锰素营养可以提高甜菜的含糖量。据试验,施用锰肥可以使甜菜含糖量提高0.8—1.5%,对防止甜菜黄斑病也有重要作用。锰素是组成叶绿体的成分之一。当植物体锰素不足时,叶绿素含量会降低,叶片就会出现失绿现象。锰素也是植物体内许多酶的成分,而且能提高多种酶的活性。由于锰本身原子价可以改变(m_n~+(2)m_n~(+7)),所以,锰对植 Manganese nutrition can improve the sugar content of sugar beet. According to the test, the application of manganese fertilizer can increase the sugar content of sugar beet 0.8-1.5%, to prevent Beet Disease also has an important role. Manganese is one of the components that make up the chloroplast. When plants lack of manganese, chlorophyll content will be reduced, the leaves will appear green phenomenon. Manganese is also a component of many enzymes in plants and enhances the activity of many enzymes. Since the atomic valence of manganese itself can be changed (m_n ~ + (2) m_n ~ (+7)),
