目的:探讨广东中山地区异地栽培对苦参生长与氧化苦参碱含量的影响,为苦参在华南地区的推广种植提供依据。方法:2010~2012年连续3年于广东省中山市进行了苦参引种试验,测定苦参的株高、叶面积、根干重、根长等生长指标,HPLC法测定氧化苦参碱含量,采用灰色加权关联度理论和模糊数学中的层次评价法对9项主要生长指标进行综合分析。结果:引种的苦参与其主产区的参考系加权关联度为0.8545,二者的相似程度高;引种一年生苦参根氧化苦参碱含量为13.2784 mg/g,两年生含量为16.4779 mg/g,与原产地相比,一年生的含量持平,两年生比原产地的低28.67%,但比中国药典规定的含量分别高10.65%和37.32%。结论:引种苦参与主产地苦参相似度高,在广东省中山市有较强的适应性,可以在华南地区推广种植。
OBJECTIVE: To investigate the effects of cultivation in different places on the growth and the content of oxymatrine in Zhongshan district of Guangdong province, and provide the basis for the promotion of S. japonicus in southern China. Methods: The test of Sophora flavescens was conducted in Zhongshan City, Guangdong Province from 2010 to 2012. The growth indexes of plant, leaf area, root dry weight and root length of Sophora flavescens were determined. The contents of oxymatrine, Nine major growth indexes were analyzed comprehensively by using gray weighted relational theory and hierarchical evaluation method in fuzzy mathematics. Results: The weighted correlation coefficient of the reference frame of introduced Sophora flavescens to its main producing area was 0.8545, the similarity between them was high. The annual oxymatrine content of Sophora flavescens was 13.2784 mg / g and the biennial content was 16.4779 mg / g Compared with the place of origin, the annual content is the same, two years lower than the origin of 28.67%, but higher than the Chinese Pharmacopoeia content of 10.65% and 37.32% respectively. Conclusion: The introduction of Sophora flavescens participates in the main origin of Sophora flavescens similarity is high, in Zhongshan City, Guangdong Province has a strong adaptability, you can promote the planting in southern China.
