大气氟污染对土壤及冬小麦生长发育的影响

Effect of Fluorine Pollution of Atmosphere on Soil and Winter Wheat Growth

对郑州市某中型铝厂附近的大气、土壤含氟量及对小麦各器官发育的影响进行了研究。结果表明：（１）大气、土壤含氟量与距污染源的距离呈负相关。（２）冬小麦各器官含氟量与距污染源的距离呈负相关；各产量性状及产量因距离不同而受到不同的影响。以此作者将污染区划分为重度污染区、中度污染区、轻度污染区。

This paper deals with the effects of fluorine pollution of soil and atmosphere on winter wheat growth.The study shows that (1) fluorine content in the soil and atmosphere was inversely corrrelated with its distance from the pollutin source;(2)fluorine content in various organs of winter wheat was inversely correlated with its distance from the pollution source,and the characteristic of yield and winter wheat yield were affected with the distance.Based on the analysis,the pollution areas of the study site can be divided into the following: seriously polluted areas, mediumly polluted areas,slightly-polluted areas,relatively-clean areas and clean areas.
