不同氮钾运筹对云烟121产质量的影响
Effects of Nitrogen and Potassium Application on Yield and Quality of Yunyan 121
摘要
Abstract
The flue-cured tobacco variety'Yunyan 121'was used as the material.Four treatments were set up,including local conventional fertilization(CK),20% reduction of nitrogen in base fertilizer + local conventional fertilization(D1),20% reduction of nitrogen in base fertilizer+20% increase of potassium in topdressing(D2),20% reduction of nitrogen in base fertilizer +20% reduction of potassium in topdressing(D3).The effects of different treatments on the growth and development of tobacco plants,soil physical and chemical properties,chemical composition,yield and quality of tobacco leaves were studied.The results showed that D2 treatment had excellent agronomic traits,better soil physical and chemical properties,more coordinated chemical composition,the best appearance quality,and the highest economic indicators.The yield was 2581.30 kg/hm2,the average price was 21.87 yuan/kg,and the output value was 56452.30 yuan/hm2.In summary,on the basis of conventional fertilization in the production of tobacco leaves in Banqiao Town,Xuanwei City,20% nitrogen reduction of base fertilizer+20% potassium increase of topdressing fertilizer is beneficial to promote the growth of tobacco plants,the coordination of chemical components of flue-cured tobacco leaves,and the improvement of yield and quality of tobacco leaves.It is recommended as a reference fertilization scheme for high-end tobacco leaves of'Hehua'brand.关键词
