Abstract
The aim of this study was to determine the effect of the combined application of a urease inhibitor (thiophosphric triamide, NBPT) and a nitrification inhibitor (dicyandiamide, DCD) on yield and quality of wheat. By applying labeled urea into an aquic brown soil, a pot experiment with spring wheat as test crop was conducted in the Shenyang Experimental Station of Ecology (CAS). The results showed that 15N-U+NBPT and 15N-U+DCD, the combination of urea with NBPT and DCD (15N-U+NBPT+DCD) could retard the hydrolysis of urea, increase 15N uptake by wheat, reduce the loss of urea-N in soil-wheat system; the yield of wheat in 15N-U+NBPT+DCD treatment increased 27.77%, and the content of protein increased 10.19% in comparison with CK.
