Field experiments were conducted to study the impact of rejuvenated water irrigation on the quality of tomato
the heavy metal element in fruit and soil. The results showed that
the protein
vitamin C and organic acid contents of tomato are highest under the QG treatment
followed by HG
and are lowest under the ZG
the differences are notable. It is also discovered that the Cr
Cd and Pb contents in the fruit increased with the advance of the irrigation volume of the rejuvenated water
the differences are not distinct. The accumulation of the heavy mental element in the fruit was not founded with the use of rejuvenated water and the data received in the test were far less than the Chinese National Standard. The difference of the heavy mental element contents in the soil was also not distinct and the data were far less than Chinese National soil quality standard either. The rejuvenated water was used in the experiments. The conclusion is that the short-term irrigation using this water only reduced part of the tomato qualities; heavy mental element was cumulated in neither tomato nor soil.
