【摘要】 本文对豚草的次生代谢产物与土壤微生物之间的关系进行了研究。通过对不同月份豚草体内次生代谢产物——绿原酸和咖啡酸含量的测定，研究了它们在豚草中的含量动态变化过程。在对大豆地根区土壤微生物进行分析后，从中分离、纯化了一些菌种，并通过抑菌实验，研究了豚草次生代谢产物与土壤微生物的关系，结果为：1．豚草中绿原酸和咖啡酸的含量从5月份开始呈现出增加的趋势，到7月末达到最大，8月末它们的含量又趋于减少，并且在7月和8月份绿原酸和咖啡酸在豚草茎、叶中的含量大大高于豚草根中的含量。2．根据抑菌实验结果，可以得出豚草的次生代谢产物对土壤微生物具有一定的选择抑制作用。更多还原

【Abstract】 The relation between secondary metabolites of Ambrosia artemisiifolia and soil microorganism was studied. We systematically analyzed the dynamic change of Chlorogenic acid and Caffeic acid of A. artemisiifolia in different month. After carrying on research to the soil microorganism of root district of soybean, some microorganism were separated and purified from it. And through the restraining them experiments , we studied the relation of secondary metabolites of A. artemisiifolia and soil microorganism. The results showed as below:1.The contents of Chlorogenic acid and Caffeic acid of A. artemisiifolia increased from May, and reached the greatest by the end of July. Then the contents began to decrease in August. And the contents of Chlorogenic acid and Caffeic acid in the leaves and stems of A. artemisiifolia were higher than in the roots.2.According to the results of the restraining microorganism experiments, we got the conclusion that the secondary metabolites of A. artemisiifolia had certain selective inhibition on the soil microorganism.更多还原
