硝态氮和铁态氮是植物吸收的两种主要氮素形式，但两者吸收，运输和同化过程很不相同。黄连CoptischinesisFranch。主要有效成分小檗碱分子中含有氮，因而氮素营养对黄连的生长及有效成分小檗碱的形成具有重要意义。今通过不同氮源试验，观察研究黄连生长和小檗碱含量的变化，?
Nitrate nitrogen and iron nitrogen are the two main forms of nitrogen absorption by plants, but their processes of absorption, transportation and assimilation are very different. Huang Lian CoptischinesisFranch. The main active ingredient berberine contains nitrogen, so nitrogen nutrition has important significance for the growth of berberine and the formation of berberine, an effective ingredient. Now through different nitrogen source tests, observe changes in the growth and berberine content of Coptis,?
