【摘要】 规模养猪场沼液灌溉水稻的田间试验表明,沼液不同灌溉量处理与常规施用化肥的对照相比,对土壤质量基本无影响,用沼液替代(或减少)化肥使用量,对水稻产量基本无影响,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。更多还原

【Abstract】 Influence of biogas slurry of different contents on the soil environment and production of rice were studied through experiments of biogas slurry as supply fertilizer.Under the test conditions the biogas slurry as an organic fertilizer had rich nutrient contents which were helpful to decrease chemical fertilizer quantity,but had no effect on soil quality compared with general chemical fertilizer(CK).更多还原
