on the globe and aluminum toxicity is one of the main factors limiting crop growth therein. A review was presented to address aluminum toxicity to plants and mechanism of aluminum tolerance of plants, and summarized advancements in the study on biological means mitigating aluminum toxicity to plants in acid soils, such as genetic rebuilding of plants tolerance to aluminum toxicity, and inoculating of exotrophic mycorrhizal fungi or other aluminum-tolerant microorganisms into the soil or plants. The above-mentioned biological means will have bright prospects in application to remedying eco-environment of acid soils.
