摘要
农村发展沼气不仅可以开辟能源利用,而且其沼气发酵残留物可作为有机肥肥源,提高土壤肥力,改良土壤,促进农业良性循环。沼肥不仅具有良好的保肥性能,而且对多种作物具有显著的增产效果,尤其是在作物品质方面效果更佳。本文在查阅已有研究资料基础上,就沼肥用于蔬菜生产时对蔬菜产量、品质的影响以及沼肥使用存在的问题等方面进行了简要论述。
Developing biogas in countryside can exploit energy resources, and its fermentation residue can be used as organic fertilizer, which can not only improve soil fertilization, but also improve crop yield and quality. This paper summarizes recent sdudies on utilization of biogas fermentation residue improving vegetable yield and quality. And existing problems and developing propects in the future are also discussed.
