为了解薰衣草在宜昌高海拔地区引种栽培表现,以‘法国蓝’薰衣草为材料,观测株高、冠幅、分头数、花序平均长度、花序平均层数、花序平均花量、花冠平均直径、单株花量以及花期等9个农艺性状,并记录相关气象因子,对相关数据进行单因素方差分析和皮尔逊相关性分析。结果显示:9个农艺性状的变异系数范围为2.45%~50.95%,除花冠平均直径外其余薰衣草农艺性状在不同年度间均存在显著差异(p<0.05);花量与株高、冠幅和分头数间均存在相关性;花序平均层数和花序平均花量与年降雨量间呈极显著负相关。在薰衣草栽培过程中,可通过优化栽培措施提高薰衣草的生物量,亦可通过控水栽培来提高花序平均层数和平均花量,进而提高薰衣草花量和观赏价值。
To understand performance of lavender in high altitude area of Yichang, used Lavandula angustifolia ''French Blue'' as the material, 9 agronomic traits were measured, including plant height, crown width, number of heads, average length of inflorescence, average number of layers in inflorescence, average number of flowers in inflorescence, average diameter of corolla, number of flowers per plant and flowering period, and the meteorological factors were recorded. One-way ANOVA and Pearson correlation analysis were performed. The results indicated that the variation coefficient of 9 agronomic traits was ranged from 2.45% to 50.95%, and there were significant differences(p<0.05) in agronomic traits of lavender in different years except the average diameter of corolla. There were correlations between flower number and plant height, crown width and head number; and the average number of layers in inflorescence and the average number of flowers in inflorescence were significantly negatively correlated with the annual rainfall. In the process of lavender cultivation, the biomass of lavender can be increased by optimizing cultivation measures, and the average layers number of inflorescence and the average number of flowers can be increased by controlled water cultivation, so as to improve the flower number and the ornamental value of lavender.
