摘要/Abstract

摘要： 为探讨保水剂和未来降雨变化对五叶爬山虎实生苗生长特征的影响及寻求改善生态环境的途径,在内蒙古正蓝旗育草站开展了爬山虎实生苗生长特征对水分梯度下保水剂的反应的实验。结果表明:保水剂处理更能显著提高土壤的有效含水量,并能保持较长时间;爬山虎幼苗的株长、侧枝数、叶数及茎、叶、根和植株生物量增重等指标均随施水的增多而增大,但保水剂处理增幅较大,尤其是W3和W4两种供水与对照相比均达显著水平;保水剂处理还影响植株的生物量分配,尤其对叶重比和根重比影响显著,而茎重比和根冠比两种处理差异较小。

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.

Key words: Parthenocissus quinquefolia, super absorbent polymers, water gradient, growth characteristics
