在农作物的营养中,除了氮、磷、钾三要素之外,微量元素也起着相当重要的作用。微量元素包括硼、锰、锌、铜、鉄、钼、砷、碘等。这些东西,虽然作物所需要的数量极少,但是缺少了它却又会对植物生长不利。如果用量多了对作物就会有毒害作用。因此微量元素顾名思义以微量来施用它为宜。 In the crop nutrition, in addition to the three elements of nitrogen, phosphorus and potassium, trace elements also play a very important role. Trace elements include boron, manganese, zinc, copper, 鉄, molybdenum, arsenic, iodine and so on. These things, although the crops are in very small quantities, lacking them can adversely affect plant growth. If the amount of more crops will have a toxic effect. Therefore, as the name suggests, trace elements to trace it to apply it is appropriate.
