摘　　要：利用安徽省太湖县和江苏省射阳县土肥站数据库系统中2 102份农户化肥施用数据,通过描述性统计分析方法,讨论了在不同作物的种植过程中,采用或者未采用测土配方施肥技术的农户在化肥投入强度、化肥投入结构及其所对应的经济效益等方面的差异。结果表明:采用测土配方施肥技术农户的化肥施用强度明显低于未采用该技术的农户,而且化肥施用结构更优,表明测土配方施肥技术具有较好的"降氮"、"降磷"效应。另外,虽然采用测土配方施肥技术并不能明显降低化肥投入成本,但由于其技术采用带来化肥施用结构的优化能够有效提高化肥利用效率,有利于提高农产品产量并增加农业经营效益。Based on 2102 survey data of fertilizer application collected in Sheyang county,Jiangsu province,and Taihu county,Anhui province,the disparities in fertilizer input density and formula,and the effects on the in come of farmers who adopt the soil testing for formulated fertilization technology or not were analyzed using descriptive statistical method.The farmers who adopt the technology of soil testing for formulated fertilization applied the fertilizer in less density and better formula,indicating that the technology is effective on nitrogen and phosphorus application reduction.Although the use of the technology does not significantly reduce the fertilizer input costs,it brings the optimization and efficiency improvement of chemical fertilizer utilization,contributing to improve the yield of agricultural production and increase the operating efficiency of agriculture.
