| 摘 要： | 以玉米品种强盛49为试材，采用数字图像处理技术和计盒维数方法，研究了种植密度对株型的影响。结果表明，随着种植密度增加(2.4~7.8株 m-2)，植株的分形维数(FD值)从1.192逐渐下降至1.163。随着生育进程的推进，所有种植密度下FD值都呈现出先上升后下降的趋势。分形维数与株高、光合叶源和生物产量有一定的相关性。FD值是定量描述玉米株型的一种重要新性状，在作物长势与长相等生长诊断研究中有广泛的应用前景。

| Abstract: | Using fractal analysis method and image process, for corn cultivar Qiangsheng 49 was analyzed the effects of plant population density on fractal dimension (FD) of plant skeletal images. When the population density increased from 2.4 to 7.8 plants per square meters by 1.2 increment, the FD value decreased gradually from 1.192 to 1.163. Under all population density conditions, the FD values increased till early kernel filling and then decreased. The FD value was correlated with plant height, photosynthetic leaf sources and biomass to some extents. FD can be used widely in describing corn plant architecture as a new meaningful indicator. |
