The invention provides a crystal rod test method and a crystal rod growth apparatus. The crystal rod test method comprises: providing a growing crystal rod, wherein the crystal rod has growth ridge; collecting the image data of the growth ridge; and comparing the collected image data of the growth ridge to a preset value. With the crystal rod test method and the crystal rod growth apparatus, the image data of the growth ridge of the crystal rod is collected, and the collected image data of the growth ridge is compared to the preset value, such that the crystal growth condition of the crystal rod can be timely and efficiently fed-back so as to determine whether the crystal rod normally grows; and compared to manual judgment, the method of the present invention can improve the accuracy of judgment and improve the production efficiency. 本发明提供种晶棒的测试方法以及晶棒生长装置，所述晶棒的测试方法包括：提供生长中的晶棒，所述晶棒具有生长棱线；采集所述生长棱线的图像数据；将采集的所述生长棱线的图像数据与预设值进行比较。本发明提供的晶棒的测试方法以及晶棒生长装置，通过采集晶棒的生长棱线的图像数据，并将采集的所述生长棱线的图像数据与预设值进行比较，可及时高效的反馈晶棒的长晶情况，从而确定晶棒
