摘　　要：以上海郊区10.67万hm2水稻田为研究区域,利用GPS定位网格采集土壤样品4087个,建立了12个水稻高产示范基地。应用ASI土壤快速测定方法开展了水稻磷钾肥推荐试验。结果表明:水稻磷钾肥推荐施肥平均产量9034.5kg·hm-2比常规施肥8236.5kg·hm-2,增产798.0kg·hm-2,增幅达9.69%,增收1436.4元·hm-2,经济效益显著。研究成果为示范推广精准农业技术提供了科学依据。In the rice paddy research area which has 106 700 hm2 in Shanghai suburbia, founded 12 rice high yield demonstration bases, and gathered 4087 soil samples by GPS Receiver. The phosphorus（P） and potassium（K） recommended fertilization experimentation was arranged by the method of Agro Services International Ine（ASI） rapidly testing soil nutrients. The examination results indicated that the yield of recommended fertilization treatment and general fertilization treatment were 9034.5 kg·hm^-2 and 8236.5kg·hm^-2 respectively, and the former increased production by 798.0kg·hm^-2 or 9.69%, increased earning by 1436.4 Yuan·hm^-2 than the latter. Economy benefit was in evidence. The research fruit offers science according to demonstrate and popularize precision agrieuhure technology.
