Abstract:

In order to improve the quality of tobacco leaves, increase the income of tobacco farmers, and improve the enthusiasm of tobacco farmers, the rotation and intercropping mode of tobacco in Xuchang tobacco area was studied. The demonstration results showed that T3 treatment increased the contents of soil organic matter, total nitrogen, alkali hydrolyzable nitrogen, available phosphorus and available potassium before tobacco transplanting. Compared with T4 treatment, the plant height, stem circumference, pitch, leaf number, maximum leaf length and maximum leaf width of tobacco plants were increased by 13.86%, 35.04%, 8.54%, 13.31%, 6.64% and 13.86%, respectively. The incidence of tobacco mosaic disease was the lowest in T2 treatment at different growth stages of flue-cured tobacco, while the incidence of tobacco black shank disease was the lowest in T3 treatment at different growth stages of flue-cured tobacco. The 667 m2 benefits of T1 treatment was the highest, which was 7 328.00 yuan, which was 36.10%, 59.44% and 15.32% higher than that of T2, T3 and T4 treatments, respectively. Flue-cured tobacco of T1 treatment had the highest overall score of appearance quality. The nicotine content of T1 and T3 treatments was more appropriate, and the conventional chemical composition of tobacco leaves was more harmonious. The sensory quality of tobacco leaves in T1 treatment was the best. In general, T1 treatment is the best in Xuchang tobacco area.
