| 摘要: |
| 调查和分析测定同一产区不同土壤类型的黄花蒿土壤和植株不同部位的养分含量及青蒿素含量,并对其进行相关分析和因子分析,结果表明,青蒿素含量与土壤Ca的含量有显著的正相关关系,与根N、茎N素含量以及植株地下部和地上部的N素含量比有显著的负相关关系,与茎部和叶部的N素含量比有极显著负相关关系; 黄花蒿植株叶片的N含量与土壤P含量有显著的正相关关系; 影响青蒿素含量的主要因子是黄花蒿植株体内的养分含量,其次是土壤的养分含量以及土壤和植株等综合因子。通过施肥、适当补充土壤中的Ca和P素营养,改善土壤养分状况等各种途径来调节植株体内的养分,降低地下部和地上部的N素含量比值,茎叶部N素含量比值,提高青蒿素的含量,增施K肥,有利于黄花蒿的生长。 |

| Abstract: |
| The nutrient contents in diferent types of soil and diffferent parts of Artomisia annul plant and the contents of artemisinin were investigated and analysed. The correlation and factor analysis indicated respectively that there was a notable positive correlation between the content of artemisinin and soil Ca,a notable negative correlation between the content of and artemisinin and root N,stem N and the ratio of N content in roots to that in the overground parts of the plant,a marked negative correlation between the ratio of stem N to leaf N; And a notable positive correlation between the content of leaf N and soil P; The main factors affecting artemisinin accumulation were nutrient content in A.annul plant itself,the contents of the nutrient elements in soil and integrative factor between the soil and the plant. It was beneficial to the growth of A.annul and artemisinin accumulation by fertilizing,supplying to Ca,P properly,improving the nutrient status of soil and so on,reduing the ratios of N in the roots to N in the stems and N in the stems to N in the leaves,adjusting the plant nutrient content in the plant.Supplying to fertilizer K can also enhance the growth of A.annul. |
