摘要: 为筛选出适宜在天津轻度盐碱地栽植的彩叶植物,以光皮大叶榆、豆梨和紫叶紫荆为试材,测定了在轻度盐碱地上的株高、冠幅、基径、胸径4项生长指标。结果显示:光皮大叶榆株高相对生长量(0.49 m)最高,其次是豆梨(0.42 m)、紫叶紫荆(0.35 m);豆梨冠幅相对生长量(21.76 cm)最大,其次是紫叶紫荆(17.06 cm)、光皮大叶榆(10.42 cm);豆梨基径相对生长量(2.28 cm)最大,其次是光皮大叶榆(1.21 m)、紫叶紫荆(1.07 cm);豆梨胸径相对生长量(1.78 cm)最大,其次是光皮大叶榆(1.22 cm)、紫叶紫荆(1.04 cm)。隶属函数综合分析显示,豆梨在武清区轻度盐碱地上生长最好。

Abstract: In order to screen out new varieties of colorful leaf plants suitable for planting in saline soil in Tianjin, the relative plant heights, relative crown width, relative basal diameter and relative DBH in light saline soil were determined by using the Ulmus pumila varietas, Pyrus calleryana and Cercis canadensis Forest Pansy. The results showed that: from analysis of relative growth of plant height, Ulmus pumila varietas(0.49 m)was the largest, followed by Pyrus calleryana(0.42 m)and the lowest was Cercis canadensis Forest Pansy(0.35 m); from analysis of relative growth of width, Pyrus calleryana(21.76 cm)was the largest, followed by Cercis canadensis Forest Pansy(17.06 cm)and Ulmus pumila varietas(10.42 cm)was the smallest; from analysis of relative growth of base diameter, Pyrus calleryana(2.28 cm)was the largest, followed by Ulmus pumila varietas (1.21 m), and Cercis canadensis Forest Pansy(1.07 cm)was the smallest; from analysis of relative growth of DBH, Pyrus calleryana(1.78 cm)was the largest, Ulmus pumila varietas(1.22 cm)was the second, and Cercis canadensis Forest Pansy(1.04 cm)was the smallest. The comprehensive analysis of membership function showed that Pyrus calleryana is more suitable to grow on mild saline land in Wuqing district.
