摘要
通过盆栽试验研究猪场沼液对芥菜产量和品质的影响效应,旨在为其资源化利用提供科学依据。结果表明:与对照相比,施用沼液能够显著提高芥菜根系活力,增加产量和生物量,以100%原沼液的增产效果最好,地上部产量增加21.5%,生物量增加22.1%;施用沼液具有改善芥菜品质的效果,与对照相比,50%处理后沼液可提高芥菜可溶性蛋白和可溶性糖含量,分别增加25.1%和27.1%,但维生素C含量差异不显著。因此,合理施用沼液进行农灌不仅可以减轻养殖场处理后污水的排放压力,还可以减少化肥施用量,提高叶菜品质。
A pot experiment planted with mustard was conducted for investigating the impact of piggery biogas slurry（PBS） on yield and quality.The results showed that the application of PBS could increase the biomass,yield,root activity and quality of mustard.Sample treated with Y100% had the best yield and biomass（21.5% and 22.1% increase respectively） compared with control.Application of PBS could improve the soluble protein and the soluble sugar except Vc content.Sample of T50% had the highest soluble sugar and soluble protein content,with 27.1% and 25.1% increase compared with control.Application of PBS with proper dose and method could not only decrease the wastewater disposal in scale raising farms,but also decrease the application of chemical fertilizer and improve the quality of leafy vegetables.
