摘要
应用ICP-AES技术,测定并分析了野菊花不同器官矿质元素含量、累积量和比例。结果显示:(1)野菊花常量矿质元素中K含量最高,根、茎、叶、花K含量分别达到15.84,17.74,31.52,37.55mg.g-1,微量元素中Fe含量最高,根、茎、叶、花Fe含量分别为3 219.90,433.36,1 519.46,1 426.63μg.g-1。(2)野菊花茎K,P,Ca,Mg,Mn,Zn,Mo累积量最大,分别达240.61,19.67,74.87,18.31mg.株-1,893.00,1 039.08,2.85μg.株-1,野菊花根Na,Fe,Cu累积量最高,分别为11.51mg.株-1,11 725.27,235.24μg.株-1。(3)野菊花各器官K∶P,Ca∶Mg,Fe∶Mn,Zn∶Cu差异较大。结果明确了野菊花不同器官矿质元素差异并为野菊花的合理施肥提供了新的科学依据。
ICP-AES technique was used to analyse the mineral elements in different organs of Chrysanthemum indicum L.. The results show that： （1） The content of K in root, stem, leaves and flower was the highest among macroelements, and can respectively reach to 15.84, 17.74, 31.52 and 37. 55 mg·g^-1, while the content of Fe was the highest in microelements in root, stem, leaves and flower, and can respectively reach to 3 219. 90, 433.36, 1 519. 46, and 1 426.63 μg·g^-1. （2） The accumulation of K, P, Ca, Mg, Mn, Zn and Mo was highest in stem of Chrysanthemum indicurn L. , and can respectively reach to 240. 61, 19.67, 74.87, 18. 31 mg·plant^-1 and 893. 00, 1 039.08, 2.85 μg·plant^-1, while the accumulation of Na, Fe and Cu was highest in root, and can respectively reach to 11.51 mg·plant^-1, 11 725.27 μg·plant^-1, and 235.24 μg·plant^-1. （3） The proportion of K ： P, Ca ： Mg, Fe ： Mn, Zn ： Cu was varied in different organs. The results of the study pinpoint the mineral elements in different organs of Chrysanthemum indicum L. and will be a scientific basis for fertilization.
