摘　　要：对4种代表性"移土培肥"所及的土地利用方式进行研究,结果表明:工程实施对耕地有着显著的影响,坡耕地全N增加191.7%,土壤有机质增加106.2%,全K增加104.7%,园地、梯地脐橙和坡地脐橙平均增产率为11.73%、15.77%和15.37%,坡耕地增产率高达27.90%;在产值方面,梯地脐橙增加6771元/hm2,其次是坡地脐橙5211元/hm2,再次是园地3935元/hm2,最低的是坡耕地,仅为1305元/hm2;水土保持技术对实施移土培肥工程的成败起着非常关键的作用。The authors study on 4 kinds of land use that carried out Fertilizing Project. Result displays that carrying out Fertilizing Project infected remarkably on soil fertility, soil moisture storage, productivity and cash input; on slope farmland, total N increased 191.7%, organic matter increased 106.2%, total K increased 104.7% ; on garden plot and terraced-land planting Citrus sinensis Osbeek, production increased averagely 11.73%, 15.77% and 15.37%, on slope farmland reached 27.90%. About production value, terraced- land planting Citrus sinensis Osbeek increased 6 771 Yuan/hm^2, next it was slope-land planting Citrus sinensis Osbeck 5 211 Yuan/hm^2 , garden plot＇s 3 935 Yuan/hm^2, the lowest was slope farmland, only 1 305 Yuan/hm^2. The key role that decides if Fertilizing Project will be successful or abortive is technique of water and soil conservation.
