| 摘 要： | 为研究不同有机肥连续施用对土壤质量的影响,综述国内外不同有机肥连续施用对农田土壤理化性质、土壤微生物以及土壤重金属的影响及作用机理,并对有机肥合理利用提出建议。研究表明：连续施用有机肥能显著改善土壤结构,提高土壤的水肥调控能力,增加土壤养分的有效性,平衡土壤养分,提高土壤酸碱缓冲性能,优化土壤微生物群落的结构和功能;但长期施用有机肥会增加土壤和植物中重金属累积风险,特别是畜禽和污泥有机肥。国内外研究大部分是粪肥与污泥和化肥的配施对土壤和作物中重金属含量进行分析,对研究畜禽粪污施用年限以及有机肥长期施用下土壤中重金属的演变特征及机理探讨相对较少,今后还需加深有机肥连续施用对土壤重金属影响机理方面的研究。

| Abstract: | To study the effects of long-term application of different organic fertilizers on soil quality, the effects of continuous application of different organic fertilizers on farmland soil physical and chemical properties, soil microorganisms and soil heavy metals, as well as the mechanism of action were reviewed, and the countermeasures for rational utilization of organic fertilizers were put forward. The results showed that continuous application of organic fertilizer could significantly improve soil structure, enhance soil water and fertilizer regulation ability, increase soil nutrient availability, balance soil nutrient, promote soil acid-base buffer performance, and optimize the structure and function of soil microbial community. However, long-term application of organic fertilizers could increase the risk of accumulation of heavy metals in soil and plants, especially livestock and sludge organic fertilizers. Most of the research at home and abroad has long focused on the combined application of manure and sludge with chemical fertilizers which might influence the content of heavy metals in soil and crops, but there is still insufficient research on livestock and poultry waste application years, and the evolution characteristics and the mechanism of soil heavy metals under long-term organic fertilizer application, which could be the future study direction. |
