摘要

盆栽试验条件下，通过外源添加DBP/DEHP制成0，20，50，100，200 mg/kg的浓度梯度，来研究PAEs对烟草生长的影响及其在土壤—烟草系统的累积特征。结果表明：外源DBP/DEHP的添加对烟草地上部生物量和茎粗无显著影响，烟草株高随外源DBP/DEHP浓度的增加呈现不同的变化趋势，其中黄棕壤烟草株高显著降低，红壤的显著增加，而黄壤的无变化）黄壤根系活力随外源DBP/DEHP浓度先增高后降低，而黄棕壤和红壤的无显著变化。DBP/DEHP浓度对部分烟草抗氧化酶活性有显著影响，而对土壤的脱氢酶和和脲酶活性基本无影响。随外源PAEs浓度的增加，土壤中DBP/DEHP含量均呈现上升的趋势，以黄棕壤DBP含量增加幅度最大，添加200 mg/kg DBP时是CK（外源不添加DBP/DEHP）的3.56倍）黄棕壤和红壤DEHP浓度大幅增加，黄棕壤和红壤添加200 mg/kg DEHP时分别是CK的27.47，27.34倍。相比于CK大多数烟叶中和根系中DBP/DEHP有不同程度的提升。随外源DBP/DEHP浓度的增加，会在一定程度上促进土壤和烟叶DBP/DEHP的积累。

Abstract

Under the pot experiment

DBP/DEHP was added exogenously with the concentrations of 0

100

200 mg/kg respectively to study the effect of PAEs on tobacco growth and its accumulation characteristics in soil-tobacco systems. The results showed that the addition of exogenous DBP/DEHP had no significant effect on the aboveground biomass and stem diameter of tobacco

and the plant height of tobacco showed different trends with the concentration of exogenous DBP/DEHP. The plant height of tobacco remained unchanged in yellow soil

decreased in yellow brown soil

and increased in red soil. The root activity of yellow soil decreased with the increase of exogenous DBP/DEHP concentration

while there was no significant change in yellow brown soil. DBP/DEHP concentration had a significant effect on tobacco antioxidant ezyme activity in some soils

but had no effect on soil denydrogenase and urease activity. With the increase of the concentrations of PAEs

the DBP/DEHP contents in the soil increased

with the highest increase for the DBP contents in the yellow brown soil

which reached its 3.56 times that of CK under the 200 mg/kg DBP. The concentrations of DEHP in yellow brown soil and red soil increased significantly

which were 27.47 times and 27.34 times of CK

respectively when adding 200 mg/kg DEHP. Compared with CK

most tobacco leaves and roots were improved in DBP/DEHP with different degrees. With the increase of the concentration of exogenous DBP/DEHP

the accumulation of DBP/DEHP in soil and tobacco leaves will be promoted to some extent.
