Abstract: The symbiosis between solar greenhouse cucumber and vesicular-arbuscular my corrhizal fungi, the influences of the symbiosis on the growth and developments of solar greenhouse cucumber seedlings, vegetative growing, reproduction, and yield were studied in different seasons. The results showed that the vesicular-arbuscular mycorrhizal fungi can symbioses with solar greenhouse cucumber, and the infection percentage of Glomus mosseae (GM) with the solar greenhouse cucumber was the highest one; the growing and developing of solar greenhouse cucumber at different deve-
loping stage were significantly improved by the inoculat ion of vesicular-arbuscular mycorrhizal fungi in different seasons. The reasons of vesicular-arbuscular mycorrhizal fungi improving the growing and developing of solar greenhouse cucumber and the future applicat ion of vesicular-arbuscular mycorrhizal fungi also were discussed in this paper.

Key words: Vesicular-arbuscular mycorrhizal fungi, Solar greenhouse, Cucumis sativus L.
