| 摘 要： | 本文利用江苏省已推广实施测土配方施肥技术的2个项目县的农户调查数据,通过建立PMP模型,对该技术的经济效果进行了评价。研究结果表明:测土配方施肥技术对增加农户收入的效果明显;该技术的采用会使竞争性作物种植体系中各种作物的播种面积有所调整,但在种植单一作物的情况下则其播种面积不变。

| Abstract: | Using the data about farmer households from two counties in Jiangsu province which have carried out the soil testing technology,this paper evaluates the economic effect of soil testing technology through establishing the Positive Mathematical Programming Model.The result shows that:this technology has significant effects on increasing the income of farmers;if farmers use this technology,sowing areas of competitive crops will change when farmers sowing more than two kinds of crops,but the sowing area will no... |
