The Institute of Materials of the Chinese Academy of Tropical Agricultural Sciences has collected and introduced more than 100 new sweet potato germplasm at home and abroad. It is a pilot project in the southern part of the new sweet potato variety in the country. Now it is screening and promoting some high-yield and high-quality new edible and high-yield forage varieties. In the case of pests and diseases, the average yield of fresh potatoes per mu planted for 4 months can reach 2-3 tons. In the future, we will continue to introduce new domestic and foreign high-yield, high-quality and specific sweet potato varieties. Through trial and extension methods such as "farmer participation", "technology-based household registration", "scientific research + government", and "scientific research + enterprise", we will establish various forms of A cooperative promotion network composed of agents and agents to accelerate the promotion and industrialization of new sweet potato varieties and technologies.
