摘　　要：为探讨随滴灌水施用敌革胺对不同品种烟草经济性状和农艺性状的影响，选用五个品种烟草：豫烟5号、豫烟7号、中烟100、NC89、KRK28，随滴灌水施用敌草胺除草剂，敌草胺施用量分别为：Okg／hm^2、1．50kg／hm^2、2．25kg／hm^2、3．00kg／hm^2、3．75kg／hm^2。结果表明，不同品种烟草随滴灌水施用敌草胺的处理经济性状烟叶产量和上等烟产量均较对照有所增加，但随着敌草胺施用量的增加，烟叶产量增加的幅度变小，当敌草胺施用量大于3．00kg／hm^2时，烟叶产量增加缓慢。随滴灌水施用敌草胺对不同烟草品种农艺性状的影响不尽相同，但同一烟草品种随滴灌水施用敌草胺的处理与对照比，株高、有效叶片数、叶面积系数均有不同程度增加，大多数差异达到了显著或极显著水平。生产中豫中地区选用表现较好的豫烟5号和KRK28两个烟草品种，随滴灌水施用敌草胺以2．25～3．00kg／hm^2为宜。To explore the effect of Napropamide herbicide application with the drip irrigation water on economic and agronomic characters of different tobacco varieties, five different tobacco varieties were selected as Yuyan 5, Yuyan 7, Zhongyan 100, NC89 and KRK28, and application amounts of napropamide with the drip irrigation water were 0 kg/hm^2,1.50 kg/hm^2, 2.25 kg/hm^2, 3.00 kg/hm^2, 3.75 kg/hm^2 respectively. Results showed that the tobacco leaf production and first-class leaf production of different tobacco varieties applied by napropamide herbicide with drip irrigation water were all increased more than control, but the increased ranges of them were shrunk with the increase of Napropamide applied amounts, and when Napropamide applied amount was greater than 3.00 kg/hm^2, the tobacco leaf production increased slowly. And its effect on the agronomic characters of different tobacco varieties were different, but comparing to control the plant height, effective leaf number, leaf area index of the same tobacco variety were inordinately increased with the application amounts of napropamide herbicide with the drip irrigation water, and the most of them reached significant or extremely significant level. Therefore, the tobacco varieties were recommended to choose as Yuyan 5 and KRK28, the application contents of Napropamide herbicide with the drip irrigation water were recommended to choose as 2.25 - 3.00 kg/hm^2 in the tobacco fields in central district of Henan province.
