摘　　要：目的研究土壤因子对穿心莲生长质量的影响。方法分别测定不同产地穿心莲中总内酯、总黄酮及醇溶性浸出物的含量,并分析相应土壤的理化性质。结果不同产地穿心莲的质量差异显著,土壤因子对穿心莲中成分的含量影响较大,其中对穿心莲总内酯含量直接作用最大的是速效磷、速效钾,间接作用最大的为硝态氮;穿心莲总黄酮与有机质相关性最大;醇溶性浸出物的含量与速效钾的直接作用最大。结论穿心莲适宜生长于中性、弱酸或弱碱性土壤中,且土壤对速效养分K、P及氮肥的高水平利用有助于穿心莲的生长和活性成分的蓄积,因此,可通过施加速效钾、速效磷等养分来提高穿心莲的培育质量,从而获得高产优质的穿心莲药材。OBJECTIVE To study the effects of soil factor on the quality of Andrographis paniculata （ Burm. f. ） Nees originated from different localities. METHODS The contents of terpene lactones, flavonoids and ethanol - soluble extractives in Andrographis paniculata gathered from different locations were compared. Physicochemical properties and mineral elements of soil were analyzed for studying the effects on quality of Andrographis paniculata through path and correlation analysis. RESULTS The quality of Androgra- phis paniculata gathered from different provinces was obviously different. Soil factors had great effect on its chemical component. The P, K had the greatest direct effect and the nitrate nitogen had the greatest indirect effect on them. There was large relativity between the flavonoids and organic matter. The content of ethanol - soluble extractives had highest - level links with available K. CONCLUSION Neutral and weak acid or weak alkaline soil are appropriate for its cultivation. Soil taking full advantage of available K, P and nitrogen is helpful for the growth of Andrographis paniculata and the accumulation of active ingredients. Studying the effects of soil factor on quality of Andrographis paniculata can be used to guide planting and its GAP management.
