ABSTRACT
A field experiment was conducted to investigate the effects of irrigation with treated wastewater on the nutrient distribution in cucumber and tomato plants and their fruit quality. Irrigation with treated wastewater promoted tomato growth significantly, but had definite inhibition effect on cucumber growth. After the irrigation with treated wastewater, the nitrogen in plants had the characteristics of upward translocation, potassium was easily to be accumulated in cucumber leaf but not accumulated in tomato root, and sodium was mostly accumulated in root but less enriched in leaf, not giving damage to the plants. No significant effects were observed on the distribution of calcium, magnesium, and chlorine in plants. Under the irrigation with treated wastewater, the overall quality of cucumber and tomato fruits was less affected. The nitrate concentration in cucumber and tomato fruits was increased by 5.3% and 32.9%, respectively, but still lower than the state food safety standard of China.
