本文利用光学显微技术研究了盐生植物海乳草叶片的形态解剖学特征。结果表明。海乳草是典型的泌盐植物。生长在两种不同盐浓度环境中的海乳草、表现出显著的性状差异，在高盐湿生环境中，植株匍匐、叶片小、轻度肉质化、紫红色、全栅型，泌盐结构为海榄类型。在低盐旱生环境中，植株直立、叶片大、双栅型，泌盐结构为补血草－－柽柳属类型 In this paper, morphological anatomy of halophyte leaves of halophytes was studied using optical microscopy. The results show. Sea milkweed is a typical salt-producing plant. Sea milkweed, grown in two different salt concentrations, showed significant trait differences. In high salt and wet environment, plant creeping, small leaves, mild succulent, purple, all-grid, For the sea type. In the low-salt and drought environment, the plants are erect, with large leaves, double-gated, and salt-tolerant structures of Limonium-Tamarix
