Sweet potato is a good intercropping crop because it is not as stringent as other crops. Intercropping can increase the land utilization rate, increase the interception and absorption of sunlight by the crop compound population, and the interplay between the two crops can also produce complementary effects and have certain edge-advantages. However, intense competition for sunlight, moisture, nutrients, etc. often exists between different crops during intercropping. Different crops with different heights and crop lengths, and reasonable spacing of crops with different widths in the field will help improve the intercropping effect.
