Corn's grain yield is mainly formed by the light table products of this stage. Strengthen field management, to ensure the supply of fertilizer and water, to ensure normal flowering, pollination, fruiting, maximize the green leaf area, prolong the grouting time, disaster prevention and prevention of collapse, for more grains, large grains, grain saturation, high-yield is the central task of this stage.
