艾佐迈对葡萄叶片中10种必需矿质元素和15种稀土元素的影响

Effects of Azomite application on 10 essential mineral elements and 15 rare earth elements in vine leaves

近年来,艾佐迈(Azomite)作为一种矿质肥料被广泛应用于果树生产中。本文以赤霞珠、蛇龙珠、贵人香3个酿酒葡萄品种为试材,应用电热板消解-电感耦合等离子体质谱(ICP-MS)技术分析施用艾佐迈对葡萄成熟叶片中10种必需矿质元素与15种稀土元素的影响。结果表明,未施肥的3个品种的叶片中必需矿质元素B、Mo、Mg、K、Mn、Ca、Ni、Cu、Zn均有明显差异,但稀土元素差异不明显;施用艾佐迈肥料可不同程度地提高叶片中必需矿质元素和稀土元素的含量;品种间的比较分析显示,3个葡萄品种对不同必需矿质元素的吸收能力存在着明显差异,但对稀土元素的吸收差异并不明显。

Azomite, as a mineral fertilizer, was widely applied to fruit production in recent years. The effects of Azomite application on 10 plant essential mineral elements and 15 rare earth elements in vine leaves of three wine grape varieties （Cabernet Sauvignon, Cabernet Gernischt and Italian Riesling） were investigated through the technique of inductively coupled plasma mass spectrometry （ICP-MS） with electric heating board digestion in this study. The results showed that there was significant difference in the levels of essential elements including B, Mo, Mg, K, Mn, Ca, Ni, Cu and Zn, but no visible difference in 15 rare earth elements among three wine grape varieties, which were not treated with Azomite. Azomite application could increase the levels of the essential mineral elements and rare earth elements in vine leaves to different extents. The comparative analysis indicated that there was great difference in absorbing abilities to various essential mineral elements among these varieties, but no significant difference to rare earth elements. This work would provide a theoretic basis for the application of Azomite and the management of vineyard fertilization.
