Current situation,problems and countermeasures of resource utilization of agricultural waste:a case study of Dongliang modern agriculture and animal husbandry circular economy industrial park in Yutai County
The common problems of low comprehensive utilization rate of crop straw,mushroom residue,and large production of animal manure,and unscientific treatment process in Yutai County which is likely to cause secondary environmental pollution,restricted the high-quality and sustainable development of modern agriculture.The aerobic fermentation process of animal manure,crop straw,and mushroom residue with high water content was carried out in Dongliang modern agriculture and animal husbandry circular economy industrial park in Yutai County.Combined with the actual situation of the park,the treatment modes of the three-grid manure treatment system,and heterotopic fermentation bed suitable for the development of the park were formed.The operation modes of"animal manure+straw+mushroom residue+biological agent"aerobic fermentation recycling for edible fungi farms and large-scale pig farms were explored.The development,demonstration,and promotion of the organic waste aerobic fermentation-solid fertilizer production-returning to field were carried out.Those would promote the localized,fertilization,and recycling of organic waste,improve soil fertility in farmland,which were conducive to rural revitalization and beautiful rural construction,promoting the high-quality development of modern green ecological agriculture in rural areas.
