摘要:
为了了解植物的耐盐性,以天津常见的6个彩叶树品种为试材,研究了年轮动态变化和生态反应值.结果显示,在中度盐碱地上,金叶榆的生态反应值最小,其次是紫叶李;在轻度盐碱地上,生态反应值均降低,金叶榆仍最小,其次是紫叶李和金叶槐;在非盐碱地上,植物的生态反应值最小,生态反应值均小于0.1.因此,认为金叶榆对盐碱环境的适应性最强,紫叶李次之,红叶臭椿、太阳李和金叶槐适应性中等,紫叶矮樱适应性最差.

Abstract:
In order to understand the salt tolerance of plants, the annual growth dynamics and ecological response of six color-leaf tree species commonly planted in Tianjin were studied. The results showed that in moderate saline-alkali land, the ecological response value of Ulmus pumila cv. Jinye was the lowest, followed by Prunus cerasifera Ehrhar f. atropurpurea (Jacq.) Rehd; in light saline-alkali land, the ecological response values decreased in all the species studied, U. pumila had the minimum value, followed by P. cerasifera and Sophora japonica cv. Golden Stem; and in non-salt alkaline soils all the plants had the lowest ecological response value (<0.1). It was thus concluded that of the six tree species studied U. pumila cv. Jinye had the strongest adaptability to the saline-alkali environment, followed by P. cerasifera Ehrhar f. atropurpurea (Jacq.) Rehd; Ailanthus altissima cv. Hongye, P. salicina and S. japonica had a moderate adaptability; and the adaptability of P. cistena was the poorest.
