Title: Effects of Different Nitrogen Forms on Soil Nitrogen Supplying Capacity and Nitrogen Content of Wheat Plant and Grain
Abstract: Field experiment was conducted to investigate the effects of different nitrogen forms on soil nitrogen supplying capacity and plant nitrogen content in 2006-2007 growing season.The amount of nitrogen was 240 kg/ha with three nitrogen forms: NO-3-N(NaNO3),NH+4-N(NH4HCO3) and CONH2-N(urea),respectively.Result indicated that the soil total nitrogen and available nitrogen were the highest with NO-3-N treatment.But the activity of nitrate reducase in leaves and the nitrogen content of different organs in plant before mature with NH-2-N treatment were higher than the other treatments.The grain protein content and nitrogen utilization efficiency of NH2-N treatment were the highest in the three treatments.It was concluded that the amide nitrogen was suitable for strong gluten wheat.
