摘要
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。
The effect of lanthanum (La) accumulation on availability of soil nutrients in red soil was studied through indoor soil culture and pot culture experiments. The results showed that La accumulation decreased the content of soil available nitrogen and phosphorus, that there was significant negative correlation between the concentration of La and soil available nitrogen and phosphorus, and that La had no significant effect on soil available potassium.
