摘要: 为了解不同类型盐碱地对彩叶植物的影响,以8种彩叶植物为试材,通过株高、冠幅、基径、胸径等指标的测定和各指标与综合分析结果的相关性分析,研究了天津市3种土壤中彩叶植物耐盐性生长指标的变化。结果显示:非盐碱地上,仅植株的胸径指标与综合评价结果显著相关,相关系数为0.921;轻度盐碱地上,植株的株高、冠幅、基径3个指标与综合评价结果显著相关,相关系数分别为:0.923、0.956、0.927;中度盐碱地上,植株的株高、冠幅、基径、胸径均与综合评价结果显著相关,相关系数分别为0.923、0.956、0.927、0.918。本文还对耐盐性评价指标的选择、影响因素进行了讨论。

Abstract: In order to understand the effects of different saline land on colored-leaf plants, the plant height, crown width, basal diameter, breast diameter were measured and the correlations between each index and comprehensive analysis results were analyzed with eight kinds of colored-leaf plants. The changes of salt-tolerant growth index in three types of soil in Tianjin were studied. The results showed that on the non-saline soil only the breast diameter of the plant was significantly correlated with the comprehensive evaluation result, and the correlation coefficient was 0.921; on the mild saline-alkali soil plant height, crown width and base diameter were significantly correlated with the comprehensive result, and the correlation coefficients were 0.923, 0.956, 0.927 and on the moderate saline-alkali soil all indexes were significantly correlated with comprehensive result, and the coefficients were 0.923, 0.956, 0.927, 0.918. The selection of indicators for salt-tolerant evaluation was also discussed.
