[目的]研究乌鲁木齐市再生水用于农业灌溉的可行性。[方法]以小白菜为研究对象,分别用清水对照、浓度50%的再生水和浓度100%的再生水浇灌,测定小白菜内部微生物菌群数。[结果]浓度50%的再生水增加了小白菜68.94%的湿重,但随着外源微生物内化程度的加深,小白菜体内菌群总数和大肠菌群数都在0.05水平显著高于其他。[结论]再生水在提高小白菜质量的同时能增加其内部细菌含量,不宜用于小白菜等可食用性作物的浇灌。若在污水处理时加强消毒措施则可以解决该问题。
[Objective] The research aimed to study the feasibility of using reclaimed water from Urumqi for agricultural irrigation. [Method] With Chinese cabbage as the research object, the number of microflora in cabbage was determined by using fresh water, 50% reclaimed water and 100% reclaimed water respectively. [Result] The concentration of reclaimed water at 50% increased the wet weight of Chinese cabbage by 68.94%. However, with the deepening of the internalization of exogenous microorganisms, the total number of bacteria and coliforms in Chinese cabbage at 0.05 level was significantly higher than the others. [Conclusion] Reclaimed water can increase the content of bacteria in cabbage while improving the quality of cabbage, and should not be used for irrigating edible crops such as cabbage. If the disinfection measures in the sewage treatment can solve the problem.
