摘　　要：为陇县特色优质烟叶生产提供依据，以秦烟96为对象，在当地进行了灌水、氮肥及其互作对烤烟现蕾期生长及经济性状的影响试验。结果表明：灌水、氮肥及其互作均对烤烟叶面积、光合特性及经济性状产生显著影响，对烤烟叶面积影响程度大于对其他农艺性状的影响。相同施氮量下，灌水组烤烟农艺性状、光合作用及经济性状显著好于未灌水组。随施氮量的增加，未灌水条件下，烤烟农艺性状、光合作用及经济性状呈上升趋势；灌水条件下，则均先升高后降低。处理A，B，（适时灌溉，确保伸根期、旺长期和成熟期烟田土壤相对含水量达到55％～65％、75％～80％和65％～70％；氮肥45kg／h㎡）的综合效果最好，其产量达2841．7kg／h㎡，产值为44881．8元／h㎡，上等烟比率23．6％，中等烟比率56．3％，均显著高于其他处理。In order to provide a reference for characteristic high-quality tobacco production in Longxian County, an experiment was conducted to study the effects of irrigation, nitrogen fertilizer and their interactions on growth and economic traits of flue-cured tobacco Qinyan 96 in squaring stage. The results showed that irrigation, nitrogen fertilizer and their interactions had significant influence on leaf area, photosynthetic characters and economic traits of flue-cured tobacco. The effects of them on leaf area was better than other agronomic traits. Agronomic traits, photosynthesis and economic traits of flue-cured tobacco in irrigation were significantly better than that from no- irrigation under the same N application rate. In addition, with increasing N application rate, agronomic traits, photosynthesis and economic characters of flue-cured tobacco showed an increasing trend under no-irrigation conditions, while ascend first and then descend in irrigation conditions. The effect of AIB1 （irrigation in good time,suitable relative water of soil tobacco field for the rooting stage, strengtrly growing stage and mature stage was 55o//oo 65%,75%80%,65%70%,respectively. nitrogen fertilizer 45 kg/h㎡） was the best,yield2 841.7 kg/ hmZ,output value 44 881. 8 Yuan/hmz, percentage of superior tobacco 23. 6%, percentage of medium tobacco 56.3% ,and these parameters were significantly higher than that of other treatments.
