摘要
当前畜禽粪污是造成农业面源污染的重要原因,其中畜禽粪便中的氮磷钾资源含量占同期化肥消耗量的比例较高,具备较好代替化肥的潜力。结合现状,种养结合是解决畜禽粪便污染问题的理想方案,通过全量还田和堆肥还田结合的处理方式,能加快推进畜禽养殖废弃物处理和资源化,有效治理农业面源污染和改善人居环境。
At present,livestock manure is an important cause of agricultural non-point source pollution.Nitrogen,phosphorus and potassium resources in livestock manure account for a higher proportion of fertilizer consumption in the same period,and it has better potential to replace fertilizer.Combining current situation,planting and breeding is an ideal solution to solve problem of livestock manure pollution.Through a combination of full-scale returning and composting,it can accelerate treatment and recycling of livestock and poultry farming waste,and effectively control agricultural non-point source pollution.And it also could improve living environment.
