被孢霉在可持续农业生产中的应用研究进展

Research progress on the application of Mortierella in sustainable agricultural production

被孢霉是典型的土壤腐生真菌,广泛存在于土壤及植物体内。近期大量研究结果表明,土壤中的被孢霉具有促进植物生长和帮助植物抑制病害的潜力。本文基于被孢霉的分类地位及共性特征,分别从被孢霉降解农业废弃物和有机污染物修复土壤,溶磷、产铁载体促进土壤营养元素转化,分泌植物激素和脂肪酸类物质促进植物生长,分泌拮抗物质调控根际微生物种群丰度,诱导植物自身防御反应提高植物抗病性等方面总结了被孢霉的研究与应用进展。并且对今后被孢霉在可持续农业生产中的应用前景进行了展望,以期为研制安全、稳定、高效的农业生产中微生物菌剂提供方向,为优化植物促生及抑病策略奠定基础。

Mortierella is a typical saprophytic fungus in soil and plants.Recent studies have shown that Mortierella in soil has the potential to promote plant growth and help plant control disease.Based on the taxonomic status and common characteristics of Mortierella,this article summarized the research and application progress of Mortierella in the degradation of agricultural waste and organic pollutants to remediate soil,promoting the transformation of soil nutrients through phosphorus and iron production carriers,secreting plant hormones and fatty acid substances to promote plant growth,secreting antagonistic substances to regulate the abundance of rhizosphere microbial populations,inducing plant defense reactions to improve plant disease resistance.And the future application prospects of Mortierella in sustainable agricultural production were discussed to provide direction for the development of safe,stable,and efficient microbial agents for agricultural production,and to lay a foundation for optimizing plant growth promotion and disease inhibition strategies.
