硼、锌、锰等微量元素及稀土元素肥料是植物正常生长发育需要很少而又不可缺少的营养物质。这些微量和超微量元素作为生物体中酶或辅酶的组成成分,参与生物机能的活动,如叶绿素、生长素的合成,能增强作物的呼吸作用、光合作用和氧化还原过程,对改善碳水化合物的合成与运输具有多方面的生理作用。因此,这些元素的供给状况,同样地影响作物的生 Boron, zinc, manganese and other trace elements and rare earth fertilizer is a natural plant growth and development needs little but indispensable nutrients. These trace and ultra-trace elements, as components of enzymes or coenzymes in organisms, are involved in biological functions such as chlorophyll and auxin synthesis, which enhance the respiration, photosynthesis and redox processes of crops, Synthesis and transport have many physiological effects. As a result, the availability of these elements also affects crop health
