【摘要】 武平县桃地村属富氟矿型氟中毒病区,该村灌田用水含氟量平均达13.56mg/L,稻田土壤可溶性氟化物含量平均达64.62mg/kg,地瓜田土壤可溶性氟化物含量达27.98mg/kg,分别是解放村相同样品平均含氟量的46、100和9倍。两村生长的稻米平均含氟量相近(P>0.05),桃地村生长的地瓜含氟量明显高于解放村,差异显著(P<0.05)。笔者认为,对氟的富集敏感的植物品种其生长受高氟环境影响,反之则影响不大。更多还原

【Abstract】 In Wu Ping county,Taodi village was a fluonine poisned area of rich-fluorined mine.In this village the average fluorine content in the irragating water was 13.56mg/L,the average dissolvable fluoride content in the soil of the rice field was 64.62mg/L and that in the soil of the field of sweet potatoes was 27.98mg/L.The fluorine content in the above was 46、 100 and 9 times of the same samples in Jiefang village respectively.The average fluorine content in the growing rice in the two villeges were almost the same(P>0.05).But the fluorine content of the growing sweet potatoes in Taodi village was obviously higher than that in Jiefang village,the difference was significant (P<0.05).The growth of the species of the plant which was sensitive to the gathering of fluorine was affected by the rich-fluorined environment,on the controry,it was little affected.更多还原
