在植物中,微量元素(硼、锰、钼、锌、铜等)的含量是微不足道的,但是对植物的新陈代谢和酶的活性却影响很大。微量元素的作用表现在提高合成过程(光合作用、蛋白质的形成)的强度,改善原生质的胶体性质以及调节植物的水分状况,从而促进植物生长和提高对不良环境条件的抵抗力。锰、硼和铜参与光合作用和呼吸作用,调节糖代谢和磷的复杂有机物的合成。锌是形成生长激素和叶绿素所必需的物质,钼是参与氮 Trace amounts of trace elements (boron, manganese, molybdenum, zinc, copper, etc.) in plants are negligible, but have a major impact on plant metabolism and enzyme activity. The role of trace elements in enhancing the synthesis process (photosynthesis, the formation of protein) strength, improve the colloidal nature of protoplasm and regulate plant water status, thereby promoting plant growth and improve the resistance to adverse environmental conditions. Manganese, boron and copper are involved in photosynthesis and respiration and regulate the synthesis of complex carbohydrates and phosphorus in organic matter. Zinc is required for the formation of growth hormone and chlorophyll, and molybdenum is involved in nitrogen
