邻苯二甲酸

Effects of 1 2-benzenedicarboxylic acid dibutyl phthalate and diphenylamine on mineral elements absorption of young tomato root system were studied in this paper.

以番茄为试材，研究了邻苯二甲酸、邻苯二甲酸二丁酯和二苯胺3种化感物质对番茄幼苗根系吸收矿质元素的影响。

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.

随着邻苯二甲酸浓度的增加，其对番茄幼苗根系吸收N、P、K的抑制作用增强；低浓度的邻苯二甲酸二丁酯可以促进番茄幼苗根系对N的吸收，抑制对P、K的吸收，高浓度时对N、P、K的吸收均起抑制作用；低浓度的二苯胺可以促进番茄幼苗根系对N、K的吸收，抑制对P的吸收。

In the paper the deterrent content and the concentration of diphenylamine dibuty l phthalate and centralite Ⅱ in finished product manufactured by two different methods were analyzed by high performance liquid chromatography, which can provi dereference for adjusting the technology of the propellant manufacture.
