The invention belongs to the technical field of crop-rotation planting of tobacco plants and discloses a double-cropping planting method for tobacco plants and autumn peas. The method comprises the steps: tobacco plant-autumn pea crops-for-rotation link: carrying out land preparation, and carrying out basal fertilizer application; autumn pea planting: carrying out sowing, carrying out fertilizer and water management, and carrying out harvesting; autumn pea-tobacco plant crops-for-rotation link: carrying out land preparation, carrying out ridge forming, carrying out basal fertilizer application, and carrying out mulching; and tobacco plant planting: carrying out seedling raising, carrying out transplanting, carrying out field management, and carrying out mature picking and curing. Accordingto the method, the problem on tobacco field soil obstacle caused by the existing tobacco plant planting single-cropping continuous-cropping mode can be effectively solved, soil nutrients are balanced, root system development is promoted, accumulation of harmful substances and plant diseases and insect pests are reduced, the yield and quality of tobacco leaves and comprehensive economic results ofa tobacco field are improved. Shown by experiments, by the method, organic matters of soil can be increased by 10%-20%, the structure of an arable layer is improved obviously, the incidence rate of diseases is lowered by 55%, the first-class tobacco ratio of the tobacco leaves is increased by 5%-7%, the chemical ingredient coordination and sensory evaluation score of the tobacco leaves are improved obviously, and the comprehensive economic results of farmers are increased by 15%-20%.
