微量元素的缺乏,在一些地区已经成为农作物增产的瓶颈。但在另外一些地区,微量元素比例失调,个别元素严重超标,又导致农产品品质劣化和减产。因此,微量元素肥的设计和应用应该是一项十分慎重的 The lack of trace elements has become a bottleneck in the increase of crops in some areas. However, in other areas, the proportion of trace elements is imbalanced and the individual elements seriously exceed the standard, which in turn leads to the deterioration of the quality of agricultural products and the reduction of output.
