The effects of mixed sowing of summer maize seeds and controlled release fertilizers on summer maize yield，nutrition absorption of nitrogen，phosphorus and potassium，economic benefits of fertilization，enzyme activity and soil microorganisms were explored to provide technical support for labor-saving and simplified production of summer maize and reduce fertilizer application and increase the efficiency. A field experiment was conducted with summer maize variety‘Zhengdan 958’. The experiment included four treatments:no nitrogen control，conventional fertilizer application，mixed sowing of seeds and controlled releasefertilizers，and mixed sowing of seeds and controlled release fertilizers with50% rate reduction of nitrogen，phosphorus and potassium. The yield，nutrition absorption of nitrogen，phosphorus andpotassium，leaf enzyme activity and rhizosphere soil microbial function genes of summer maize were investigated. Comparedwith conventional fertilizerapplication，summer maize yield of RCF and RCF50 treatment was increased by7.7%-22.1%，The absorption of nitrogen，phosphorus and potassium by summer maize were increased by0.75%-33.3%，16.3%-27.1%and4.78%-36.5%，respectively. The nitrogen recoveryefficiency，nitrogen agronomicefficiency，nitrogen partial factorproductivity were increased by 20.7%-24.6%，14.1-20.2 kg/kg and 14-74.1 kg/kg，respectively. And the net income perhectare of summer maize(excluding fertilizerinput)was increased by 9.67%-19.6% compared to conventional fertilizerapplication，there was no significant difference of the gene number of nitrification and denitrification microorganisms inrhizospheresoil，nitratereductase，glutaminesynthetase，glutamic acidsynthase，and glutamate dehydrogenase in leaves at silking stage. The contact application of controlled release fertilizer with summer maize seed achieved yield increase andincome increase，improved nitrogen，phosphorus，and potassium nutrient absorption and nitrogen fertilizer utilizationefficiency，and reduced environmental pollution risks.
