Rapeseed oil is a potential renewable energy source and plays an important role in the development of sustainable fuels. Improving the efficiency of biodiesel production is most important to increase rapeseed oil yield. This study hopes to find ways to increase rapeseed oil yield and biodiesel production efficiency. In our study, we compared the effects of rainwater planting and irrigation planting of rapeseed, and found that when the use of irrigation water, electricity and fungicides is reduced, and the use of certain fertilizers and diesel is increased, the rapeseed yield can be increased by 24.55%. This study analyzed and compared different fertilization methods. The use of high doses of compound fertilizers can not only increase the yield of rapeseed oil, but also increase the final biodiesel yield. Moreover, the quality of biodiesel produced by refined rapeseed oil can meet European standards. The article analyzed various factors that may affect the final yield of biodiesel, including genetic and environmental factors. The result is that the higher the efficiency of photosynthesis, the higher the yield of rapeseed oil. In order to improve the yield and quality of biodiesel, the researchers used a variety of technologies, including ultrasound-assisted and base-catalyzed transesterification. When these technologies are used under ideal conditions, the yield of biodiesel can reach 97.5%.
