摘　　要：为紫苏新品种高效栽培合理施用氮肥提供依据,采用田间试验研究不同施氮量对奇苏2号和奇苏3号紫苏品种产量和品质的影响。结果表明:施氮量对紫苏农艺性状、产量及生物量均有较大影响;施氮量<20kg/667m^2时,紫苏的主要农艺性状随施氮量增加呈上升趋势,之后呈下降趋势。其中,奇苏2号施氮量为18.74kg/667m^2时的产量最高,为79.92kg/667m^2;奇苏3号施氮量为15.66kg/667m^2时的产量最高,为63.69kg/667m^2。施氮肥对紫苏的含油率和脂肪酸含量影响不显著。The effects of different nitrogen application rate on yield and quality of Qisu 2 and Qisu 3 are studied by a field test to provide the basis for rational nitrogen application in high-efficient cultivation of new P.frutescens varieties.Results：Nitrogen application rate has the great effects on agronomic traits,yield and biomass of Qisu 2 and Qisu 3.Main agronomic traits of two P.frutescens varieties present a first rising and then declining trend with increase of nitrogen application rate when nitrogen application rate is20kg/667m^2.The yield of Qisu 2is the highest（79.92kg/667m^2）when nitrogen application rate is 18.74kg/667m^2 but the yield of Qisu 3 is the highest（63.69kg/667m^2）when nitrogen application rate is 15.66 kg/667m^2.Applying nitrogen has no significant effects on oil and fatty acid content of P.frutescens varieties.
