摘要

摘要:
为深入了解植物在适应环境的过程中逐渐形成的性状差异及其影响因素，选择太行山地区常见的7种药用植物挂金灯（Alkekengi officinarum）、蕺菜（Houttuynia cordata）、艾（Artemisia argyi）、活血丹（Glechoma longituba）、枸杞（Lycium chinense）、忍冬（Lonicera japonica）和薄荷（Mentha canadensis）为研究对象，通过测定植物光合、结构性状及土壤理化性质，分析不同植物性状差异及其对土壤因子的响应。结果表明：太行山7种药用植物中，薄荷和枸杞表现出较优的性状组合，其光合速率与叶干物质含量较高，蒸腾速率与比叶面积较低，且枸杞的根冠比显著高于其他植物。Spearman相关性分析表明，叶片蒸腾速率、气孔导度与叶干物质含量、植物单株生物量呈显著负相关，胞间CO₂浓度与叶片相对含水率呈显著正相关，水分利用效率与比叶面积呈显著负相关。太行山坡地7种药用植物性状变化主要来源于种间变异，光合和结构性状种间变异系数为11.08%~164.42%，除植物单株生物量和根冠比表现为强变异外，其他性状均表现为中等变异；不同性状种内变异系数平均为28.75%，处于较低水平。植物性状与土壤因子的RDA分析结果表明，土壤pH、黏粒含量对植物性状变异的解释率之和达72.30%，是影响7种药用植物性状特征的主要土壤因子，且电导率与土壤pH、黏粒含量间呈显著正相关；通过因子分析得出，有机碳、全氮、碳氮比与挂金灯、薄荷、艾、枸杞性状变化的相关性较大，土壤含水量与活血丹性状变化相关性较大。综上，太行山地区7种药用植物性状差异明显，可以通过土壤pH、土壤颗粒组成及电导率等影响植物性状，应针对特定的植物品种，进行有差别的土壤改良。

Abstract:
In order to understand the trait differences of plants gradually formed during the process of adapting to the environment and their influencing factors, seven medicinal plants commonly found in Taihang Mountains were selected as the research objects, including Alkekengi officinarum, Houttuynia cordata, Artemisia argyi, Glechoma longituba, Lycium chinense, Lonicera japonica and Mentha canadensis. The plant photosynthesis, structural traits and soil physicochemical properties were measured to analyze the trait differences and their responses to soil factors. The results showed that among the seven medicinal plants, Mentha canadensis and Lycium chinense showed superior trait combinations, with higher photosynthetic rate and leaf dry matter content, and lower transpiration rate and specific leaf area; the root-to-shoot ratio of Lycium chinense was significantly higher than other plants. Spearman correlation analysis showed that leaf transpiration rate and stomatal conductance were significantly negatively correlated with leaf dry matter content and plant biomass per plant. There was a significant positive correlation between intercellular CO₂ concentration and leaf relative water content, while there was a significant negative correlation between water use efficiency and specific leaf area. The changes in the traits of the seven medicinal plants on Taihang Mountain slope mainly came from interspecific variation, with the variation coefficient of photosynthetic and structural traits ranging from 11.08% to 164.42%. Except for strong variation in plant biomass per plant and root-to-shoot ratio, all other traits showed moderate variation. The average intraspecific variation coefficient of different traits was 28.75%, which was at a low level. The RDA analysis of plant traits and soil factors showed that the sum of the explanatory rates of soil pH and clay content on plant trait variation was 72.30%, which was the main soil factor affecting the traits of the seven medicinal plants, and the soil conductivity was significantly positively correlated with soil pH and clay content. Through factor analysis, the organic carbon, total nitrogen, and C/N ratio were more correlated with the changes of the traits of Alkekengi officinarum, Mentha canadensis, Artemisia argyi and Lycium chinense, and the soil moisture was more correlated with that of Glechoma longituba. In summary, the traits of the seven medicinal plants were obviously different in Taihang Mountains, which could be affected by soil pH, soil particle composition, soil conductivity, and so on. Differentiated soil improvements should be carried out for specific plant varieties.
