红壤施用不同有机酸解铝毒效果的比较

Role of Enveloped Organic Acids in De toxification of Aluminum in Red Soil

以黑麦草为供试植物,进行了施用柠檬酸和草酸解除红壤铝毒的生物盆栽试验。结果表明,施用包膜有机酸比非包膜有机酸具有更好的解铝毒效果,其效果随施用浓度的增加而显著提高,且包膜柠檬酸比包膜草酸的效果更佳。

Detoxifying aluminumtoxicity by a pplication of citric and oxalic acid was explored with ryegrass cultivation in red soil.The results showed that:(1)the effect of enveloped organic acid s was better than un -enveloped organ ic acids;(2)the effect of en-veloped organic acids was increased extremely with an increasing level of enveloped organic acids;(3)the effect of enveloped citric acid was comparatively better than o xalic acid.
