Abstract
In order to study effects of super absorbent polymers and future rainfall change on growth characteristics of Parthenocissus quinquefolia seedlings, and search for a way to improve ecological environment conditions. The experiment about response of super absorbent polymers under different water gradient on growth characteristics of Parthenocissus quinquefolia seedlings was examined at Zheng Lanqi cultivating grass station in Inner Mongolia, China. The results showed that super absorbent polymers treatment can increase soil water content obviously, and keep it for quite a long time; Stem length, branch number, leaf number and biomass increment of stem, leaf, root and plants are all increased with increasing water supply, and the effect of super absorbent polymers treatment is larger than that of water gradient, especially W3 and W4 had obvious differences while comparing to contrast; Biomass allocation was significantly influenced by super absorbent polymers treatment, especially leaf weight ratio and root weight ratio, while branch weight ratio and root / shoot have little differences.
