No matter when nitrogen, with nitrogen application (75 kg - hm-2 - kg -255 hm-2) increased the growth period of 0 - 300 cm soil water contentincreased, leaf nitrogen accumulation in mature stage decreased significantly after the first increase, stem and stem nitrogen accumulationincreased significantly at first and then decreased, and cob glume the nitrogen accumulation amount is reduced, and the accumulation of grainN content increased significantly, while the nitrogen translocation rate and post anthesis nitrogen accumulation increased significantly,decreased first and then increased pre anthesis nitrogen contributionafter anthesis nitrogen accumulation with increased first and then decreased, nitrogen absorption efficiency, nitrogen partial productivitydecreased significantly, while the nitrogen harvest index increased significantly. The fallow period of nitrogen fertilizer with nitrogen (75 - 255kg - hm-2) the increase of various organs nitrogen transfer and transfer rate were increased significantly, panicle number, grain weight and yield increased, grain number per ear decreased first and then increased. The fallow period of nitrogen than before sowing nitrogen can increase thenitrogen of mature leaf, spike, glume and grain and shoot accumulation,can significantly improve the efficiency of nitrogen absorption and nitrogen partial productivity and nitrogen harvest index, spike number,1000 grain weight and yield. The amount of nitrogen was 255 kg - hm-2,fallow n before sowing with nitrogen can improve the leaf, spike, glume and vegetative organs of nitrogen transfer and transport rate increasedbefore anthesis and post anthesis nitrogen translocation amount ofnitrogen accumulation and its contribution rate. The best effect under the experimental conditions in fallow tillage fertilizer 255 kg - hm-2, the yield reached 6381.80 kg - hm-2.
