Study on the fluorine content of soil-plant-water around chemical factory of phosphorus industry and the soil capacity of fluorine adsorption

WAN Hong you, LI Cheng hou(Department of Agronomy,Agricultural College,Guizhou University, Guiyang 550025,China)  
In this experiment, the samples of soil,plant and water in the same line from south to north around the chemical factory of phosphorus industry were gathered. The fluorine contents were determined, the adsorption and desorption experiment in the same temperature of soil were carried out. It shows that the chemical factory of phosphorus industry can cause fluorine pollution, water soluble fluorine,plant fluorine and water fluorine near are higher than that away from the factory, yellow earth has a very high total fluorine and a relatively low water soluble fluorine, calcareous soil has a high total fluorine and a high water soluble fluorine , so calcareous soil is easy to lead to the fluoris. Yellow soil has a bigger adsorption of fluorine than calcareous soil. Water soluble fluorine has good relationship with plant fluorine and water fluorine,but has no direct relationship with total fluorine.
