| Abstract: | Using 15N labelled fertilizers,the influence of the application atdifferent growth stages on the nitrogen absorption,organ formation andyield of winter wheat was studied in the Beijing district in the years of1979 through 1981.The fertilizers applied included ammonium sulphate,600 kg per hectare,and urea in an equivalent amount of nitrogen.Eitherone or the other fertilizer was applied only once for each treatment,butat different growth stages,including an application before sowing.The results indicated t... |
