The method is easy to operate, the microenvironment of organic carbon, enzyme activity and microorganisms of rhizosphere soil of tobacco plants in the tobacco field can be improved, the multiple cropping index of the soil in the tobacco field is increased, meanwhile, soil-borne diseases caused by long-term single cropping of the flue-cured tobaccos in the tobacco field can be inhibited, and effective technical guarantee is provided for sustainable production of the flue-cured tobaccos.

The present invention belongs to the technical field of planting. Disclosed is a method for maize-flue-cured tobacco crop rotation with double intercropping of pea / barley. In the method for maize-flue-cured tobacco crop rotation with double intercropping of pea / barley of the present invention, a specific planting pattern for the crop rotation is "flue-cured tobacco-intercropped pea-intercropped barley-rotated maize-intercropped pea- rotated barley-flue-cured tobacco". The symbiotic period of the double intercropped crops in this pattern reaches 70d, and a multiple cropping index of cultivated land is increased to "six harvests in two years", leading to a substantial increase in economic benefits. Moreover, this pattern can effectively reduce the occurrence of continuous cropping obstacles in cash crops such as flue-cured tobacco and peas, and thus is a "grain-tobacco-cash crop coordinated development pattern" that enables sustainable and efficient production. The economic benefits are greatly improved. In addition, pea seedlings are applied to attract migrating tobacco aphids, which reduces aphid infestations and prevents the occurrence of climatic spot disease and tobacco brown spot in upper tobacco leaves caused by excessive nutrient absorption in the late growth stage of flue-cured tobacco.
