不同沼液灌溉量对西瓜产量及土壤环境的影响

Influence of Biogas Slurry Irrigating on the Soil Environment and Production of Water Melon

对规模养殖场沼液灌溉西瓜进行田间试验,结果表明,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,用大量沼液浇灌替代化肥使用,对西瓜产量基本无影响,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,提高西瓜的品质。

Influence of biogas slurry of different concentrations on the soil environment and production of water melon were studied through experiments of biogas slurry as supply fertilizer with water at different ratio. The results showed that the biogas slurry as an organic fertilizer had rich nutrient contents which were helpful to improve quality of water melon in the test condition,and could decrease chemical fertilizer quantity,but had no affection to soil quality compared with general chemical fertilizer as control.
