Corn is dioecious with the same strain, tassel with the top of the stems of students, with the ears of students in the upper part. The ear differentiation process is different from wheat, sorghum, rice grain, rice and other crops. There have been some reports about the process of ear differentiation in maize. The materials used were local maize varieties popularized at that time. In order to grasp the relationship between the growth of male and female spikes and the growth of stems and leaves of Shanban No.7, a new hybrid variety in Shaanxi Province, and to provide the basis for proper agricultural techniques for high yielding cultivation, we observed the effects of summer sowing Shandan No.7
