通过室内培养和盆栽试验 ,研究了镧积累对红壤有效养分的影响。结果表明 ,镧积累降低了土壤有效氮、有效磷含量 ,有效氮、有效磷含量与镧浓度呈显著的负相关 ,镧对土壤有效钾的影响不明显。
Through indoor culture and pot experiment, the effect of lanthanum accumulation on available nutrients in red soil was studied. The results showed that the accumulation of lanthanum reduced the content of soil available nitrogen, the content of available phosphorus, available nitrogen and available phosphorus were negatively correlated with the concentration of lanthanum. The effect of lanthanum on soil available potassium was insignificant.
