茶树生育所必需的矿质营养氮、磷、钾、钙、镁、铁、硫称为多量元素,锰、锌、铜、硼、钼等称为微量元素。生产上泛指微量元素系氮、磷、钾三要素以外的营养元素。微量元素在茶树矿质营养中起着特别重要的作用,迄今已从茶叶中检出20余种,计有锰、铝、铁、锌、铜、硫、硼、氯、汞、铋、钡、锶、镍、钨、锡、铅、镉、砷、硅等。微量元 Tea tree fertility necessary for mineral nutrition nitrogen, phosphorus, potassium, calcium, magnesium, iron, sulfur is called the majority of elements, manganese, zinc, copper, boron, molybdenum and other elements called trace elements. Production refers to trace elements in the production of nitrogen, phosphorus and potassium elements other than nutrition. Trace elements play a particularly important role in the mineral nutrition of tea trees. So far, more than 20 kinds of trace elements have been detected in tea, including manganese, aluminum, iron, zinc, copper, sulfur, boron, chlorine, mercury, bismuth, barium and strontium , Nickel, tungsten, tin, lead, cadmium, arsenic, silicon and so on.
