Firstly, the growth information of seedlings was obtained, the median filter method was used to preprocess the image, and the target area was extracted based on the Otsu automatic threshold segmentation method, through the“stacked wood”way to achieve seedling stem segmentation extraction. Stem diameter D and stem diameter variation ΔD were the input of fuzzy inference system, the output of the fuzzy inference system was the temperature setting value. Temperature was controlled by PID method to achieve the control of the temperature inside the nursery box. The experimental results showed that the system can adjust the temperature of the seedlings in real time according to the growth of the seedlings, reflect the scientific planting pattern and enhance the economic benefit, an
