摘 要:盆栽试验研究不同措施对土壤-植物系统植物地上部产量及F含量的影响结果表明,F对黑麦草发芽有抑制作用,干旱下植物易受F中毒,黑麦草地上部鲜物质量、干物质量及F含量在2种土壤(黄壤、石灰土)间呈相同变化趋势,试验所选4种物质不利于黑麦草干物质量的积累。硅钙肥、石灰对黑麦草F含量均为负效应,有利于降低F含量,粉煤灰对2种土壤黑麦草F含量均为正效应,风化煤对黄壤黑麦草F含量表现为正效应,而对石灰土黑麦草F含量则表现为负效应;硅钙肥和风化煤对2种土壤黑麦草F含量均表现为负交互作用,而石灰和粉煤灰对黑麦草F含量均为正交互作用。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.
