Abstract: The experiment on two kinds of cultivation methods was carried out to study the effect of cultivation methods on photosynthetic rate，fruit yield and quality of Cucumis melo var. saccharinus. The results showed that: during the vineextend stage，the photosynthetic rate of leaves located at the lower vine under frame culture was higher than that under groundclimb culture，while，photosynthetic rate of leaves located at the upper vine under frame culture was lower than that under groundclimb culture. Photosynthetic rate changed greatly among the various growth stages. With the growth of plant，photosynthetic rate increased firstly，and then decreased. The peak of photosynthetic rate of groundclimb cultured plant emerged on 7 days after pollination，while photosynthetic rate of frame cultured plant reached maximum on 20 days after pollination. The photosynthetic rate of groundclimb cultured plant was higher than that of frame cultured plant before 7 days after pollination. Afterwards，photosynthetic rate of frame cultured plant was higher than that of groundclimb cultured plant significantly. Compared with groundclimb cultured plant，average fruit weight and soluble solid content of framed cultured plant were increased by 163%-277% and 178%-309% respectively. The framed culture method can improve the yield and quality of Hami melon.
