摘　　要：2006—2007年在大石桥地区进行水稻小区施肥试验。试验结果为:确定大石桥地区水稻百公斤产量需氮量为1.63kg、需磷量为1.22kg、需钾量为2.09kg;土壤供氮量为5.485kg/667m2、土壤供磷量为5.891kg/667m2、土壤供钾量为11.044kg/667m2;土壤氮校正系数为0.356、土壤有效磷校正系数为1.696、土壤速效钾校正系数为0.684;肥料利用率氮为35.25%,磷为27%,钾为41.63%。这一系列施肥参数的获得为指导该地区水稻科学施肥提供了可靠的依据。The plot fertilization experiment were done in Dashiqiao area during 2006-2007. The results showed that： 1.63 kg nitrogen, 1.22 kg phosphate, 2.09 kg potassium were needed for 100 kg rice yield; the soil nutrient-supplying amount were 5.485 kg/667 m^2 nitro- gen fertilizer, 5.891 kg/667 m^2 phosphate fertilizer, 11.044 kg/667 m^2 potassium fertilizer; the correction coefficient of soil nitrogen was 0.356, available phosphorus 1.696 and potassium 0.684; the utilization of nitrogen fertilizer was 35.25%, phosphorus 27% and potassium 41.63%. This series of fertilization parameters would provide reliable basis for guiding scientific fertilization in this area.
