Abstract:
【Objective】 To study the distribution characteristics of mineral elements in raisins in Turpan and their correlation with the parents soil.
【Methods】 The research objects were the Centennial Seedless raisins and their soil from 4 vineyards in Hongliuhe (Hong), Hailiqihan Manor (Hai), Research Institute of Grape and Melon (Ins), and Pizhan township (Pi) in Turpan. Inductively coupled plasma atomic emission spectrometry (ICP-MS) was used to determine the contents of 26 mineral elements in the samples.
【Results】 The distribution pattern of soil mineral elements was relatively consistent among vineyards and between years, and the contents were Al>Fe>Ca>Na>K>Mg>Ti>Mn>Ba>Sr>V>Rb>Zn>Cu>As>Ce>Li>Cr>Y>Ni>Pb>La>Co>Sc>Cs>Mo, and there was a strong correlation between the mineral elements of the top soil and the parent soil. The mineral content of raisins showed different magnitudes, K (≥10,000 mg/kg); Ca, Mg, Na (1,000-100 mg/kg); Fe, Al (100-10 mg/kg); Sr, Rb, Cu, Mn, Ti, Zn(10-1 mg/kg); Ba, Mo, Li (1-0.1 mg/kg); Cr, V, Ni, Pb, As, Ce, Cs, Co, La, Y (0.1-0.01 mg/kg); Sc (<0.01 mg/kg). The enrichment of major elements in raisins in the four regions was K, Ca, Mg (Hong > Ins > Hai > Pi); Na (Pi > Hai > Ins > Hong); Fe (Ins > Hong > Pi > Hai).
【Conclusion】 The correlations between the different mineral elements of raisins and each mineral element of the soil were more complex, with different degrees of positive and negative correlations.
