Effect of different measures on the overground yield and fluorine content of plant in soil-plant system
Chinese Journal of Eco-agriculture(2006)
摘要
Potted plant experiment was carried out to study the overground yield and fluorine content of plant in soil-plant system under different measures. The results show that fluorine has a depressing effect on the spring of rye grass,it is(easy) to get fluorosis when it meets drought;green weight,dry weight and fluorine content of rye grass overground have the same trend between yellow soil and calcareous soil;the four materials selected do no good to the accumulation of the dry weight of rye grass;Si-Ca fertilizer and lime have negative effects on the fluorine content of rye grass,and do good to declining the fluorine content,coal fly ash has(positive) effect,saprolite of coal has positive effect on yellow soil,and(negative) effect on calcareous soil.Furthermore,Si-Ca fertilizer and saprolite of coal have a negative common effect in the two kinds of soil,while lime and coal fly ash have a positive common effect.
