不同氮磷钾比例的有机无机复混肥对烤烟产质量的影响

Effects of Organic-Inorganic Compound Fertilizers With Different Ratios of Nitrogen,Phosphorus And Potassium on The Yield And Quality of Flue-Cured Tobacco

为探索皖南地区烤烟土壤条件下适宜的有机无机复混肥配方,以常规施肥为对照,研究了不同氮磷钾比例的有机无机复混肥对烤烟产质量的影响。结果表明:施用有机无机复混肥的处理较CK处理烟叶产量增加168~312kg/hm^(2),产值较CK处理增加4027.2~7747.2元/hm^(2);烟叶质量有明显提升,施用有机无机复混肥的烟叶质量较为稳定;皖南烟区适宜的N∶P_(2)O_(5)∶K_(2)O应为5∶6~8∶14。

In order to explore the suitable organic-inorganic compound fertilizer formula under the soil conditions of flue-cured tobacco in southern Anhui,with conventional fertilization as a control,the effects of organic-inorganic compound fertilizer with different ratios of nitrogen,phosphorus and potassium on the yield and quality of flue-cured tobacco were studied.The results showed that the treatment with organic-inorganic compound fertilizer increased the tobacco yield by 168-312kg/hm^(2) compared with the CK treatment,and the output value increased by 4027.2-7747.2 yuan/hm^(2) compared with the CK treatment,and the quality of tobacco leaves was significantly improved.The quality of tobacco leaves using organic-inorganic compound fertilizers is relatively stable.It is recommended that the appro⁃priate N:P_(2)O_(5):K_(2)O in southern Anhui tobacco areas should be 5:6-8:14.
