轮作改善土壤健康与缓解连作障碍的研究进展OA

The long-term monoculture intensive farming model has led to continuous cropping obstacles,resulting in soil acidification and fertility decline,which have become significant challenges hindering the sustainable development of agriculture.Crop rotation system,as an important agricultural management measure,can effectively improve soil structure,reduce the accumulation of self-toxic substances,and break the cycle of pathogens,thereby alleviating the negative impacts of continuous cropping obstacles.This paper summarises the primary causes of continuous cropping obstacles and explores the mechanisms through which crop rotation system mitigate these obstacles from various perspectives,including soil properties,nutrient composition,enzyme activity,allelochemicals,crop yield,and quality.Additionally,it provides insights into the current challenges faced by crop rotation system in practical production and their future prospects,aiming to offer references for further research on crop rotation system.
