Title: Effects of Slow-release Nitrogen Fertilizers on Yield of Maize and Rice,Nitrogen Use Efficiency and Inorganic N Residue
Abstract: Three nitrogen fertilizers(conventional urea,slow release urea 1 and slow release urea 2) were tested under field experimentation during two years to investigate the differences of the yield of maize and rice,N use efficiency and inorganic N residue.Results showed that slow-release N could increase maize and rice yield,and N use efficiency significantly.Compared with conventional urea,the yield of maize and rice increased by 10.35% and 8.00% and the N use efficiency increased by 14.01% and 7.41% with experimental fertilizer 1,and the yield increased by 10.12% and 12.55% and the N use efficiency increased by 5.87% and 4.79% with experimental fertilizer 2.The fertilizer 2 had a better effect in paddy field.Both of two kinds of slow release urea showed the same effect in dry land.
