摘　　要：以云烟121为供试材料,设置常规施肥(CK)、基肥减氮20%+当地常规施肥(D_(1))、基肥减氮20%+追肥增钾20%(D_(2))、基肥减氮20%+追肥减钾20%(D_(3))等4个处理,研究不同处理对烟株生长发育、土壤理化性质、烟叶化学成分及烟叶产量和质量的影响。结果表明:D_(2)处理的烤烟农艺性状优良、土壤理化性质更优、化学成分更协调、外观质量最好,各项经济指标最高,产量达2581.30 kg/hm^(2),均价达21.87元/kg,产值达56452.30元/hm^(2)。综上所述,在宣威市板桥镇烟叶生产常规施肥的基础上基肥减氮20%+追肥增钾20%有利于促进烟株生长,增加烤后烟叶化学成分协调性,提高烟叶产量和品质,推荐作为“荷花”品牌高端烟叶原料的参考施肥方案。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(D_(1)),20%reduction of nitrogen in base fertilizer+20%increase of potassium in topdressing(D_(2)),20%reduction of nitrogen in base fertilizer+20%reduction of potassium in topdressing(D_(3)).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 D_(2) 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/hm^(2),the average price was 21.87 yuan/kg,and the output value was 56452.30 yuan/hm^(2).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.
