- 摘要:
- 以承德地区野生和栽培柴胡为试材，采用微波消解-电感耦合等离子体质谱法和高效液相色谱法，分析讨论土壤与植株中矿质元素的相关性，柴胡皂苷a、柴胡皂苷d与土壤及植株中矿质元素的相关性，植株对矿质元素的富集能力，以期为野生驯化柴胡的规范化种植提供参考依据。结果表明：柴胡植株对其生境土壤Ca的富集能力较强，对N、Fe、Zn的富集能力居中，对Mg、Cu、Mn、P、K、Mo的富集能力较低。富集系数表现出Ca＞Fe＞Zn＞N＞Mg＞Cu＞Mn＞P＞K＞Mo的规律。根际土壤-柴胡植株系统中矿质元素与柴胡皂苷具有一定的相关性，根际土壤与柴胡植株矿质元素也具有一定的相关性；柴胡皂苷a含量、柴胡皂苷a+d含量与根际土壤Fe元素含量存在显著正相关（P＜0.05）；柴胡皂苷d含量、柴胡皂苷a+d含量与柴胡植株体内N元素含量存在显著正相关（P＜0.05）。综上可知，不同的栽培方式、生长年限、土壤环境等因素影响根际土壤-柴胡植株系统中对矿质元素富集效应及柴胡皂苷的累积。
- Abstract:
- Wild and cultivated Bupleurum chinense DC.in Chengde area were used as the test materials.Microwave digestion-inductively coupled plasma mass spectrometry (ICP-MS) and high performance liquid chromatography (HPLC) were used to analyze and discuss the correlation between soil and plant mineral elements,the correlation between saikosaponin a and saikosaponin d of Bupleurum chinense DC.and soil and plant mineral elements,and the enrichment ability of plant mineral elements,in order to provide reference for the standardized planting of wild domesticated Bupleurum chinense DC..The results showed that Bupleurum chinense DC.had a strong ability to enrich soil Ca,N,Fe,Zn in the middle,and a low ability to enrich soil Mg,Cu,Mn,P,K,Mo.The enrichment coefficient was Ca>Fe>Zn>N>Mg>Cu>Mn>P>K>Mo.There was a certain correlation between the mineral?elements and saikosaponin in the rhizosphere soil-plant system of Bupleurum chinense DC.,and there was also a certain correlation between the mineral elements in rhizosphere soil and Bupleurum chinense DC..The contents of saikosaponin a and saikosaponin a+d were significantly positively correlated with the content of Fe in rhizosphere soil (P<0.05).The contents of saikosaponin d and saikosaponin a+d were significantly positively correlated with the content of N element in Bupleurum chinense DC.plants (P<0.05).In conclusion,different cultivation methods,growth years,soil environment and other factors affect the enrichment of mineral elements and the accumulation of saikosaponin in the rhizosphere soil-Bupleurum chinense DC.system.
