土壤和天然水中某些元素不足或过剩,必将影响植物的生长,并通过植物和饮水影响动物和人体的健康。因而研究某些元素在岩石、土壤、水和植物体中的含量、分布及其地球化学行为,具有重要意义。随着作物产量的提高,一些微量元素的丰缺,在生产上表现日趋明显。例如:我国南方红壤地区,因土壤缺硼引起油菜花而不实;东北三江平原部分白浆土上,小麦花而不孕,经施硼后均获明显增产。
Insufficient or excessive supply of certain elements in soil and natural water will inevitably affect plant growth and affect the health of animals and humans through plants and drinking water. Therefore, it is important to study the content, distribution and geochemical behavior of some elements in rock, soil, water and plant. With the increase of crop yield, the abundance and deficiency of some trace elements have become increasingly evident in production. For example: red soil areas in southern China, due to lack of boron caused by rape blossoms and false; part of the Northeast Sanjiang Plain white soil, wheat and flower infertility, were significantly increased after the application of boron.
