Through 3-year plot experiments in field , the effects of different application rate of Volfertile controlled-release fertilizer on yield and its components of maize were studied under monoseeding conditions . The results showed that the application of controlled -release fertilizer increased the spikes per unit area , grain number of per spike and 1 000-grain weight , so the maize yield was increased , too;the suitable appli-cation rate of controlled-release fertilizer was about 682 kg/hm2 .
