Title: Study on Rice Fertilization Parameters in Dashiqiao City
Abstract: 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 m2 nitrogen fertilizer, 5.891 kg/667 m2 phosphate fertilizer, 11.044 kg/667 m2 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%.
