ICP-AES technology was used to determine the major mineral elements content and analyze the dynamic and cumulative amount of the main absorption during the growth and development stage of the Kinlowii organs plant. The result showed as follows: (1)The mineral elements were changing in the different stage. The highest mineral element accumulation of K, P, Ca, Mg, Fe, Mn, Zn, Cu and Mo occured in October, their values are 3,695.90, 445.88, 9,649.32, 2,652.10 mg per plant, 324,398.29, 40,188.65, 22,383.13, 36,054.58 and 61.95 microg per plant separately. But the highest value of B occured in September and the value was 8 690.97 microg per plant. (2) the distribution of mineral element in the kirilowii plant was not even, the contents of K and P were highest in kirilowii peel, they can reach 27.65 and 2.63 mg.g-1. The contents of Ca and Mg were highest in kirilowii leaves, they can reach 33.28 and 5.73 mg .g-1. The contents of Fe, Mn, B were highest in kirilowii roots, they can reach: 4,069.74, 127.73, 24.75 microg.g-1. The contents of Zn and Mo were highest in kirilowii seeds, they can reach 68. 61 and 1.07 microg.g-1. (3) the cumulation dynamic of mineral elements in kirilowii plant during the whole stages was S-type, and the plant showed rapid growth from the mid-July to mid-Spetember. The information of this study will supply a scientific data for the quality assessment and rational fertilization of kirilowii plant and harvestment.
采用电感耦合等离子体发射光谱法（ICP - AES）测定祁连獐牙菜器官生长发育阶段主要矿质元素含量，并分析其主要吸收动态及累积量。结果如下：（1）矿质元素在不同阶段发生变化。钾、磷、钙、镁、铁、锰、锌、铜和钼的矿质元素积累量最高值出现在10月，其值分别为每株3695.90、445.88、9649.32、2652.10毫克，每株324398.29、40188.65、22383.13、36054.58和61.95微克。但硼的最高值出现在9月，值为每株8690.97微克。（2）祁连獐牙菜植株中矿质元素分布不均，祁连獐牙菜果皮中钾和磷含量最高，可达27.65和2.63毫克·克⁻¹。祁连獐牙菜叶片中钙和镁含量最高，可达33.28和5.73毫克·克⁻¹。祁连獐牙菜根中铁、锰、硼含量最高，可达4069.74、127.73、24.75微克·克⁻¹。祁连獐牙菜种子中锌和钼含量最高，可达68.61和1.07微克·克⁻¹。（3）祁连獐牙菜植株在整个生育期矿质元素累积动态呈“S”型，植株在7月中旬至9月中旬生长迅速。本研究信息将为祁连獐牙菜的质量评价、合理施肥及采收提供科学数据。
