%X The field plot experiments of applying two kinds of controlled release nitrogen fertilizer (CRNF) on winter wheat were conducted, showing that the winter wheat yield and its components are improved, and the nitrogen use efficiency is elevated by a range from 2% to 6% under different irrigation conditions and same quantity of nitrogen. The N of two kinds of CRNF is not only absorbed by the winter wheat but also remains more than urea in cultivate layer at harvest stage. From the economic analyses, the net gain of wheat by CRNF treatment can be increased by 1082 yuan/hm2, more than that by urea treatment under an appropriate irrigation condition.
