This study summarized many methods to improve the energy utilization efficiency of Sorghum bicolor, including water management, farming methods, nutrient supply, biotechnology and biomass processing, etc. The results show that appropriately reducing irrigation and combining it with mulch can save water, increase yield and energy output, which is particularly effective in semi-arid and saline-alkali land. Adopting less tillage or no tillage at all, along with organic fertilizers, not only ensures stable production but also enhances energy utilization. In terms of biomass utilization, first ensiling sorghum residue with biofortification and then treating it with alkali can make it easier to decompose and utilize. Molecular breeding and bioengineering can also make sorghum more tolerant of adverse conditions such as iron deficiency and drought. Overall, integrating water, soil, nutrient management and biotechnology, and adjusting according to the conditions of different regions, is the core goal of improving the energy utilization efficiency of sorghum.
