Abstract：Effects of 1,2-benzenedicarboxylic acid,dibutyl phthalate and diphenylamine on mineral elements absorption of young tomato root system were studied in this paper.The results showed that the absorption of N,P and K were affected by these three allelochemicals.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.Generally,the P absorption was mostly affected by these allelochemicals.
