Abstract: 【Objective】 To explore the effects of sowing, cuttage and root-cutting on the agronomic traits,yield and quality of essential oil of lavender. 【Methods】 Xinnong Xun 2 was used as the experimental material to compare the differences of agronomic traits, essential oil yield and quality in different reproduction modes at different development stages. 【Results】 In the same growth period, the agronomic traits such as crown width, stem thickness, leaf length, plant height, number of tassels and yield of number of floral whorl of cutting seedlings were better than those of root-cutting seedlings and seed seedlings, the yield of essential oil of cutting seedlings was the highest. Annual and biennial lavender’s yield of essential oil was 35.54 and 129.00 kg/hm² respectively. The linalool, linalyl acetate and lavandulyl acetate of biennial cutting seedlings were 43.53%, 16.56% and 10.87% respectively. The agronomic traits, essential oil yield and quality of biennial lavender were better than those of annual lavender under the same reproduction mode. 【Conclusion】 The agronomic traits, essential oil yield and quality of cutting seedlings are better than those of root seedlings and seed seedlings, so it is suggested that cutting seedlings should be planted in lavender field production.
