硼锌锰等微量元素是植物的必需营养元素。虽然动物、植物有机体对它们的需要数量很少。但对动物,植物有机体生命活动过程起了重要作用,它是酶或辅酶的组成并参与植物体内物质代谢过程。土壤中硼锌锰含量供给不足或过量时,将会引起动植物生理生化功能的失调、生长和发育受阻,并会诱发出特殊病害,影响农作物产量和品质。因此了解京郊土壤中硎锌锰有效含量的分布与区划,有助于施用不同的微量元素肥料,对农作
Trace elements such as boron, zinc and manganese are essential nutrient elements of plants. Although animals, plant organisms require only a small amount of them. However, it plays an important role in the life process of animals and plant organisms. It is the composition of enzymes or coenzymes and is involved in the process of material metabolism in plants. When the content of boron, zinc and manganese in the soil is insufficient or excessive, the imbalance of physiological and biochemical functions of plants and animals, the growth and development will be hindered, and special diseases will be induced and the yield and quality of crops will be affected. Therefore, understanding the distribution and zoning of Zinc and Manganese effective content in the soil in the suburbs of Beijing, it is helpful to apply different trace element fertilizers,
