Research and Application of Soilless Culture System of Ipomoea batatas

Ipomoea batatas is a kind of sprawl herb with root tuber underground, and also an important kind of upland crop in China which is originated from tropical Central America. There are many varieties for fresh eating, vegetable use and ornamental. The application of soilless culture technique on sweet potato cultivation is more and more extensive with its progressive development. This paper summarizes the research progress and achievements on the construction of sweetpotato soilless culture system, includes research contents related to sweet potato hydroponics and its pattern at home and abroad. It also expounds the application of soilless culture system on sweetpotato breeding, multiplication, production and afforestation. Some existing problems in sweetpotato soilless culture system are put forward and its prospect are outlooked.
