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%.
