我国目前推广或将要应用的微肥有:硼肥、钼肥、锌肥、铜肥、锰肥、铁肥。它们在农作物、林木、牧草、果树、蔬菜上施用,均有相互不能代替的作用。针对缺素土壤和敏感植物施用微肥,增产效果十分显著。微肥分类多种多样。归纳起来有按所含营养元素划分的,也有按养分组成划分的,还有几种按化合物类型划分的。前面提到的目前推广应用较多的硼肥、钼肥、锌肥等就是按所含营养元素划分的,这是大家极其熟悉的一种分类。就这些元素的离子状态来说,硼和钼常为阴离子,而锌、锰、铜、铁、钴等元素则为阳离子。
Micronutrients currently being promoted or to be applied in our country include: boron fertilizer, molybdenum fertilizer, zinc fertilizer, copper fertilizer, manganese fertilizer and iron fertilizer. They are used on crops, trees, pastures, fruit trees and vegetables, and can not replace each other. For the lack of soil and sensitive to the application of micronutrients, the yield is very significant. A variety of fertilizer categories. Summed up according to the nutritional elements contained, but also divided according to nutrient composition, there are several types of compounds by the division. Mentioned above, the current promotion of more boron fertilizer, molybdenum fertilizer, zinc fertilizer is divided by the contained nutrients, which is extremely familiar to everyone of a classification. In terms of the ionic state of these elements, boron and molybdenum are often anions, while elements such as zinc, manganese, copper, iron and cobalt are cationic.
