Abstract: Study on senescence of spring maize after anthesis under different cultivation patterns to show the different yield and reveal the quality of patterns, which provided a theoretical basis for defer decrepitude. The ‘Jinshan 27’ was grown under farmer cultivation (NH), high yield (GC) and higher yield (ZGC) condition to study the senescence of Spring Maize after anthesis under different cultivation patterns to assess the indexes of root cap senescence and structure features. The senescence rate of leaf was NH>GC>ZGC at different leaf position, ear leaf senescence rate less than in the third leaf above ear and the third leaf under ear. The activity of SOD and POD of leaves were ZGC>GC>NH, the enzyme activity of ZGC to the peak value than NH and GC late 10 days. MDA content was NH>GC>ZGC, but it differences in different stage. The root vigor was ZGC>GC>NH and the differences of three cultivation patterns was increase with the increase of soil depth; the root vigor decreased in growing and the decreased rate was NH>GC>ZGC. The ZGC pattern has higher planting density (90000 plants/ hm2), it is effective delay the senescence after anthesis under the reasonable nutrient condition and subsoiling, the activity of SOD and POD of leaves stronger and it has lower MDA content. The same time subsoiling and postponing nitrogen application can improve the root vigor, ensure the nutrients supplying after decreased the density, which was beneficial to obtain maize high-yield.
