Abstract: The paper aims to study different fertilization mode on yield and growth and development of maize, explore the best mechanization fertilization mode and provide the basis for the whole course mechanization pro?duction of maize. Experiments were conducted in different ecological zones in Henan for two consecutive years with‘Zhengdan958’as the material, and four fertilization modes were set to compare yield and growth and de?velopment of summer maize. The results showed that, compared to CK, the yield and nitrogen use efficiency of twice mechanization fertilization mode increased 8.8% and the kernel number per spike increased 5.9%, the 1000-kernel weight increased 1.2%, the plant dry matter increased 9.8% and ear characters increased to a cer?tain extant. The yield and yield components, dry matter, ear characters and nitrogen use efficiency of twice mechanization fertilization mode were similar to that of empirical mode. The twice mechanization fertilization mode was an ideal field mechanization fertilization model.
