L. is known as an industrial crop in the world as it possesses an essential oil that is extensively used in the perfumery and flavor industries. The crop performance is influenced by the planting/sowing method (SM) and seeding rate (SR); however, the effects of these variables on biomass yield and quality of the essential oil of remain unclear. As a comparatively new crop, the responses of to different SMs and SRs have not been studied in the mild temperate eco-region. Thus, the biomass and essential oil yield response of (variety 'Himgold') to SM (line sowing and broadcasting) and SR (at 2, 3, 4, 5, and 6 kg ha) were investigated. The overall fresh biomass of ranged from 16.86 to 28.13 Mg ha, while the essential oil concentration in fresh biomass varied from 0.23% to 0.33%. Irrespective of the SR, the broadcasting method produced significantly ( ≤ 0.05) higher fresh biomass yield by approximately 15.8% and 7.6% compared with line sowing during 2016 and 2017, respectively. An increase in biomass yield was noted as the SR increased up to 4 kg ha. The SR at 4 kg ha registered approximately 41.9%-56.1% and 3.3%-10.3% higher biomass yield than the SR at 2 and 6 kg ha, respectively. No significant ( ≥ 0.05) differences in essential oil concentration in fresh biomass were observed due to the different SMs and SRs. Thus, may be sown by the broadcasting method in the mild temperate eco-region with an SR of 4 kg ha.
因其拥有一种广泛用于香水和香料行业的精油，L. 在世界上被视为一种经济作物。作物表现受种植/播种方法（SM）和播种量（SR）影响；然而，这些变量对L. 生物量产量和精油质量的影响仍不清楚。作为一种相对较新的作物，在温和温带生态区域尚未研究过L. 对不同SM和SR的反应。因此，研究了L.（品种‘Himgold’）对SM（条播和撒播）和SR（2、3、4、5和6千克/公顷）的生物量和精油产量反应。L. 的总鲜生物量范围为16.86至28.13吨/公顷，而鲜生物量中的精油浓度在0.23%至0.33%之间变化。无论SR如何，与2016年和2017年的条播相比，撒播方法分别显著（P≤0.05）提高了约15.8%和7.6%的鲜生物量产量。随着SR增加至4千克/公顷，生物量产量有所增加。4千克/公顷的SR分别比2千克/公顷和6千克/公顷的SR高出约41.9% - 56.1%和3.3% - 10.3%的生物量产量。由于不同的SM和SR，未观察到鲜生物量中精油浓度有显著（P≥0.05）差异。因此，在温和温带生态区域，L. 可以采用撒播方法，播种量为4千克/公顷。
