目前我省农户普遍存在过量施肥这一现象。过量施用化肥会造成土壤板结,农作物减产,对水资源、空气乃至人的身体健康都有一定的危害。判断哪些因素导致了农户存在过量施肥的行为是十分必要的。通过实地调研,汇总数据,运用二元Logistics回归分析方法,从农业保险、购买化肥资金来源渠道、贷款政策等金融支持领域和农户自身特征等方面进行分析,得出对过量施肥产生影响的因素。 At present, farmers in our province are over-fertilized this phenomenon. Excessive application of fertilizers can cause soil compaction, crop yield reduction, and some harm to water resources, air and even human health.
