摘要/Abstract

摘要： 以武清区种植的金叶榆、金枝槐、金叶白蜡林地为样地,对其土壤盐渍化程度、树高、茎粗、冠幅、年轮等进行了分析,比较了3种金叶树的生长差异,以便为金叶植物的合理栽培运用提供依据。结果显示：样地中金叶榆近5年的株高生长量比金叶槐高73.4%,比金叶白蜡高82.2%;金叶榆近5年的茎粗生长量比金叶槐高48.0%,比金叶白蜡高68.7%;金叶榆的冠幅比金叶槐高18.2%,比金叶白蜡高107.1%。从植株近5年的年轮生长量分析,金叶榆和金枝槐年轮生长量呈增长趋势,其中金叶榆增长得更多;金叶白蜡生长量最小。因此,在天津市武清区样地的轻度盐碱土上,3种金叶植物的生长量有明显区别,从株高、茎粗、冠幅3个方面看,金叶榆生长量最高,金叶槐次之,金叶白蜡最低。

Abstract: The difference in growth of three varieties of gold leaf Plants growing in saline-alkali soil in Wuqing District of Tianjin were compared to provide a basis for the plants rational cultivation and application. The soil plots with Ulmus pumila cv. Jinye, Sophora japonica cv. Golden Stem and Fraxinus chinensis Roxb. grown in Wuqing District were selected as sample plots, and the soil pH, soil salinity, tree height, stem diameter, crown and rings were analyzed. The results show that the tree height of Ulmus pumila cv. Jinye.in the last five years was 73.4% higher than that of Sophora japonica cv. Golden Stem, and 82.2% higher than that of Fraxinus chinensis Roxb.; The stem diameter of Ulmuspumila cv. Jinye in the last five years was 48.0% higher than that of Sophora japonica cv. Golden Stem. and 68.7% higher than that of Fraxinus chinensis Roxb.; the crown diameter of Ulmus pumila cv. Jinye, in the last five years was 18.2% higher than that of Sophora japonica cv. Golden Stem, and 107.1% higher than that of Fraxinus chinensis Roxb.; The annual ring of Ulmuspumila cv. Jinye and Sophora japonica cv. Golden Stem grew more and more quickly in last five years in Wuqing District plant, and the annual ring of Ulmus pumila cv. Jinye increased more.The growth of the annual ring of the Fraxinus chinensis Roxb. was the least. On the mild saline-alkali soil land in Wuqing District there are obvious differences in growth between three kinds of golden leave tree. In growth of tree height, stem diameter and crown diameter Ulmus pumila cv. Jinye comes first, and then Sophora japonica cv. Golden Stem, the Fraxinus chinensis Roxb. is the last.

Key words: saline-alkali soil, Ulmus pumila cv.Jinye, Sophora japonica cv. Golden Stem, Fraxinus chinensis Roxb., growth
