| 摘 要： | 选取2块不同种植密度的玉米样方，并分别选取4株玉米，原位测定每株玉米每个叶片主脉上5个特征点的空间坐标，并应用一般一元二次方程对玉米叶曲线进行描述，方程的系数根据实测数据由最小二乘回归方法得到，然后，通过计算机和C语言程序对玉米株叶形态结构进行了可视化模拟。可视化模拟结果与实测结果基本一致。

| Abstract: | The visualization modeling of maize canopy structure was studied in this paper. Two maize sample plots with different planting density were selected in the field, and four maize plants in each plot were studied. The spatial coordinates of five characteristic points along the coastal line of each maize leaf were determined in situ . A general quadratic equation was proposed to characterize the curvature of maize leaf, and the coefficients of the equation were determined by the method of least square regression based on the observed data, then the structure of maize leaf was modeled by using the computer. The results of visualization modeling of maize leaf structure were consistent with the actual situation of maize grown in the field. |
