摘　　要：二色补血草(Limonium bicolor)是我国北方较为常见的野生植物资源,具有易繁殖、管理简单粗放、花期较长、耐盐碱、耐干旱等特点,在鄂尔多斯市园林绿化中具有广泛的应用前景。文章对二色补血草在不同水肥条件下的生长量和生长状态进行研究,通过盆栽试验条件,设置不同灌水和施肥处理,研究水肥耦合对二色补血草生长的影响,以进一步掌握二色补血草生长习性,为今后鄂尔多斯市园林绿化引种提供管理数据。结果表明:水分和施肥量的增加有利于二色补血草的生长,当土壤含水率为28%、N施肥量为42 ppm时,二色补血草生长状态最佳。Limonium bicolor,a common wild plant resource in northern China,is known for its easy propagation,simple and extensive management,long flowering period,salt-alkali tolerance,and drought resistance,making it widely applicable in the landscape greening of Ordos City.This study investigates the growth and condition of Limonium bicolor under different water and fertilizer conditions.Through pot experiment settings with various irrigation and fertilization treatments,the study explores the impact of water and fertilizer coupling on the growth of Limonium bicolor to further understand its growth habits and provide management data for future introduction in the landscape greening of Ordos City.The results indicate that increased water and fertilization are beneficial to the growth of Limonium bicolor,with the optimal growth conditions achieved at a soil water content of 28%and an N fertilization rate of 42 ppm.
