小麦生长发育所必需的元素除氮、磷、钾外,还有铁锌、锰、硼、镁等微量元素。现阶段在小麦生产已出现富氮磷、钾等大宗元素的情况下,产量仍无法提高,说明微量元素缺乏已成小麦超高产的“瓶颈”。所以,在小麦生产中应适时添加微量元素肥料。现将小麦生产中微肥施用方法介绍如下:
Elements necessary for wheat growth and development in addition to nitrogen, phosphorus and potassium, there are iron and zinc, manganese, boron, magnesium and other trace elements. At this stage in the production of wheat has emerged rich in nitrogen and phosphorus, potassium and other major elements of the case, the yield still can not be improved, indicating the lack of trace elements has become a super-high yield of wheat “bottleneck.” Therefore, in the production of wheat should be timely addition of trace element fertilizer. Wheat fertilizer production methods are now introduced as follows:
