| In order to explore the effect of several new urea on yield, biomass， nitrogen absorption and economic benefit of corn in Guizhou, and select the most proper one. The test take XiDuSenYu-1 for example, make the N, P2O5, K2O in same level, Compared with ordinary fertilizer, then analysize the maize agronomic traits, yield, biomass, nutrient accumulation and utilization after the several new urea (loss control urea, humic acid urea, shaped net urea, Zinc urea) under field experiment. The Results showed that, compared with common urea treatment, the news were significantly increased the yield , plant biomass, Among them, the disposable urea had the highest yield and biomass, 23.48% and 387.21 g/strain respectively. The loss control urea treatment and loss control urea Single basal application treatment can significantly increase nitrogen, phosphorus and potassium accumulation of corn, the shaped net urea treatment can significantly increase nitrogen, potassium accumulation of corn, the humic acid urea treatment can significantly increase the accumulation of nitrogen, phosphorus. The loss control urea Single basal application treatment had the highest utilization rate, partial productivity, nitrogen absorption efficiency, nitrogen fertilizer and profit, 34.04%, 66.09 kg/kg, 102.09%, 17.08kg/kg and 33.81% respectively. Comprehensive consideration, the control of urea Single basal application is the best choice of corn in guizhou region.
