The president has stressed the importance of food security on many occasions since the 18th National Congress of the Communist Party of China in 2012.
Last month, while meeting national political advisers from the agriculture and welfare and social security sectors in Beijing, he said that food security is among a country's most fundamental interests, and China cannot rely solely on the international market for food.
On Sunday afternoon, Xi also visited a research institute of Ocean University of China to learn about the development of marine science and technology.
It was the third inspection tour that Xi has made in the southern island province since he was elected general secretary of the CPC Central Committee in 2012.
