以山豆根种子为试材,研究4种不同种植密度对山豆根生长及不同部位总黄酮、苦参碱和氧化苦参碱含量的影响。结果表明:处理C(667m~2种植3 000株)的山豆根地下部分产量最高,与其它处理差异不显著;处理D(667m~2种植3 500株)的山豆根根中有效成分含量最高,与其它处理差异显著。综合分析,山豆根在667m~2种植3 000~3 500株更有利于产量和质量形成。 The effects of four different planting densities on the growth of root and the content of total flavonoids, matrine and oxymatrine in different parts were studied using the roots of Radix solanum as test materials. The results showed that the yield of the roots was the highest in the treatment of C (667m ~ 2 with 3 000 plants), and the difference was not significant with other treatments. The content of active ingredients Highest, and significant difference with other treatments. According to the comprehensive analysis, the yield and quality of Shandougan were more favorable to the planting of 3 000 ~ 3 500 in 667m ~ 2.
