土壤环境对川白芷产量和品质的影响研究

目的研究土壤因子对川白芷药材产量和品质的影响。方法对川白芷道地产区四川省遂宁市15个不同采集地的川白芷药材产量性状、欧前胡素和异欧前胡素的量,以及相应生长地土壤基本养分和其他11种无机元素进行测定,通过相关分析研究土壤环境对川白芷产量及品质的影响。结果不同采集地川白芷的根质量、根长和周径以及欧前胡素和异欧前胡素量间均存在差异,其相应不同生长地土壤间基本养分和其他11种无机元素量也存在差异。川白芷根长与土壤有效磷的量、周径与土壤有机质的量、根质量与土壤有效磷及速效钾的量间均呈显著正相关。土壤全氮则与川白芷异欧前胡素的量间呈显著负相关。川白芷欧前胡素和异欧前胡素的量与土壤中其他11种无机元素的量间相关均不显著。结论土壤环境对川白芷产量及品质均有一定影响。

Effects of soil factors on yield and quality of Angelica dahurica var. formosana

Objective To study the effects of the soil factors on the yield and quality of Angelica dahurica originated from Sichuan Province.Methods The yield and contents of imperatorin,isoimperatorin,and other 11 different inorganic elements of A. dahurica,gathered from 15 different habitats of Suining in Sichuan Province were determined.And the basic soil nutrients and other 11 different mineral elements of the soil were analyzed.The effects of the soil factors on the yield and quality were analyzed through correlation analysis.Results The weight,length,circumference,and the contents of imperatorin and isoimperator in the roots of A.dahurica from different habitats were different.And the basic soil nutrients and other 11 different mineral elements of soil were different.The positive correlation between root length of A.dahurica,and soil available P content,root circumference of A.dahurica,and soil organic matter content,root weight of A.dahurica,and soil available P and K contents were all significant.The soil total nitrogen content had negatively significant correlation with the content of isoimperatorin.The correlation among the imperatorin,isoimperator contents of A.dahurica,and 11 other soil inorganic elements was not significant.Conclusion The soil factors have effects on the yield and quality of A.dahurica to some degree.
