灌水量和施氮量对香料烟生长和经济效益的影响

采用大田试验研究了旺长期的不同灌水量和不同施氮量对‘云香巴斯玛一号’香料烟生长和经济效益的影响。结果表明，旺长期灌水量是影响香料烟生长和经济效益的重要因素，随着旺长期灌水的增量，地上部生长势、株高、叶片数和叶片大小均增加，叶片干物质积累量明显，产量和产值呈显著增加；随着施氮量的增加，茎和根的干物质积累量呈上升趋势。总体分析，在高灌水量条件下施氮量75 kg/hm2时，有利于‘云香巴斯玛一号’香料烟的生长发育，获得较高产量和产值。

Effect of Irrigation and Nitrogen Application Rate on Growth and Economic Benefits of Aromatic Tobacco

The field experiment studied the effect for aromatic tobacco ’ Yunnam Tobacco Basima 1 ’ （YNOTBS1）,on growth potential and economic benefit through different treatment of irrigation and nitrogen application.The result showed that the irrigation consumption at rapid growing period of aromatic tobacco was a most important fact which could influence the growth and income.Not only the growing potential above ground part,height of plant,amount and size of leaves were increased,but also the dry matter accumulation of leaves,yield and value were significantly increased,as the increase of irrigation at rapid growing period on aromatic tobacco;the dry matter of accumulation quantity of stems and roots were on rise,as the increased of nitrogen application.It was beneficial to the growth of aromatic tobacco of ’ Yunnam Tobacco Basima 1 ’ （YNOTBS1） and made it possible to get higher yield and value when supplied with 75 kg/hm 2 nitrogen,while irrigated enough water.
