微生物肥料的作用机理、现状及展望

The Mechanism,Current Status and Prospects of Microbial Fertilizers

微生物肥料作为一类低成本、环保的新型肥料,能有效改良土壤、提高肥力、增加作物产量,同时减少作物因病原体造成的损失,在国家农业绿色发展战略中具有重要作用。本研究从微生物肥料的分类、产品的应用、作用机理等方面,总结归纳了近年来中国微生物肥料的发展现状、菌种的分类和保藏及植物促生菌可溶性和挥发性次级代谢产物的作用机理,分析了微生物肥料行业发展面临的共性问题,最后为推动微生物肥料的发展提出了几点建议。

As a low-cost and environmentally friendly new type of fertilizer,microbial fertilizers can effectively improve soil,increase fertility,increase crop yield,and reduce crop losses caused by pathogens,playing an important role in the national agricultural green development strategy.In this paper,we summarized the development status of microbial fertilizers in China in recent years,the classification and preservation of strains,and the mechanism of soluble and volatile secondary metabolites of plant growth promoting bacteria from the aspects of classification,product application and mechanism of microbial fertilizers,and analyzed the common problems faced by the development of microbial fertilizer industry.Finally,several suggestions for promoting the development of microbial fertilizers were put forward.
