不同肥料处理下黄连生长指数分析

Analysis of Growth Index of Coptis chinensis Franch.Under Different Fertilizer Treatments

以黄连为试材,对黄连苗施用有机肥、微生物菌肥、化肥等不同肥料,并跟踪观测黄连苗根系在长度、体积、分根及粗度,叶片数、株高、叶绿素相对含量及氮素含量等多个指标,研究了不同肥料对黄连苗生长的影响,以期为科学种植黄连提供参考依据。结果表明:有机肥、微生物菌肥均可促进黄连苗根系在长度、体积、分根及粗度等多个方面生长,可以在一定程度上促进黄连苗叶片数的增加及植株的长高,增加叶片叶绿素相对含量及氮素含量,有机肥和微生物菌肥搭配使用对黄连苗生长的促进比单独使用有机肥或单独使用菌肥效果更好。

Taking Coptis chinensis Franch.as experimental material, the method of applying different fertilizers such as organic fertilizer, microbial fertilizer and chemical fertilizer to Coptis chinensis Franch.seedlings, and tracking and observing multiple indexes such as length, volume, root division and coarseness, leaf number, plant height, chlorophyll relative content and nitrogen content of Coptis chinensis Franch.seedlings.The effects of different fertilizers on the growth of Coptis chinensis Franch.seedlings were studied, in order to provide reference for scientific planting of Coptis chinensis Franch.seedlings.The results showed that both organic fertilizer and microbial fertilizer could promote the growth of root system of Coptis chinensis Franch.seedlings in many aspects such as length, volume, root division and coarseness, increase the number of leaves and plant height, and increase the content of chlorophyll and nitrogen in leaves to a certain extent.The combination of organic fertilizer and microbial fertilizer could promote the growth of Coptis chinensis Franch.seedlings better than the use of organic fertilizer or bacterial fertilizer alone.
