摘 要：以二苯胺为原料，水和冰醋酸为溶剂，在酸性条件下一步合成二苯基联苯二胺，该方法具有操作简单，原料易得等优点。

The inhibitive effect of 1, 2-benzenedicarboxylic acid on the absorption of N, P and K increased with its concentration rising. Low concentration of dibutyl phthalate increased the absorption of N, but decreased the absorption of P and K. Its high concentration restrained the absorption of N, P and K, while the low concentration of diphenylamine could stimulate the absorption of N and K, but restrain the absorption of P.
