Abstract:: Taking four ornamental sweetpotatos as material，the effect of full sunshine(100% natural light,CK)，light shading (75% natural light)，medium shading (50% natural light) and severe shading (25% natural light) on ornamental sweetpotato photosynthetic characteristics were studied.The results showed that the shade tolerance of Ipomoea batatas ‘Black Beauty’ was the best，the shade tolerance of Ipomoea batatas ‘Magarite’ and Ipomoea batatas ‘Tricolor’ was strong，and the shade tolerance of Ipomoea batatas ‘Sweet Caroline Bronze’ was the worst.
