北京市农户蔬菜投入产出特征调查分析

采用问卷调查和入户访谈相结合的方法,从农户视角对北京市蔬菜投入产出中的劳动力投入、土地投入、水资源投入、种植技术采用、质量安全生产、成本收益等特征进行调查分析。结果表明:北京市蔬菜生产规模普遍较小,以塑料大棚和温室为主;蔬菜种植户对地下水位下降有正确认知,认为灌溉水价较为合理,对灌溉设施可靠性的满意度较高;地膜覆盖、穴盘育苗和高温闷棚在蔬菜种植技术中的采用比例较高;种植户蔬菜质量安全生产的态度较为积极,对产出环节的蔬菜质量安全问题较为重视;雇工费、肥料费和种苗费构成蔬菜生产成本的主要部分。综上,建议推进蔬菜生产规模化发展,健全环境友好型技术推广体系,完善蔬菜质量安全生产管理体系,提倡生产资料合理投入。
