Abstract:In order to further improve the yield and quality of tobacco leaves and save fertilization costs,the flue-cured tobacco variety Yunyan 87 was used as the test material.Through field experiments,four fertilization schemes were set up,including 15%(CK),20%,25%,and 30%organic nitrogen with no change in nitrogen application rate.The growth of tobacco leaves in the field and the yield and quality of cured tobacco leaves were compared and analyzed.The results showed that ensuring the same nitrogen application rate and increasing the proportion of organic nitrogen application at 25%could promote plant height increase and increase the maximum leaf area of the middle leaf,effectively optimizing agronomic traits;It could improve chromaticity,reduce greenness and gray discoloration,increase oil content,and improve the appearance quality of tobacco leaves;The aroma quality had improved,the amount of aroma has increased,the impurities and irritations had decreased,and the sensory evaluation quality of roasted tobacco leaves had been greatly improved.The proportion of high-quality tobacco had increased to 68.03%,the yield of middle and upper tobacco leaves had increased by 34.5 kg/ha,and the output value had increased by 1 649.7 yuan/ha,playing a positive role in improving economic benefits.In the tobacco planting area of Yongzhou,a fertilization ratio scheme of 25%organic nitrogen and 75%inorganic nitrogen with unchanged nitrogen application rate can be demonstrated and promoted.
