摘要: 通过规模养殖场沼液灌溉青菜的田间试验表明,不同沼液灌溉量处理与常规施用化肥的对照处理相比,对土壤质量基本无影响,等氮条件下用沼液可替代或减少氮肥使用量,对青菜产量基本无影响。合理施用沼液进行农田灌溉不仅可以减轻规模养殖场污水处理的排放压力,还可以减少化肥施用量,提高青菜的品质。

Abstract: Different concentrations of biogas slurry were irrigated in scale raising farms to investigate their effects on the soil environment and quality of Brassica chinensis. Compared with the normal chemical fertilizer (CK), different irrigation amounts of biogas slurry showed no effect on the soil quality. Under equal nitrogen condition, the biogas slurry used as an organic fertilizer with rich nutrient contents instead of nitrogen fertilizer, were helpful to improve quality of Brassica chinensis. Application of biogas slurry with proper dose could not only decrease the wastewater disposal in scale raising farms, but also decrease the application of chemical fertilizer and improve the quality of Brassica chinensis.
