Field experiments were conducted to study the effects of different dosages coated controlled release urea (PCU60, 60 d release duration) combined with conventional urea (U) used as basal on the winter wheat grain yield, nitrogen (N) recovery rate, and soil NO3- -N content, etc. Five treatments were installed, i.e., U (CK), 10% PCU60+90% U (PU1), 20% PCU60+80% U (PU2), 30% PCU60+70% U (PU3), and 40% PCU60+60% U (PU4). In the meantime, a comparative analysis was also carried out on the PCU60 N release characteristics under field condition and in 25 "C static water. At the same N dosage, all the test indices in treatment PU4 were significantly higher, with the grain yield, N recovery rate, total N accumulation amount, total tiller number and aboveground biomass at ripening stage, and economic benefit increased by 5.6%, 14.6%, 7.2%, 2.6%, 7.5%, and 984.3 yuan x hm(-2), respectively, compared with those in treatment U. The accumulation amount of NO3- -N in 0-100 cm soil layer in all treatments ranged in 39.70-49.93 kg x hm-2, and was the lowest (39.70 kg x hm(-2)) in treatment PU4. The N release pattern of PCU60 under field condition better fitted the N absorption characteristics of winter wheat.
