Abstract

Abstract:

To investigate the impact of irrigating treated sewage from small town on yield, fruit quality and safety of protected soilless cultured tomato, the effluents from Changping Sewage Treatment Center and a constructed rapid infiltration system were used as irrigation water for tomato plants. The results showed that the yields of tomato irrigated with sewage were slightly lower than that of the control, but there was no difference in the single-fruit weight between all treatments. Qualities of tomato fruits irrigated with the 2 types of sewage were not negatively affected. However, the total zinc content in tomato fruits may exceed the standard requirement in the long run. Based on these results, it can be concluded that reuse of treated sewage from small town as irrigation water for tomato cultured in soilless green house would be feasible and relatively safe. The results provide scientific data support for the efficient recycling of small town sewage in agriculture.

Key words: sewage from small-town, irrigation, tomato, quality

摘要：

为探讨经处理的小城镇污水在保护地无土栽培番茄种植上对番茄产量及果实品质和安全性影响，以北京昌平污水处理中心出水和人工快速渗滤系统处理后的小城镇污水作为番茄灌溉水进行利用，结果表明，用处理后污水进行灌溉，番茄产量略低于清水对照，但不影响番茄单果重。浇灌小城镇生活污水对番茄果实中砷、汞、铅、镉、氟、硝酸盐和亚硝酸盐含量无不良影响，但果实锌含量超标的风险较大。浇灌污水对番茄果实的可溶性固形物、还原糖和维生素C含量无明显的负面影响。因而，将经处理的小城镇生活污水用于浇灌保护地无土栽培番茄的做法是可行的。该研究结果为小城镇生活污水在农业上高效回收利用提供了数据支撑。
