摘　　要：通过盆栽试验研究红壤施用柠檬酸、草酸和苹果酸三种不同包膜有机酸对不同小麦品种解铝毒的作用。结果表明,红壤上施用包膜有机酸对小麦具有较好的解铝毒效果,增加了小麦产量。三种包膜有机酸中柠檬酸的效果最佳。有机酸解铝毒的效果因小麦品种而异,其中敏感小麦优于抗性小麦。Effect of different coated organic acids (including citric acid, oxalic acid, and malic acid) on detoxification of aluminum of wheat in red soil was studied using pot experiment The results showed that coated organic acids could efficiently alleviate toxicity of aluminum and increase wheat yield significantly Among the three coated organic acids, citric acid was most effective Sensitive varieties of wheat were better than tolerable ones in efficiency of aluminum detoxification
