Abstract：The effects of tillage mode and straw returning on leaf area index (LAI), grain filling rate, lower stem node, ear characters and yield of summer maize were analyzed under 5 different treatments.The re-sults showed that the grain dry weight increased rapidly in the early filling stage, and then kept slow and con-tinuous growth.Straw returning had bigger effects on maize leaf area index, and then the node length and stem diameter of lower stem node.The treatment of deep plowing alternate year and straw returning had better effects on each index of summer maize than the others.The results suggested that deep plowing and straw re-turning could increase grain dry matter accumulation and LAI, then achieve the aim of yield improvement.
