- Abstract:
- The field experiment was conducted to study the different contents of dibutyl phthalate(DBP),ethylhexyl phthalate(DEHP),Pb,and Cd in both soil and the plants in soybean growth periods with different residual amount of mulching plastic film in salinized meadow soil and meadow albic soil.According to the experiment,the contents of DBP and DEHP are higher with high residual mulching film compared with that of lower treatment,and the difference is obvious;the DEHP was not discovered in the plants.As for the contents of DEHP and DBP in comparison soil,they decline obviously as the plants grow,while they show growth from 1 time to 3 times residual amount of mulching plastic film.Analysis DBP and DEHP contents was made in different periods which are obvious in the result.The contents of Pb and Cd are higher with high residual mulching film compared with that of lower treatment,and the difference is obvious.No obvious change in the contents of Pb and Cd was detected in different periods under the same treatment;and the difference of contents is not obvious in both the plants and the seeds between 1 time and 3 times residual amount of mulching plastic film.Yet the contents in the seeds are lower than that in the plants.The same result was obtained in both salinized meadow soil and meadow albic soil.
