Effect of Organic Material Improvement on the Growth,Development,and Yield and Quality of Flue-cured Tobacco in Shangluo Tobacco Region
Using different improved organic materials as materials,the effects of different improved organic materials on the growth,develop-ment,and quality of Shangluo flue-cured tobacco were studied,in order to provide a theoretical basis for reducing the cost of organic fertilizer use in Shangluo tobacco area.In 2022,a community experiment on improving soil with organic materials was conducted in Luonan County,Shangluo City,Shaanxi Province.Three treatments were set up:T1(conventional fertilization+high carbon base fertilizer 750 kg/hm2),T2(con-ventional fertilization+commercial chicken manure 750 kg/hm2),and T3(conventional fertilization+decomposed cake fertilizer 750 kg/hm2).CK0(conventional fertilization,no organic fertilizer)and CK1(conventional fertilization+tobacco company set organic fertilizer)were used as controls.The results showed that different improved organic materials could significantly improve the agronomic traits and disease resistance of tobacco plants;different improved organic materials increased the material accumulation of tobacco plants and enriched their organic elements;Different improved organic materials significantly improved the economic traits of flue-cured tobacco.The use of different improved organic ma-terials in soil was beneficial for improving the yield and quality of Shangluo flue-cured tobacco,among which T1(conventional fertilization+high carbon base fertilizer 750 kg/hm2)and T2 treatment(conventional fertilization+commercial chicken manure 750 kg/hm2)had the best effect on improving the growth and development of Shangluo flue-cured tobacco.
