Pennisetum giganteum is a natural, green, and high yield forage with rich nutritional value, good palatability, and high biomass. This article reviews the composition of Pennisetum giganteum and its advantages, challenges, and countermeasures as an earthworm bait. Pennisetum giganteum contains abundant protein, minerals (such as calcium and iron), and functional components like β-glucans and pectin. Its advantages as an earthworm bait include high productivity and nutritional value, providing a continuous organic matter supply; strong tillering ability and well-developed root systems that enhance soil nutrient cycling and create a favorable habitat for earthworms; and its perennial growth cycle (5–15 years) and low-cost organic matter production (approximately 0.17 yuan/kg), which improve economic efficiency. However, challenges such as slow biodegradation, variability in crude protein and other nutrients, and potential soil structure alterations (compaction or reduced porosity) must be addressed. To overcome these limitations, strategies such as microbial degradation, optimal harvesting timing; intercropping with high-protein forage, developing composite baitand; strengthening scientific research to accelerate decomposition and enhance utilization efficiency. This study provides a reference for the development of Pennisetum giganteum as an earthworm bait.
