Professor Wan’s research has centred on peanut cultivation and cropping systems, with particular emphasis on quality-oriented cultivation and stress-resilient cultivation. Through long-term field research and technology development, he has contributed to the development of theoretical and technical approaches to high-yield peanut cultivation under different production conditions. His research and field-based programmes have supported the establishment of successive peanut yield records exceeding 500 kg, 600 kg, 750 kg, and 800 kg per mu, providing technical support for improvements in peanut yield, quality, and production efficiency. His work has also contributed to the development and application of cultivation technologies associated with the expansion and productivity of peanut production in China. Professor Wan has received four National Science and Technology Awards for work in peanut cultivation, including the National Science and Technology Progress Award (Second Prize) on four occasions, three times as the first completer and once as the fifth completer. Through sustained agricultural research, field experimentation, and engagement with major national agricultural research programmes, Professor Wan has contributed to connecting advances in crop cultivation science with practical applications in food and oil crop production, agricultural productivity, food security, and sustainable agricultural development.
