生物有机肥在作物品质改良和土壤修复中的研究进展

Research Progress on Bioorganic Fertilizer for Quality Improvement of Crops and Soil Remediation

生物有机肥作为功能微生物复配传统肥料形成的新兴肥料,代替化肥使用逐渐成为研究热点。面对当前土壤微生物群落遭到破坏、土壤功能严重退化的现状,本文介绍了生物有机肥的基本情况,从生物有机肥提高作物产量及品质、具有一定生物防治能力、提高植株抗逆能力和节肥效应4个方面阐述了生物有机肥对作物的影响,并从土壤理化性质、土壤微生物群落和土壤可持续利用3个方面总结了生物有机肥对土壤的修复功效。

In recent years,the extensive use of chemical fertilizers in agriculture has caused the accumulation of metal ions and salinization in the soil,which has led to the destruction of soil microbial communities and the serious degradation of soil functions,affecting the growth and quality of crops.Bioorganic fertilizer,as a new type of fertilizer formed by combining functional microorganisms with traditional fertilizers,has gradually become a research hotspot.This paper has elaborated the benefits of bioorganic fertilizer to crops,such as improving crop quality and yield,possessing a certain biocontrol capacity,enhancing crop stress resistance,and fertilizer-saving.At the same time,it has summarized the remediation effect of bioorganic fertilizer on soil from three aspects of soil physical and chemical properties,soil microbial community and soil sustainable utilization.
