铁、锰是植物体生长必需的微量元素。本实验讨论了铁、锰的生物吸收系数 ,介绍了土壤圈中铁、锰元素的生物转化以及它们的生理作用 ,并讨论了铁、锰微肥的利用问题。
Iron and manganese are essential trace elements for plant growth. In this experiment, the biological absorption coefficients of iron and manganese were discussed. The biotransformation of iron and manganese in the soil circle and their physiological effects were also discussed. The utilization of iron and manganese fertilizers was also discussed.
