摘　　要：基于3S技术,研究了分散经营模式下的土壤养分精准管理,提出了适合分散经营模式下土壤养分管理系统的构建方法,详细介绍了GPS定位取样、数据库建立和专家系统构建等关键环节,并在水稻和西甜瓜的田间试验中验证了该系统的应用效果。结果表明:水稻产量较当地习惯施肥增产10%以上,增收585～870元(人民币,下同)/hm^2;西甜瓜产量较当地习惯施肥增产14.67%～27.09%,增收10 500～21 000元/hm^2。The precision management of soil nutrients in the decentralized management was studied by means of 3S technology,a method of building soil nutrients management system was proposed,and such key links as GPS-located sampling,database establishment and experts system construction were described in detail. The application of this system to field experiments of rice and melon showed that the rice yield increased by more than 10% over that in the local conventional fertilization and its in- come increased by 585 - 870 yuan RMB/hm2 ; The melon yield increased by 14.67% - 27.09% over that in the local conventional fertilization and its income increased by 10 500 - 21 000 yuan RMB/hm2.
