土壤硒的丰缺与人类和动物的健康密切相关，依据李家熙的土壤硒含量划分标准，石头河地区存在中硒土壤（0．2～0．4×10-6）和富硒土壤（＞0．4×10-6）。小麦籽实分析均为富硒小麦，与富硒土壤关系密切。硒形态分析表明土壤中硒的强/弱有机结合态、水溶态、残渣态、铁锰结合态、碳酸盐结合态含量变化均为：水稻土＞水系沉积物＞褐土。硒的全量及形态含量受pH值影响较大，在酸性土壤中施加一定量的CaCO3，可提高土壤的pH值，增加硒的溶解度，有利于提高植物对土壤硒的吸收。

The abundance and deficiency of soil selenium is closely related to the health of human being and animals.According to the classification definition standard of soil selenium amount put forward by Li Jiaxi,it is confirmed that there exist selenium-rich soil (0.2~0.4×10-6 ) and selenium-moderate soil (>0.4×10-6 ) in Shitou River area.The analytical results of wheat seeds show that the Se a-mount is up to the standard of selenium-rich wheat.A study of the modality of Se in the soil shows that the Se content change of stream sediments and cinnamon soil,water soluble state,residue,Fe-Mn oxides and carbonate-bound selenium is in order of paddy soil>stream sediment >cinnamon soil.Soil pH value has a great impact on the amount of ion exchange state selenium,and the addition of a certain mount of CaCO3 can improve pH value in acid soil and is in favor of increasing the solubility of selenium.
