【Abstract】 The seed samples of wheat,sorghum and soybean were irradiated by using Sames Co.Model "S" ion accelerator with a flux of 10⁹ n·cm^-2.Gamma- spectra were measured by using DGL 20F Ge （Li） detector with a 4096channal analyzer Tridac-C.The samples and standards were treated alternately in the sequence of 10-minute irradiation,1-minute dacay cooling and 10-minute counting.The N,P and K contents were determined simultaneously,while the relative precisoin was～±3% for N and～±6% for P and K.更多还原
