摘要
为明确湘西烟地翻压豆科绿肥后的适宜减施氮量,以箭舌豌豆为材料,研究了不同减施氮量对烤烟农艺性状、经济性状、物理特性和化学成分的影响.结果表明：翻压绿肥箭舌豌豆后适量减施氮肥,可提高烤烟产量和产值,提高烟叶物理性状,烟叶化学成分更加协调.翻压绿肥箭舌豌豆还田可减施氮量9～18kg/hm^2,以减施氮量9kg/hm2较为适宜.
In order to get the proper reducing rate of the nitrogen fertilizer application in Xiangxi tobacco fields after the green manure,using vetch as material,this paper studied the effect of different N application reduction rate on the agronom-ic characters,economic characters,physical properties and chemical composition on flue-cured tobacco.Results show that the yield,output value and physics properties of flue-cured tobacco improve along with the reduction of proper amount of nitrogen application when turning under vetch green manure,besides,the chemical components are well-balance.Vetch green manure returning can reduce the amount of nitrogen 9 -18 kg /hm2 ,and the best nitrogen reduction rate is 9 kg/hm2.
