土壤盐碱程度对不同种类彩叶植物生长的影响
|
摘要
为了解不同种类彩叶植物对盐碱程度的耐盐性,以金叶槐、金叶榆、紫叶李、紫叶矮樱、红叶碧桃、红叶臭椿6个品种为试材,分析了植株4项生长指标。结果显示:在非盐碱地上,生长最好的为金叶榆,紫叶矮樱生长最差;在轻度盐碱地上:生长最好的为金叶榆和金叶槐,紫叶矮樱生长最差;在中度盐碱地上:生长最好的为金叶榆和金叶槐,紫叶矮樱生长最差,与轻度盐碱地的一致。综合隶属函数分析显示,不同种类彩叶植物在非盐碱地上与轻度盐碱地、中度盐碱地上适应性为金叶槐>金叶榆>红叶碧桃>紫叶李>红叶臭椿>紫叶矮樱。
In order to understand the salinity tolerance of colored leaf trees, the four growth indexes and their growth characteristics were researched with 6 varieties Sophora japonica cv. Golden Stem, Ulmus pumila cv. Jinye, Prunus cerasifera,Prunus×Cistena Pissardii, Amygdalus persica f.atropurpurea, Ailanthus altissima. The results showed that the best growth was Ulmus pumila cv. Jinye on the non-saline soil, and the growth of the Prunus cerasifera was the worst. On the mild saline-alkali soil, the best growth was the Ulmus pumila cv. Jinye and the Sophora japonica cv. Golden Stem, while the Prunus cerasifera was the worst growth. On the saline-alkali ground: the best growth is the Ulmus pumila cv. Jinye and the Sophora japonica cv.Golden Stem, while the Prunus cerasifer dwarf cherry had the worst growth, which is consistent with the mild saline-alkali land.The comprehensive membership function analysis showed that the adaptability of different kinds of colorful leaf plants on non-salt-alkali soils, mild saline-alkali soils and moderate saline-alkali soils was Sophora japonica cv. Golden Stem>Ulmus pumila cv. Jinye>Amygdalus persica f.atropurpurea>Prunus cerasifera>Ailanthus altissima>Prunus×Cistena Pissardii.
