Abstract: Field experiments were conducted to study the effects of four different biochar application rates and conventional fertilization controls on the quality and economic benefits of flue-cured tobacco leaves in Xuanwei tobacco growing area. The results showed that the additional application of biochar can improve the physical properties, appearance quality, chemical composition coordination and sensory evaluation quality of tobacco leaves to varying degrees. Among them, T2(application rate of 900 kg/hm2) had a better effect on physical properties and appearance quality. Compared with CK (conventional fertilization), it increased by 4.64% and 2.59%, respectively. T3(application rate of 1 350 kg/hm2) had the best improvement in chemical composition coordination and sensory evaluation quality, increasing by 20.19% and 5.26%, respectively, and the overall quality was the highest, 7.62% higher than CK. T3 had the best economic benefit, and the output value reached 59 995.80 yuan per hectare, and the grade structure was the best. In summary, the best biochar application rate was 1 350 kg/hm2, the comprehensive quality of tobacco leaves was the best, and the economic benefits was the highest in Xuanwei city tobacco growing area.
