目的:研究青蒿素含量与土壤养分的相关性,生成青蒿素含量的空间分布图。方法:利用GPS定位,采用地统计学对青蒿道地产区重庆市酉阳县一块种植田的青蒿素含量的空间趋势和空间变异性进行分析。结果:变量均近似正态分布且具有较好的空间结构特征;土壤有机质和全氮对与青蒿素含量的相关系数分别是0.325和0.126。结论:本研究结果为青蒿规范化种植的空间管理措施提供参考。
Objective: To study the correlation between the content of artemisinin and soil nutrients and the spatial distribution map of artemisinin content. Methods: The spatial and temporal variability of artemisinin content in a field planted in Youyang County, Chongqing Municipality was analyzed by geostatistics using GPS positioning. Results: The variables were nearly normal distribution and had good spatial structure. The correlation coefficients of soil organic matter and total nitrogen to artemisinin content were 0.325 and 0.126, respectively. Conclusion: The results of this study provide a reference for space management measures for standardized cultivation of Artemisia annua.
