烟草轮作与套作模式及其效应研究综述OA

The sustainable development of the tobacco industry is severely constrained by longterm continuous cropping,which is effectively addressed by crop rotation and intercropping.Therefore,the rotation and intercropping patterns of tobacco with Poaceae,Fabaceae,Brassicaceae and other crops were systematically reviewed,and their effects on soil environment,disease occurrence,tobacco leaf quality and economic benefits were analyzed.It was found that soil structure was improved,soilborne diseases were reduced,and tobacco leaf quality and comprehensive benefits were enhanced by rotation and intercropping,although problems including resource competition,poor regional adaptability,difficulty in crop rotation coordination,and market fluctuations were also observed.In the future,multiregional experimental validation should be strengthened,crop arrangement should be optimized,agricultural machinery and agronomic integration should be promoted,and the income stability of supporting crops should be ensured,so as to facilitate the green and sustainable development of tobacco cultivation systems.
