宁夏回族自治区养殖粪污资源化利用现状调查与分析

Investigation and Analysis of the Utilization of Manure Resources in Ningxia Hui Autonomous Region

畜禽粪污资源化利用,是农村生态环境保护工作的重点和难点,对于改善农村生态环境质量、提高农业绿色发展水平、促进农产品增产提质具有重要意义。本文为进一步了解宁夏回族自治区(简称“宁夏”)畜禽粪污资源化利用现状,在宁夏银川市、石嘴山市、吴忠市、中卫市、固原市5市,对四大产业主导区畜禽养殖产业基本情况、全区及各市不同类型和规模的畜禽养殖粪污资源化利用现状及问题、不同养殖类型和规模的资源化主推技术及典型案例等情况进行了实地调研。结果表明:2020年,宁夏畜禽存栏总量2046.0万头(只),其中,奶牛57.4万头、肉牛120.7万头、羊596.1万只、生猪90.0万头、家禽1181.8万只。畜禽粪污产生量3025.3万吨,全区粪污资源化利用总量为2961.6万吨,综合利用率达到97.9%,规模养殖场设施配套率达99.0%,该地区畜禽粪污综合利用主要途径有肥料化利用、能源化利用、清洁再生回用等。
