摘　　要：养殖场沼气工程排出的沼液浇灌萝卜的田间试验表明,沼液不同灌溉量处理与常规施用化肥的对照处理相比,对土壤质量有所改善,土壤的氮磷水平变化不大,各处理对萝卜产量基本无影响,用沼液浇灌替代部分化肥可明显降低萝卜中硝酸盐的含量,合理进行沼液农田灌溉不仅可以减轻规模养殖场污水处理的排放压力,而且可以减少化肥施用量,降低生产成本。Influence of biogas slurry of different concentrations on the soil environment and quahty of radish were studied through experiments of biogas slurry as supply fertilizer with water at different ratio. Results showed that under equal to nitrogen＇s condition the biogas slurry irrigating were helpful to improve quality of radish, had promoted soil quality compared with general chemical fertilizer, and decreased chemical fertilizer quantity.
